RSAMultiPrimePrivateCrtKeySpec JDK 1.6)

Description

public class RSAMultiPrimePrivateCrtKeySpec

This class specifies an RSA multi-prime private key, as defined in the PKCS#1 v2.1, using the Chinese Remainder Theorem (CRT) information values for efficiency.

Constructors

public 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 - 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).
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.
