lea-rust

lea-rust is an implementation of a 128-bit ARX block cipher LEA written in pure Rust.

Lightweight Encryption Algorithm (LEA)

Lightweight Encryption Algorithm (LEA) is a 128-bit ARX block cipher algorithm developed by the South Korean National Security Research Institute in 2013. Designed to be faster and more lightweight, it maintains enough security to be the replacement of the AES.

See https://en.wikipedia.org/wiki/LEA_(cipher) and https://seed.kisa.or.kr/kisa/algorithm/EgovLeaInfo.do for more information.

Features

Feature	Description	Default
`ccm`	LEA-CCM	false
`ctr`	LEA-CTR	false
`zeroize`	Zeroize memory containing sensitive data	false
