I just wrote this, and still consider it a stub even though it's moderately detailed and long than most stubs. I'm conflicted over whether to break it into two pages or just keep it as one for now to emphasize the differences between the to. I'd love to confirm that some versions of UNIX shipped with a crippled Ceasar cipher implementation of the crypt(1) command with some clearly documented references. JimD 05:15, 24 February 2006 (UTC)
"The source code to the legacy version of the crypt command do not seem to be readily available"
what? it's right here: http://google.com/codesearch/p?hl=en#118goTAkg2o/usr/src/cmd/crypt.c
the archive that contains that file is here: http://www.tuhs.org/Archive/PDP-11/Distributions/research/Henry_Spencer_v7/v7.tar.gz and there's an older version of the crypt command here: http://www.tuhs.org/Archive/PDP-11/Distributions/research/Dennis_v6/v6src.tar.gz
I would suggest that this article be restructured. The original crypt(1) utility is of only the mildest historical interest, and is not present on modern Linux systems. It should either be elided, or moved to its own page if people think that having an ancient man page in Wikipedia would be useful. All real interest now is in the cryptographic algorithms used by the crypt(3) function. Jonabbey (talk) 15:55, 21 August 2012 (UTC)
