Class RSAOtherPrimeInfo

• java.lang.Object
• • java.security.spec.RSAOtherPrimeInfo

public class RSAOtherPrimeInfo
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

Constructors

RSAOtherPrimeInfo

public RSAOtherPrimeInfo(BigInteger prime,
                         BigInteger primeExponent,
                         BigInteger crtCoefficient)

Creates a new RSAOtherPrimeInfo given the prime, primeExponent, and crtCoefficient as defined in PKCS#1.

Parameters:

prime - the prime factor of n.

primeExponent - the exponent.

crtCoefficient - the Chinese Remainder Theorem coefficient.

Throws:

NullPointerException - if any of the parameters, i.e. prime, primeExponent, crtCoefficient, is null.
