Class RSAOtherPrimeInfo

java.lang.Object
 extended by java.security.spec.RSAOtherPrimeInfo

public class RSAOtherPrimeInfo
extends Object
extends Object

This class represents the triplet (prime, exponent, and coefficient) inside RSA's OtherPrimeInfo structure, as defined in the PKCS#1 v2.1. The ASN.1 syntax of RSA's OtherPrimeInfo is as follows:

 OtherPrimeInfo ::= SEQUENCE {
 prime INTEGER,
 exponent INTEGER,
 coefficient INTEGER
 }

Since:: 1.4
See Also:: RSAPrivateCrtKeySpec, RSAMultiPrimePrivateCrtKey

Constructor Summary
`RSAOtherPrimeInfo(BigInteger prime, BigInteger primeExponent, BigInteger crtCoefficient)` Creates a new `RSAOtherPrimeInfo` given the prime, primeExponent, and crtCoefficient as defined in PKCS#1.

Method Summary
`BigInteger`	`getCrtCoefficient()` Returns the prime's crtCoefficient.
`BigInteger`	`getExponent()` Returns the prime's exponent.
`BigInteger`	`getPrime()` Returns the prime.
