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 v2.2 standard. The ASN.1 syntax of RSA's OtherPrimeInfo is as follows:

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