A Lua frontend to OpenSSL


LuaCrypto provides a Lua frontend to the OpenSSL cryptographic library. The OpenSSL features that are currently exposed are digests (MD5, SHA-1, HMAC, and more) and crypto-grade random number generators.

LuaCrypto is free software and uses the same license as Lua 5.0. It is currently a stand-alone component with the goal of eventually becoming part of the Kepler Project.


Current version is 0.3.0. It was developed for Lua 5.1 but it is compatible with Lua 5.0 through the use of Compat-5.1.


LuaCrypto can be downloaded from GitHub project page.

Much of the original release was based on the lmd5 project, written by Luiz Henrique de Figueiredo. More recent versions were based on existing Kepler components and also incorporate changes contributed by Mark Edgar. Encryption and decryption support was added by Michal Kottman, additional functionality and fixes were contributed by Ignacio BurgueƱo, Aleksandr Novitskiy and Brandon Philips.


The project is currently maintained by Michal Kottman on GitHub, where you can file bug reports, feature requests and contribute modifications.
