From efd19aa7c15d88ceff9587c5c9d535aecda7963b Mon Sep 17 00:00:00 2001 From: Conrad Meyer Date: Mon, 9 Jul 2018 07:24:05 +0000 Subject: Implement SHA2-224 submode of SHA2-256 Like SHA2-384:SHA2-512, SHA2-224 is simply a truncated SHA2-256 with a different initial vector. Add to round out the complete basic SHA2 family. --- cpukit/include/sha224.h | 62 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 cpukit/include/sha224.h (limited to 'cpukit/include') diff --git a/cpukit/include/sha224.h b/cpukit/include/sha224.h new file mode 100644 index 0000000000..3085c7fcb2 --- /dev/null +++ b/cpukit/include/sha224.h @@ -0,0 +1,62 @@ +/*- + * Copyright 2005 Colin Percival + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
