public RSAMultiPrimePrivateCrtKeySpec(BigInteger modulus, BigInteger publicExponent, BigInteger privateExponent, BigInteger primeP, BigInteger primeQ, BigInteger primeExponentP, BigInteger primeExponentQ, BigInteger crtCoefficient, RSAOtherPrimeInfo[] otherPrimeInfo)
RSAMultiPrimePrivateCrtKeySpec
given the various PKCS#1 v2.1 parameters.
Note that otherPrimeInfo
is cloned when constructing this
object.
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).
NullPointerException
- if any of the parameters is null
.
IllegalArgumentException
- if an empty otherPrimeInfo
is specified.Method Detail |
