RSAMultiPrimePrivateCrtKeySpec

public RSAMultiPrimePrivateCrtKeySpec(BigInteger modulus,
                                      BigInteger publicExponent,
                                      BigInteger privateExponent,

                                      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 otherPrimeInfo is cloned 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.
