From 02879299c96e02e0ad6093d86b04468ab89d3cfe Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Sun, 12 Apr 2015 15:53:39 +0100 Subject: [crypto] Add SHA-384 algorithm SHA-384 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-384 test vectors.
