Verifying Downloads with MD5

Today I downloaded Valgrind and wanted to verify the download's integrity. Valgrind provides an MD5 digest with each release that you can check against.

I used OpenSSL's md5 on OSX:

$ md5 valgrind-3.11.0.tar.bz2
MD5 (valgrind-3.11.0.tar.bz2) = 4ea62074da73ae82e0162d6550d3f129

This matches the digest on the Valgrind website, verifying the download. md5sum would be a comparable Linux program.
