Class X509CertSelector

Constructor Detail

• X509CertSelector

  public X509CertSelector()

  Creates an X509CertSelector. Initially, no criteria are set so any X509Certificate will match.

Method Detail

• setCertificate

  public void setCertificate(X509Certificate cert)

  Sets the certificateEquals criterion. The specified X509Certificate must be equal to the X509Certificate passed to the match method. If null, then this check is not applied.

  This method is particularly useful when it is necessary to match a single certificate. Although other criteria can be specified in conjunction with the certificateEquals criterion, it is usually not practical or necessary.

  Parameters:

  cert - the X509Certificate to match (or null)

  See Also:

  getCertificate()

• setSerialNumber

  public void setSerialNumber(BigInteger serial)

  Sets the serialNumber criterion. The specified serial number must match the certificate serial number in the X509Certificate. If null, any certificate serial number will do.

  Parameters:

  serial - the certificate serial number to match (or null)

  See Also:

  getSerialNumber()

• setIssuer

  public void setIssuer(X500Principal issuer)

  Sets the issuer criterion. The specified distinguished name must match the issuer distinguished name in the X509Certificate. If null, any issuer distinguished name will do.

  Parameters:

  issuer - a distinguished name as X500Principal (or null)

  Since:

  1.5

• setIssuer

  public void setIssuer(String issuerDN)
                 throws IOException

  Denigrated, use setIssuer(X500Principal) or setIssuer(byte[]) instead. This method should not be relied on as it can fail to match some certificates because of a loss of encoding information in the RFC 2253 String form of some distinguished names.

  Sets the issuer criterion. The specified distinguished name must match the issuer distinguished name in the X509Certificate. If null, any issuer distinguished name will do.

  If issuerDN is not null, it should contain a distinguished name, in RFC 2253 format.

  Parameters:

  issuerDN - a distinguished name in RFC 2253 format (or null)

  Throws:

  IOException - if a parsing error occurs (incorrect form for DN)

• setIssuer

  public void setIssuer(byte[] issuerDN)
                 throws IOException

  Sets the issuer criterion. The specified distinguished name must match the issuer distinguished name in the X509Certificate. If null is specified, the issuer criterion is disabled and any issuer distinguished name will do.

  If issuerDN is not null, it should contain a single DER encoded distinguished name, as defined in X.501. The ASN.1 notation for this structure is as follows.

  
   Name ::= CHOICE {
     RDNSequence }
  
   RDNSequence ::= SEQUENCE OF RelativeDistinguishedName
  
   RelativeDistinguishedName ::=
     SET SIZE (1 .. MAX) OF AttributeTypeAndValue
  
   AttributeTypeAndValue ::= SEQUENCE {
     type     AttributeType,
     value    AttributeValue }
  
   AttributeType ::= OBJECT IDENTIFIER
  
   AttributeValue ::= ANY DEFINED BY AttributeType
   ....
   DirectoryString ::= CHOICE {
         teletexString           TeletexString (SIZE (1..MAX)),
         printableString         PrintableString (SIZE (1..MAX)),
         universalString         UniversalString (SIZE (1..MAX)),
         utf8String              UTF8String (SIZE (1.. MAX)),
         bmpString               BMPString (SIZE (1..MAX)) }
   

  Note that the byte array specified here is cloned to protect against subsequent modifications.

  Parameters:

  issuerDN - a byte array containing the distinguished name in ASN.1 DER encoded form (or null)

  Throws:

  IOException - if an encoding error occurs (incorrect form for DN)

• setSubject

  public void setSubject(X500Principal subject)

  Sets the subject criterion. The specified distinguished name must match the subject distinguished name in the X509Certificate. If null, any subject distinguished name will do.

  Parameters:

  subject - a distinguished name as X500Principal (or null)

  Since:

  1.5

• setSubject

  public void setSubject(String subjectDN)
                  throws IOException

  Denigrated, use setSubject(X500Principal) or setSubject(byte[]) instead. This method should not be relied on as it can fail to match some certificates because of a loss of encoding information in the RFC 2253 String form of some distinguished names.

  Sets the subject criterion. The specified distinguished name must match the subject distinguished name in the X509Certificate. If null, any subject distinguished name will do.

  If subjectDN is not null, it should contain a distinguished name, in RFC 2253 format.

  Parameters:

  subjectDN - a distinguished name in RFC 2253 format (or null)

  Throws:

  IOException - if a parsing error occurs (incorrect form for DN)

• setSubject

  public void setSubject(byte[] subjectDN)
                  throws IOException

  Sets the subject criterion. The specified distinguished name must match the subject distinguished name in the X509Certificate. If null, any subject distinguished name will do.

  If subjectDN is not null, it should contain a single DER encoded distinguished name, as defined in X.501. For the ASN.1 notation for this structure, see setIssuer(byte [] issuerDN).

  Parameters:

  subjectDN - a byte array containing the distinguished name in ASN.1 DER format (or null)

  Throws:

  IOException - if an encoding error occurs (incorrect form for DN)

• setSubjectKeyIdentifier

  public void setSubjectKeyIdentifier(byte[] subjectKeyID)

  Sets the subjectKeyIdentifier criterion. The X509Certificate must contain a SubjectKeyIdentifier extension for which the contents of the extension matches the specified criterion value. If the criterion value is null, no subjectKeyIdentifier check will be done.

  If subjectKeyID is not null, it should contain a single DER encoded value corresponding to the contents of the extension value (not including the object identifier, criticality setting, and encapsulating OCTET STRING) for a SubjectKeyIdentifier extension. The ASN.1 notation for this structure follows.

  
   SubjectKeyIdentifier ::= KeyIdentifier
  
   KeyIdentifier ::= OCTET STRING
   

  Since the format of subject key identifiers is not mandated by any standard, subject key identifiers are not parsed by the X509CertSelector. Instead, the values are compared using a byte-by-byte comparison.

  Note that the byte array supplied here is cloned to protect against subsequent modifications.

  Parameters:

  subjectKeyID - the subject key identifier (or null)

  See Also:

  getSubjectKeyIdentifier()

• setAuthorityKeyIdentifier

  public void setAuthorityKeyIdentifier(byte[] authorityKeyID)

  Sets the authorityKeyIdentifier criterion. The X509Certificate must contain an AuthorityKeyIdentifier extension for which the contents of the extension value matches the specified criterion value. If the criterion value is null, no authorityKeyIdentifier check will be done.

  If authorityKeyID is not null, it should contain a single DER encoded value corresponding to the contents of the extension value (not including the object identifier, criticality setting, and encapsulating OCTET STRING) for an AuthorityKeyIdentifier extension. The ASN.1 notation for this structure follows.

  
   AuthorityKeyIdentifier ::= SEQUENCE {
      keyIdentifier             [0] KeyIdentifier           OPTIONAL,
      authorityCertIssuer       [1] GeneralNames            OPTIONAL,
      authorityCertSerialNumber [2] CertificateSerialNumber OPTIONAL  }
  
   KeyIdentifier ::= OCTET STRING
   

  Authority key identifiers are not parsed by the X509CertSelector. Instead, the values are compared using a byte-by-byte comparison.

  When the keyIdentifier field of AuthorityKeyIdentifier is populated, the value is usually taken from the SubjectKeyIdentifier extension in the issuer's certificate. Note, however, that the result of X509Certificate.getExtensionValue(<SubjectKeyIdentifier Object Identifier>) on the issuer's certificate may NOT be used directly as the input to setAuthorityKeyIdentifier. This is because the SubjectKeyIdentifier contains only a KeyIdentifier OCTET STRING, and not a SEQUENCE of KeyIdentifier, GeneralNames, and CertificateSerialNumber. In order to use the extension value of the issuer certificate's SubjectKeyIdentifier extension, it will be necessary to extract the value of the embedded KeyIdentifier OCTET STRING, then DER encode this OCTET STRING inside a SEQUENCE. For more details on SubjectKeyIdentifier, see setSubjectKeyIdentifier(byte[] subjectKeyID).

  Note also that the byte array supplied here is cloned to protect against subsequent modifications.

  Parameters:

  authorityKeyID - the authority key identifier (or null)

  See Also:

  getAuthorityKeyIdentifier()

• setCertificateValid

  public void setCertificateValid(Date certValid)

  Sets the certificateValid criterion. The specified date must fall within the certificate validity period for the X509Certificate. If null, no certificateValid check will be done.

  Note that the Date supplied here is cloned to protect against subsequent modifications.

  Parameters:

  certValid - the Date to check (or null)

  See Also:

  getCertificateValid()

• setPrivateKeyValid

  public void setPrivateKeyValid(Date privateKeyValid)

  Sets the privateKeyValid criterion. The specified date must fall within the private key validity period for the X509Certificate. If null, no privateKeyValid check will be done.

  Note that the Date supplied here is cloned to protect against subsequent modifications.

  Parameters:

  privateKeyValid - the Date to check (or null)

  See Also:

  getPrivateKeyValid()

• setSubjectPublicKeyAlgID

  public void setSubjectPublicKeyAlgID(String oid)
                                throws IOException

  Sets the subjectPublicKeyAlgID criterion. The X509Certificate must contain a subject public key with the specified algorithm. If null, no subjectPublicKeyAlgID check will be done.

  Parameters:

  oid - The object identifier (OID) of the algorithm to check for (or null). An OID is represented by a set of nonnegative integers separated by periods.

  Throws:

  IOException - if the OID is invalid, such as the first component being not 0, 1 or 2 or the second component being greater than 39.

  See Also:

  getSubjectPublicKeyAlgID()

• setSubjectPublicKey

  public void setSubjectPublicKey(PublicKey key)

  Sets the subjectPublicKey criterion. The X509Certificate must contain the specified subject public key. If null, no subjectPublicKey check will be done.

  Parameters:

  key - the subject public key to check for (or null)

  See Also:

  getSubjectPublicKey()

• setSubjectPublicKey

  public void setSubjectPublicKey(byte[] key)
                           throws IOException

  Sets the subjectPublicKey criterion. The X509Certificate must contain the specified subject public key. If null, no subjectPublicKey check will be done.

  Because this method allows the public key to be specified as a byte array, it may be used for unknown key types.

  If key is not null, it should contain a single DER encoded SubjectPublicKeyInfo structure, as defined in X.509. The ASN.1 notation for this structure is as follows.

  
   SubjectPublicKeyInfo  ::=  SEQUENCE  {
     algorithm            AlgorithmIdentifier,
     subjectPublicKey     BIT STRING  }
  
   AlgorithmIdentifier  ::=  SEQUENCE  {
     algorithm               OBJECT IDENTIFIER,
     parameters              ANY DEFINED BY algorithm OPTIONAL  }
                                -- contains a value of the type
                                -- registered for use with the
                                -- algorithm object identifier value
   

  Note that the byte array supplied here is cloned to protect against subsequent modifications.

  Parameters:

  key - a byte array containing the subject public key in ASN.1 DER form (or null)

  IOException - if an encoding error occurs (incorrect form for subject public key)

  See Also:

  getSubjectPublicKey()

• setKeyUsage

  public void setKeyUsage(boolean[] keyUsage)

  Sets the keyUsage criterion. The X509Certificate must allow the specified keyUsage values. If null, no keyUsage check will be done. Note that an X509Certificate that has no keyUsage extension implicitly allows all keyUsage values.

  Note that the boolean array supplied here is cloned to protect against subsequent modifications.

  Parameters:

  keyUsage - a boolean array in the same format as the boolean array returned by X509Certificate.getKeyUsage(). Or null.

  See Also:

  getKeyUsage()

• setExtendedKeyUsage

  public void setExtendedKeyUsage(Set<String> keyPurposeSet)
                           throws IOException

  Sets the extendedKeyUsage criterion. The X509Certificate must allow the specified key purposes in its extended key usage extension. If keyPurposeSet is empty or null, no extendedKeyUsage check will be done. Note that an X509Certificate that has no extendedKeyUsage extension implicitly allows all key purposes.

  Note that the Set is cloned to protect against subsequent modifications.

  Parameters:

  keyPurposeSet - a Set of key purpose OIDs in string format (or null). Each OID is represented by a set of nonnegative integers separated by periods.

  Throws:

  IOException - if the OID is invalid, such as the first component being not 0, 1 or 2 or the second component being greater than 39.

  See Also:

  getExtendedKeyUsage()

• setMatchAllSubjectAltNames

  public void setMatchAllSubjectAltNames(boolean matchAllNames)

  Enables/disables matching all of the subjectAlternativeNames specified in the setSubjectAlternativeNames or addSubjectAlternativeName methods. If enabled, the X509Certificate must contain all of the specified subject alternative names. If disabled, the X509Certificate must contain at least one of the specified subject alternative names.

  The matchAllNames flag is true by default.

  Parameters:

  matchAllNames - if true, the flag is enabled; if false, the flag is disabled.

  See Also:

  getMatchAllSubjectAltNames()

• setSubjectAlternativeNames

  public void setSubjectAlternativeNames(Collection<List<?>> names)
                                  throws IOException

  Sets the subjectAlternativeNames criterion. The X509Certificate must contain all or at least one of the specified subjectAlternativeNames, depending on the value of the matchAllNames flag (see setMatchAllSubjectAltNames).

  This method allows the caller to specify, with a single method call, the complete set of subject alternative names for the subjectAlternativeNames criterion. The specified value replaces the previous value for the subjectAlternativeNames criterion.

  The names parameter (if not null) is a Collection with one entry for each name to be included in the subject alternative name criterion. Each entry is a List whose first entry is an Integer (the name type, 0-8) and whose second entry is a String or a byte array (the name, in string or ASN.1 DER encoded form, respectively). There can be multiple names of the same type. If null is supplied as the value for this argument, no subjectAlternativeNames check will be performed.

  Each subject alternative name in the Collection may be specified either as a String or as an ASN.1 encoded byte array. For more details about the formats used, see addSubjectAlternativeName(int type, String name) and addSubjectAlternativeName(int type, byte [] name).

  Note: for distinguished names, specify the byte array form instead of the String form. See the note in addSubjectAlternativeName(int, String) for more information.

  Note that the names parameter can contain duplicate names (same name and name type), but they may be removed from the Collection of names returned by the getSubjectAlternativeNames method.

  Note that a deep copy is performed on the Collection to protect against subsequent modifications.

  Parameters:

  names - a Collection of names (or null)

  Throws:

  IOException - if a parsing error occurs

  See Also:

  getSubjectAlternativeNames()

• addSubjectAlternativeName

  public void addSubjectAlternativeName(int type,
                               String name)
                                 throws IOException

  Adds a name to the subjectAlternativeNames criterion. The X509Certificate must contain all or at least one of the specified subjectAlternativeNames, depending on the value of the matchAllNames flag (see setMatchAllSubjectAltNames).

  This method allows the caller to add a name to the set of subject alternative names. The specified name is added to any previous value for the subjectAlternativeNames criterion. If the specified name is a duplicate, it may be ignored.

  The name is provided in string format. RFC 822, DNS, and URI names use the well-established string formats for those types (subject to the restrictions included in RFC 3280). IPv4 address names are supplied using dotted quad notation. OID address names are represented as a series of nonnegative integers separated by periods. And directory names (distinguished names) are supplied in RFC 2253 format. No standard string format is defined for otherNames, X.400 names, EDI party names, IPv6 address names, or any other type of names. They should be specified using the addSubjectAlternativeName(int type, byte [] name) method.

  Note: for distinguished names, use addSubjectAlternativeName(int, byte[]) instead. This method should not be relied on as it can fail to match some certificates because of a loss of encoding information in the RFC 2253 String form of some distinguished names.

  Parameters:

  type - the name type (0-8, as specified in RFC 3280, section 4.2.1.7)

  name - the name in string form (not null)

  Throws:

  IOException - if a parsing error occurs

• addSubjectAlternativeName

  public void addSubjectAlternativeName(int type,
                               byte[] name)
                                 throws IOException

  Adds a name to the subjectAlternativeNames criterion. The X509Certificate must contain all or at least one of the specified subjectAlternativeNames, depending on the value of the matchAllNames flag (see setMatchAllSubjectAltNames).

  This method allows the caller to add a name to the set of subject alternative names. The specified name is added to any previous value for the subjectAlternativeNames criterion. If the specified name is a duplicate, it may be ignored.

  The name is provided as a byte array. This byte array should contain the DER encoded name, as it would appear in the GeneralName structure defined in RFC 3280 and X.509. The encoded byte array should only contain the encoded value of the name, and should not include the tag associated with the name in the GeneralName structure. The ASN.1 definition of this structure appears below.

  
    GeneralName ::= CHOICE {
         otherName                       [0]     OtherName,
         rfc822Name                      [1]     IA5String,

         registeredID                    [8]     OBJECT IDENTIFIER}
   

  Note that the byte array supplied here is cloned to protect against subsequent modifications.

  Parameters:

  type - the name type (0-8, as listed above)

  name - a byte array containing the name in ASN.1 DER encoded form

  Throws:

  IOException - if a parsing error occurs

• setNameConstraints

  public void setNameConstraints(byte[] bytes)
                          throws IOException

  Sets the name constraints criterion. The X509Certificate must have subject and subject alternative names that meet the specified name constraints.

  The name constraints are specified as a byte array. This byte array should contain the DER encoded form of the name constraints, as they would appear in the NameConstraints structure defined in RFC 3280 and X.509. The ASN.1 definition of this structure appears below.

  
    NameConstraints ::= SEQUENCE {
         permittedSubtrees       [0]     GeneralSubtrees OPTIONAL,
         excludedSubtrees        [1]     GeneralSubtrees OPTIONAL }

    GeneralSubtree ::= SEQUENCE {
         base                    GeneralName,
         minimum         [0]     BaseDistance DEFAULT 0,
         maximum         [1]     BaseDistance OPTIONAL }
  
    BaseDistance ::= INTEGER (0..MAX)
  
    GeneralName ::= CHOICE {
         otherName                       [0]     OtherName,
         rfc822Name                      [1]     IA5String,

         uniformResourceIdentifier       [6]     IA5String,
         iPAddress                       [7]     OCTET STRING,
         registeredID                    [8]     OBJECT IDENTIFIER}
   

  Note that the byte array supplied here is cloned to protect against subsequent modifications.

  Parameters:

  bytes - a byte array containing the ASN.1 DER encoding of a NameConstraints extension to be used for checking name constraints. Only the value of the extension is included, not the OID or criticality flag. Can be null, in which case no name constraints check will be performed.

  Throws:

  IOException - if a parsing error occurs

  See Also:

  getNameConstraints()

• setBasicConstraints

  public void setBasicConstraints(int minMaxPathLen)

  Sets the basic constraints constraint. If the value is greater than or equal to zero, X509Certificates must include a basicConstraints extension with a pathLen of at least this value. If the value is -2, only end-entity certificates are accepted. If the value is -1, no check is done.

  This constraint is useful when building a certification path forward (from the target toward the trust anchor. If a partial path has been built, any candidate certificate must have a maxPathLen value greater than or equal to the number of certificates in the partial path.

  Parameters:

  minMaxPathLen - the value for the basic constraints constraint

  Throws:

  IllegalArgumentException - if the value is less than -2

  See Also:

  getBasicConstraints()

• setPolicy

  public void setPolicy(Set<String> certPolicySet)
                 throws IOException

  Sets the policy constraint. The X509Certificate must include at least one of the specified policies in its certificate policies extension. If certPolicySet is empty, then the X509Certificate must include at least some specified policy in its certificate policies extension. If certPolicySet is null, no policy check will be performed.

  Note that the Set is cloned to protect against subsequent modifications.

  Parameters:

  certPolicySet - a Set of certificate policy OIDs in string format (or null). Each OID is represented by a set of nonnegative integers separated by periods.

  Throws:

  IOException - if a parsing error occurs on the OID such as the first component is not 0, 1 or 2 or the second component is greater than 39.

  See Also:

  getPolicy()

• setPathToNames

  public void setPathToNames(Collection<List<?>> names)
                      throws IOException

  Sets the pathToNames criterion. The X509Certificate must not include name constraints that would prohibit building a path to the specified names.

  This method allows the caller to specify, with a single method call, the complete set of names which the X509Certificates's name constraints must permit. The specified value replaces the previous value for the pathToNames criterion.

  This constraint is useful when building a certification path forward (from the target toward the trust anchor. If a partial path has been built, any candidate certificate must not include name constraints that would prohibit building a path to any of the names in the partial path.

  The names parameter (if not null) is a Collection with one entry for each name to be included in the pathToNames criterion. Each entry is a List whose first entry is an Integer (the name type, 0-8) and whose second entry is a String or a byte array (the name, in string or ASN.1 DER encoded form, respectively). There can be multiple names of the same type. If null is supplied as the value for this argument, no pathToNames check will be performed.

  Each name in the Collection may be specified either as a String or as an ASN.1 encoded byte array. For more details about the formats used, see addPathToName(int type, String name) and addPathToName(int type, byte [] name).

  Note: for distinguished names, specify the byte array form instead of the String form. See the note in addPathToName(int, String) for more information.

  Note that the names parameter can contain duplicate names (same name and name type), but they may be removed from the Collection of names returned by the getPathToNames method.

  Note that a deep copy is performed on the Collection to protect against subsequent modifications.

  Parameters:

  names - a Collection with one entry per name (or null)

  Throws:

  IOException - if a parsing error occurs
