[PATCH] PPC assembly implementation of SHA1
Here is a SHA1 implementation with the core written in PPC assembly. On my 2GHz G5, it does 218MB/s, compared to 135MB/s for the openssl version or 45MB/s for the mozilla version. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
