We show software agents that operate on input plaintext, transmit the result, and have the property that characterizes the operation as theft of plaintext amounts to solving a hard cryptographic problem. Such agents employ what we call a "questionable encryption scheme" in which it is computationally intractable to determine if the output is an asymmetric ciphertext or nonce. We therefore show a fundamental computational limitation of information forensics
