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
