2020-06-12Add support for SHA384 and SHA512Reuben Dowle
The current recommendation for best security practice from the US government is to use SHA384 for TOP SECRET [1]. This patch adds support for SHA384 and SHA512 in the hash command, and also allows FIT images to be hashed with these algorithms, and signed with sha384,rsaXXXX and sha512,rsaXXXX The SHA implementation is adapted from the linux kernel implementation.
