From 71ebc4d1b27d345342bdcb32a29c8cc3da8c6654 Mon Sep 17 00:00:00 2001 From: Martin Willi Date: Mon, 1 Jun 2015 13:44:00 +0200 Subject: crypto: chacha20poly1305 - Add a ChaCha20-Poly1305 AEAD construction, RFC7539 This AEAD uses a chacha20 ablkcipher and a poly1305 ahash to construct the ChaCha20-Poly1305 AEAD as defined in RFC7539. It supports both synchronous and asynchronous operations, even if we currently have no async chacha20 or poly1305 drivers.
