                                      RSAOtherPrimeInfo[] otherPrimeInfo)

Enabled: 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).
