RSAMultiPrimePrivateCrtKeySpec (BigInteger modulus, BigInteger publicExponent, BigInteger privateExponent, BigInteger primeP, BigInteger primeQ, BigInteger primeExponentP, BigInteger primeExponentQ, BigInteger crtCoefficient, RSAOtherPrimeInfo[] otherPrimeInfo)
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 the contents of otherPrimeInfo
are copied to protect against subsequent modification when
constructing this object.
| Parameters | |
|---|---|
modulus |
BigInteger:
the modulus n. |
publicExponent |
BigInteger:
the public exponent e. |
privateExponent |
BigInteger:
the private exponent d. |
primeP |
BigInteger:
the prime factor p of n. |
primeQ |
BigInteger:
the prime factor q of n. |
primeExponentP |
BigInteger:
this is d mod (p-1). |
primeExponentQ |
BigInteger:
this is d mod (q-1). |
crtCoefficient |
BigInteger:
the Chinese Remainder Theorem
coefficient q-1 mod p. |
otherPrimeInfo |
RSAOtherPrimeInfo:
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 parameters, i.e.
modulus,
publicExponent, privateExponent,
primeP, primeQ,
primeExponentP, primeExponentQ,
crtCoefficient, is null. |
IllegalArgumentException |
if an empty, i.e. 0-length,
otherPrimeInfo is specified.
