You also need to be able to compute SHA1 hashes. I've been using something called "sha1file" which, I believe, originated at Adam Back's web site.
That program has a bug. The routine SHA1_update in the file sha1.c is missing a line:
while ( ctx->mlen == 64 ) { convert_to_bigendian( (word32*)ctx->M, 64 ); SHA1_transform( ctx ); use = min( 64, data_len ); memcpy( ctx->M, data, use ); ctx->mlen = use; data_len -= use; *** data += use; *** MISSING *** }
Correcting this will make your hashes be correct.
The version on my web pages for the last couple of versions has this bug fixed. http://www.dcs.ex.ac.uk/~aba/eternity/sha1.tgz Adam -- Now officially an EAR violation...
