RSAMultiPrimePrivateCrtKeySpec
public RSAMultiPrimePrivateCrtKeySpec(BigInteger modulus, BigInteger publicExponent, BigInteger privateExponent, BigInteger primeP, BigInteger primeQ, BigInteger primeExponentP, BigInteger primeExponentQ, BigInteger crtCoefficient, RSAOtherPrimeInfo[] otherPrimeInfo)
Creates a newRSAMultiPrimePrivateCrtKeySpec.Note that the contents of
otherPrimeInfoare copied to protect against subsequent modification when constructing this object.- Parameters:
modulus- the modulus npublicExponent- the public exponent eprivateExponent- the private exponent dprimeP- the prime factor p of nprimeQ- the prime factor q of qprimeExponentP- this is d mod (p-1)primeExponentQ- this is d mod (q-1)crtCoefficient- the Chinese Remainder Theorem coefficient q-1 mod potherPrimeInfo- 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 specified parameters with the exception ofotherPrimeInfois nullIllegalArgumentException- if an empty, i.e. 0-length,otherPrimeInfois specified
