**EME** (ECB-Mix-ECB) is a tweakable enciphering scheme introduced by Shai Halevi and Phillip Rogaway in 2003.

This implementation is based on https://github.com/rfjakob/eme and https://github.com/jmesmon/rust-eme.

It is generic over the used cipher and padding, but only supports ciphers with a 128 bit (16 Byte) block size.

## Minimum Supported Rust Version

This crate will follow the MSRV of the [RustCrypto][1] project, which  currently requires Rust **1.56** or higher.

Minimum supported Rust version can be changed in the future, but it will be
done with a minor version bump.

## SemVer Policy

- All on-by-default features of this library are covered by SemVer
- MSRV is considered exempt from SemVer as noted above
