Class RSAMultiPrimePrivateCrtKeySpec

Constructor Detail

• RSAMultiPrimePrivateCrtKeySpec

  public RSAMultiPrimePrivateCrtKeySpec(BigInteger modulus,
                                BigInteger publicExponent,
                                BigInteger privateExponent,
                                BigInteger primeP,
                                BigInteger primeQ,
                                BigInteger primeExponentP,
                                BigInteger primeExponentQ,
                                BigInteger crtCoefficient,
                                RSAOtherPrimeInfo[] otherPrimeInfo)

  Creates a new RSAMultiPrimePrivateCrtKeySpec given the modulus, publicExponent, privateExponent, primeP, primeQ, primeExponentP, primeExponentQ, crtCoefficient, and otherPrimeInfo as defined in PKCS#1 v2.1.

  Note that the contents of otherPrimeInfo are copied to protect against subsequent modification when constructing this object.

  Parameters:

  modulus - the modulus n.

  publicExponent - the public exponent e.

  privateExponent - the private exponent d.

  primeP - the prime factor p of n.

  primeQ - the prime factor q of n.

  primeExponentP - this is d mod (p-1).

  primeExponentQ - this is d mod (q-1).

  crtCoefficient - the Chinese Remainder Theorem coefficient q-1 mod p.

  otherPrimeInfo - triplets of the rest of primes, null can be specified if there are only two prime factors (p and q).

  Throws:

  NullPointerException - if any of the parameters, i.e. modulus, publicExponent, privateExponent, primeP, primeQ, primeExponentP, primeExponentQ, crtCoefficient, is null.

  IllegalArgumentException - if an empty, i.e. 0-length, otherPrimeInfo is specified.
