github.com/rfjakob/eme (go): EME (ECB-Mix-ECB or, clearer, Encrypt-Mix-Encrypt) is a wide-block encryption mode developed by Halevi and Rogaway.  It was presented in the 2003 paper "A Parallelizable Enciphering Mode" by Halevi and Rogaway.  EME uses multiple invocations of a block cipher to construct a new cipher of bigger block size (in multiples of 16 bytes, up to 2048 bytes).
