Unknown	84702995f8	A better-scheduled PPC SHA-1 implementation. ... This is about 15% faster that the current sha1ppc.S on a G4, and 5% faster on a G5 when hashing 10 million bytes, unaligned. (The G5 ratio seems to get better as the sizes fall.) It's also somewhat smaller, due to using load-multiple instructions.

Paul Mackerras	b47f509ba5	Fix PPC SHA1 routine for large input buffers ... The PPC SHA1 routine had an overflow which meant that it gave incorrect results for input buffers >= 512MB. This fixes it by ensuring that the update of the total length in bits is done using 64-bit arithmetic.

Paul Mackerras	a6ef3518f9	[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.
