Abstract: Exemplary systems and methods are directed to decrypting electronic messages in a network. The system includes a processor configured to receive or monitor message sources for encrypted messages, where private keys associated with the encrypted messages are not previously provided to the system. For each message, extract a set of user certificate identifiers and corresponding encrypted session keys, securely communicate with private key provider to decrypt the encrypted session key with an acquired private key, and decrypt the message with the unencrypted session key.
