Constructor Detail- 
RSAMultiPrimePrivateCrtKeySpecpublic 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 n
- publicExponent- the public exponent e
- privateExponent- the private exponent d
- primeP- the prime factor p of n
- primeQ- the prime factor q of q
- 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 specified parameters with the exception of- otherPrimeInfois null
- IllegalArgumentException- if an empty, i.e. 0-length,- otherPrimeInfois specified
