There are two AEAD modes supported by OpenSSL (up to version 1.0.2) - GCM (Galois Counter Mode) and CCM (Counter with CBC-MAC).

The Advanced Encryption Standard (AES) is a specific subset of a block cipher called Rijndael. Rijndael’s design is based on a substitution-permutation network, which broke tradition from many block ciphers of its era (including its predecessor, DES) in not using a Feistel network.


multiplexing: portable C (Chacha-Poly only); AVX (Chacha-Poly); AVX2 (Chacha-Poly); AESNI + CLMUL (AES128-GCM, AES256-GCM) stateful. Possible values for the agility argument ( Hacl_Spec.h) : #define Spec_Agile_AEAD_AES128_GCM 0 #define Spec_Agile_AEAD_AES256_GCM 1 #define Spec_Agile_AEAD_CHACHA20 The AEAD requirements are provided in [44, Section 3.1]. Grain-128AEAD takes a variable-length plaintext, variable-length associ-ated data, a xed-length nonce (IV) of size 96 bits, and a xed-length key of size 128 bits. The output is a variable length ciphertext. The plaintext LOTUS-AEAD and LOCUS-AEAD, achieve higher NAEAD security bounds with lighter primitives. They allow close to 264 data and 2128 time limit, when instantiated by a block cipher with 64-bit block and 128-bit key. Notably, they satisfy the NIST lightweight standardization requirements, even with a 64-bit The following guide discusses installation on the Miller® AEAD series.
