IPSECers: We just ran some independent tests with our SHA-1 implemntation. We ran 10,000,000 bytes through the hash function. On a 486/66 PC, we got around 160,000 bytes/sec. On a Sun SPARC20 (single CPU), we got around 2,070,000 bytes/sec. In both cases, the code was compiled with speed optimization on. Russ
