public Class RSAOtherPrimeInfo

extends Object
Class Inheritance
Imports
java.math.BigInteger
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
}
