This package contains code retrieved from https://github.com/codahale/etm on 2021-10-28. It implements the crypto.AEAD interface using AES-CBC encryption and sha hashing algorithms. It was stripped of all aead constructions other than AEAD_AES_256_CBC_HMAC_SHA_512
to fit our usage.
# Functions
NewAES256SHA512 returns an AEAD_AES_256_CBC_HMAC_SHA_512 instance given a 64-byte key or an error if the key is the wrong size.
