shell command : "crypt"

Hi,

Does anyone know what is the equivalent "crypt" command on Linux? I am using the command to encode or decode a file on HP-UX but couldn't find it on Linux.

Thanks.

hi,

It seem that crypt command is not implemented on Linux because USA export restrictions. But of course crypt(3) library exist (use by passwd).
See below if you want to create command. It's perhaps a solution (i have not test it).

I think it is available on some linux versions. See this article.

I don't use and did not find it on my linux.

From what I remember crypt doesn't use a reasonably strong encryption, so better think of it as a scrambling and checksumming mechanism :)

no points please...

Just had to share an old joke...

Using crypt is like locking the doors on your car with the window rolled down!!! It only keeps the honest folks out.

Don't use it! The command "crypt" is not considered secure and hasn't for many years. Instead, check out PGP--Pretty Good Privacy at http://www.pgpi.org.
