What tool can generate MD5 from the command-line? [closed]

The hashutils package has an md5sum.exe utility. It simply uses Microsoft's Crypto APIs and will leave you I/O bound, which isn't necessarily the case with other tools. For example, I've benchmarked the md5sum from UnxUtils against this one and UnxUtils is significantly slower. I bet CygWin would be even worse. The author also wrote the excellent HashCheck, a shell extension for hash generation & verification.

Check out MS Support - Availability and description of the File Checksum Integrity Verifier utility:

The File Checksum Integrity Verifier (FCIV) is a command-prompt utility that computes and verifies cryptographic hash values of files. FCIV can compute MD5 or SHA-1 cryptographic hash values. These values can be displayed on the screen or saved in an XML file database for later use and verification.

md5sum is included in the coreutils package of GnuWin32.
