tlock is a library to encrypt and decrypt 16-byte binaries using tlock scheme. It provides encrypt and decrypt methods consuming Threshold BLS signatures provided by drand beacons.
The reference interroperable Go implementation is available at drand/tlock.
| Environment | CLI Command |
|:-------------------|:--------------------------|
| Cargo (Rust 1.67+) | cargo install tlock |
The library is tested against the following targets: x86_64-unknown-linux-gnu, armv7-unknown-linux-gnueabihf, aarch64-unknown-linux-gnu, wasm32-wasi.
Code examples are provided in tlock/examples.
The tlock system relies on unchained drand networks.
This crate does not provide a drand client. You can use drand_core.
This software has not been audited. Please use at your sole discretion. With this in mind, dee security relies on the following: * tlock: Practical Timelock Encryption from Threshold BLS by Nicolas Gailly, Kelsey Melissaris, and Yolan Romailler, and its implementation in drand/tlock, * Identity-Based Encryption by Dan Boneh, and Matthew Franklin, and its implementation in thibmeu/tlock-rs, * The choosen drand beacon to remain honest,
You should consider using tlock_age. It relies on this library to encrypt an age filekey, allowing for file of arbitrary size to use timelock-encryption.
For the simple explanation, you can use Handwaving Cryptography.
For a more detailed one, you should take time to read tlock: Practical Timelock Encryption from Threshold BLS by Nicolas Gailly, Kelsey Melissaris, and Yolan Romailler.
