cryptix.jce.provider.pk
Class RSAPublicKeyImpl  

java.lang.Object
  cryptix.jce.provider.pk.RSAPublicKeyImpl

All Implemented Interfaces:

java.security.Key, java.security.PublicKey, java.security.interfaces.RSAKey, java.security.interfaces.RSAPublicKey, java.io.Serializable

---

public final class RSAPublicKeyImpl

extends java.lang.Object

implements java.security.interfaces.RSAPublicKey

RSAPublicKey implementation that encodes itself in X.509 format.

 X.509 encoding is DER-encoded ASN.1:

 SEQUENCE
   AlgorithId  id
   BIT_STRING  key

 where key is the DER-encoding of:

 SEQUENCE
   INTEGER  modulus
   INTEGER  exponent
 

Version:

$Revision: 1.3 $
