Tequel
For educacional purposes only, but still usable.
A authenticated simetric encrypt engine (AEAD) built in Rust.
This project was designed to explore byte's manipulation concepts, XOR and modular-aritmetic in Rust. Not is recommended to use in high-safe systems, but yes like a tool to learn about how data can be converted and recovered through dynamic keys.

Summary
Security Notice
Tequel is an experimental cryptographic implementation and should not be used in production environments (if you want).
⚙️ What does Tequel do?
- Confidentiality: Uses XOR operations, Modular-Arithmetic, Wrapping among constants to "mask" data.
- Integrity (MAC): Validates if data was modified before decryption.
- Salting: Generates random salts to guarantee that the same input generates different results.
- Based in Encrypt-then-MAC (EtM): Smarter Security and validation of internal changes.
📥 How to Install and Use
- Install with Cargo
cargo install tequel-rs
- Add in your
cargo.toml's project
[]
= "0.2.2"
- Use in your project

⁉️ Guide
Welcome to Tequel's Guide, here you will understand how each function of Tequel works.
- Tequel RNG — Low-level random number generation.
- Tequel Hash — Deterministic and non-deterministic hashing.
- Tequel Encryption — Authenticated encryption flow.
Why the name 'Tequel'?
"Tequel" is a biblical reference from the Book of Daniel.
"Mene, Mene, Tequel, Parsim" — Daniel 5:25-28
This is a mysterious Aramaic phrase written by a divine hand on the wall during the Babylonian King Belshazzar's feast.
The prophet Daniel interpreted the message, which announced the end of Belshazzar's reign: God had numbered the kingdom, weighed the king, and divided the empire between the Medes and Persians. The kingdom fell that very night.
TEQUEL means "Weighed" or "Heavy." I chose this name because:
The Mystery: The message was "decrypted" by Daniel, a perfect metaphor for an encryption library.
The Weight: It represents the "heavy" security and robustness that Tequel provides to your data.
