RSAMultiPrimePrivateCrtKeySpec

public class RSAMultiPrimePrivateCrtKeySpec
extends RSAPrivateKeySpec

java.lang.Object
   ↳ java.security.spec.RSAPrivateKeySpec
     ↳ java.security.spec.RSAMultiPrimePrivateCrtKeySpec

该类使用中国剩余定理（CRT）信息值来指定RSA多主密钥，如PKCS＃1 v2.1中所定义的那样，以提高效率。

RSAMultiPrimePrivateCrtKeySpec

Added in API level 1 
RSAMultiPrimePrivateCrtKeySpec (BigInteger modulus, 
                BigInteger publicExponent, 
                BigInteger privateExponent, 
                BigInteger primeP, 
                BigInteger primeQ, 
                BigInteger primeExponentP, 
                BigInteger primeExponentQ, 
                BigInteger crtCoefficient, 
                RSAOtherPrimeInfo[] otherPrimeInfo)

根据PKCS＃1 v2.1中定义的模数，publicExponent，privateExponent，primeP，primeQ，primeExponentP，primeExponentQ，crtCoefficient和otherPrimeInfo创建新的 RSAMultiPrimePrivateCrtKeySpec 。

请注意，复制 otherPrimeInfo的内容是为了防止构建此对象时的后续修改。

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.
