Description

### Summary

Support for the EME (ECB-Mix-ECB) Mode for AES would be great. EME is a wide-block encryption mode presented in the 2003 paper “A Parallelizable Enciphering Mode” by Halevi and Rogaway (http://seclab.cs.ucdavis.edu/papers/eme.pdf). This is used for deterministic encryption.

### Example

An example project using this encryption is rclone (https://rclone.org/crypt/#name-encryption).
