public class: RSAMultiPrimePrivateCrtKeySpec [javadoc | source]
java.lang.Object
   java.security.spec.RSAPrivateKeySpec
      java.security.spec.RSAMultiPrimePrivateCrtKeySpec

All Implemented Interfaces:
    KeySpec

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.
Constructor:
 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.
    exception: NullPointerException - if any of the parameters, i.e. modulus, publicExponent, privateExponent, primeP, primeQ, primeExponentP, primeExponentQ, crtCoefficient, is null.
    exception: IllegalArgumentException - if an empty, i.e. 0-length, otherPrimeInfo is specified.
