s7e9h3n, since you don't appear to be a Linux guy, what about installing OpenSSL for Windows (light version: only 1 MB) ? Get it from [1]. Then assuming you install it in the default location (C:\OpenSSL), open a command prompt and run this (if you get an error "MSVCR71.DLL could not be found", install Microsoft .NET Framework 1.1 [2] and copy C:\winnt\microsoft.net\framework\v1.1.4322\msvcr71 .dll to C:\openssl\bin\):

Code:
C:\> cd openssl\bin
C:\> openssl speed
"openssl speed" should take about 10 min to complete (single threaded by default, the Linux version can be run in multi-threaded mode), it benchmarks:

md2, md4, md5, hmac(md5), sha1, sha256, sha512, rmd160, rc4, des, triple des, aes-128, aes-192, aes-256, idea, rc2, blowfish, cast, 512-bit rsa, 1024-bit rsa, 2048-bit rsa, 4096-bit rsa, 512-bit dsa, 1024-bit dsa, 2048-bit dsa.

All these algorithms are 100% ALU code (except on Linux, where sha512 uses SSE2), some are coded in C, others are in assembly. They all scale pretty much linearly with the clock frequency. They should all easily fit in the Barcelona L2 cache so they should not be influenced by the memory subsystem at all. The only downside of the Windows version is that it is compiled as a 32-bit executable. Some algorithms would see a significant gain by running in 64-bit mode: RSA and DSA would be about 3 times faster, RC4 30% faster, MD5 15% faster, etc. Anyway see below for a table of results I obtain on a old Pentium M 1.2 GHz: the fastest hash algorithm is MD4 (240 MB/s) and the fastest symmetric cryptographic algorithm is RC4 (173 MB/s).

Others should run this benchmark on Intel Core-based CPUs so we can compare against Barcelona...
