public class PKCS8EncodedKeySpec extends EncodedKeySpec
This class represents the ASN.1 encoding of a private key, encoded according to the ASN.1 typePrivateKeyInfo
. ThePrivateKeyInfo
syntax is defined in the PKCS#8 standard as follows:PrivateKeyInfo ::= SEQUENCE { version Version, privateKeyAlgorithm PrivateKeyAlgorithmIdentifier, privateKey PrivateKey, attributes [0] IMPLICIT Attributes OPTIONAL } Version ::= INTEGER PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING Attributes ::= SET OF Attribute
