From ea3d5875cd8881273e02c3a0e70c7fe4317123f7 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Sun, 12 Apr 2015 16:57:25 +0100 Subject: [crypto] Add SHA-512/224 algorithm SHA-512/224 is almost identical to SHA-512, with differing initial hash values and a truncated output length. This implementation has been verified using the NIST SHA-512/224 test vectors.
