From 48fb3e5785be7ef69a43c04f617a1c05000ee2d0 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Thu, 2 Jan 2020 20:04:35 -0800 Subject: crypto: hash - add support for new way of freeing instances Add support to shash and ahash for the new way of freeing instances (already used for skcipher, aead, and akcipher) where a ->free() method is installed to the instance struct itself. These methods are more strongly-typed than crypto_template::free(), which they replace. This will allow removing support for the old way of freeing instances.
