On: The Coder Who Encrypted Your Texts

[ikawe]

I'm ignorant. How can you prove that it's encrypted in any meaningful fashion vs, say rot13?

[lovemenot → ikawe]

We can disprove the existence of strong encryption with a wireshark, but cannot prove it.

Entropy of a rot13 message would be much lower than that of a properly encrypted channel. High entropy is not proof of "meaningful encryption", mind you, since a compressed rot13 or plaintext message would have high entropy too.
