**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
