We present Tortoise, an experimental nonce-based authenticated encryption scheme modeled on the Synthetic Counter-in-Tweak framework to convert any block cipher into Authenticated Encryption with Associated Data. Our work supports two modes: nonce-respecting and nonce-misuse-resistant. Source code available at <https://github.com/kenluck2001/cipherResearch/tree/main/src/tortoise>.
