                            BigInteger crtCoefficient)

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

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
