It is present in OS Xs Fink, Homebrew and MacPorts projects. Md5deep exists for Windows and most Unix-based systems, including OS X. On Unix-like systems, similar functionality can be often obtained by combining find with hashing utilities such as md5sum, sha256sum, or tthsum. Its recursive behavior is approximately a depth-first search, which has the benefit of presenting files in lexicographical order. Typically users operate it recursively, where md5deep walks through one directory at a time giving digests of each file found, and recursing into any subdirectories within. Md5deep can be invoked in several different ways. Thus, the name may confuse some people into thinking it only provides the MD5 algorithm when the package supports many more. As of version 2.0, the md5deep package contains several different programs able to perform MD5, SHA-1, SHA-256, Tiger192 and Whirlpool digests, each of them named by the digest type followed by the word deep. It was originally authored by Jesse Kornblum, at the time a Special Agent of the Air Force Office of Special Investigations. Md5deep is a software package used in the computer security, system administration and computer forensics communities to run large numbers of files through any of several different cryptographic digests.
