List of doPhase() Examples

Examples of doPhase()

javax.crypto.KeyAgreement.doPhase()
Does the next (or the last) phase of the key agreement, using the specified key. @param key the key received from the other party for this phase. @param lastPhase set to {@code true} if this is the last phase of this keyagreement. @return the intermediate key from this phase or {@code null} if there isno intermediate key for this phase. @throws InvalidKeyException if the specified key cannot be used in this key agreement or this phase, @throws IllegalStateException if this instance has not been initialized.

Examples of javax.crypto.KeyAgreement.doPhase()

      KeyFactory keyFact = KeyFactory.getInstance(ALGORITHM);
      PublicKey publicKey = keyFact.generatePublic(x509KeySpec);


      KeyAgreement ka = KeyAgreement.getInstance(ALGORITHM);
      ka.init(privateKey);
      ka.doPhase(publicKey, true);
      byte[] secret = ka.generateSecret();


      MessageDigest sha = MessageDigest.getInstance(DIGEST);
      byte[] hash = sha.digest(secret);
      byte[] symKey = new byte[keySize / 8];
