RSAMultiPrimePrivateCrtKeySpec

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

                                      BigInteger primeExponentP,
                                      BigInteger primeExponentQ,
                                      BigInteger crtCoefficient,
                                      RSAOtherPrimeInfo[] otherPrimeInfo)
Constructs a new instance of RSAMultiPrimePrivateCrtKeySpec given the various PKCS#1 v2.1 parameters.

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 is null.
IllegalArgumentException - if an empty otherPrimeInfo is specified.
