        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.
