PurrCrypt: Steganographic encryption disguised as pet sounds

Technically, disguised as pet onomatopoeia. I was so hoping for actual sounds. :)

This is great.

Tip

For the best experience, try saying "meow" or "woof" out loud while your encryption runs. It doesn't affect the algorithm at all, but it does make you feel more connected to the process!

I am surprised to see this is using AES-GCM instead of XChaCha20-Poly1305 for its authenticated encryption scheme.

The poor cats and dogs need special hardware for speedy encryption, and can't accidentally reuse nonces without catastrophic failure :(

For those interested in steganography-based encryption techniques, some well-known cryptology researchers designed a system for formally transforming encrypted messages into the (well-formed) contents of arbitrary protocols or communication mediums. The technique is called format transforming encryption [1], and it could be applicable here to help conceal the very presence of encryption being used by one who knows the stegonagraphic scheme.

Thank you vxfemboy, you're doing the lord's work

I want my phone to meow my text messages, encrypted with PurrCrypt, instead of the notification sounds.

This can be combined with adding steganographic noise in form of AI-generated human speech intersecting the encrypted words.

Damn, was thinking it used audio. Lame.

Underrated. And magnificent.

Of course its written in rust
