Class 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
