  • 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.
