  - ### Method Detail

    - #### decrypt

          public BuildRequestRecord decrypt(TunnelBuildMessage msg,
                                            Hash ourHash,
                                            PrivateKey privKey)

      Decrypt the record targeting us, encrypting all of the other records with the included reply key and IV. The original, encrypted record targeting us is removed from the request message (so that the reply can be placed in that position after going through the decrypted request record). Note that this layer-decrypts the build records in-place. Do not call this more than once for a given message.
      Returns:
        the current hop's decrypted record or null on failure
