public RSAMultiPrimePrivateCrtKeySpec(BigInteger modulus,
                              BigInteger publicExponent,
                              BigInteger privateExponent,

                              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.
