3.3.7.3 Decrypting a Message

When P2P Graphing requests that a message be decrypted, the message MUST be passed to the TLS implementation for decryption. If the decryption is successful, the decrypted message MUST be returned to P2P Graphing; otherwise, the message MUST be silently discarded and P2P Graphing MUST be notified of the failure with a nonzero return value.
