The enigma encryption algorithm used in crypt(1) (also available in
mcrypt(1)) has known vulnerabilities.
Hint: Crypt Breaker's Workbench

P.S. It's a relatively common mistake for users of vi or ex which are
crypt enabled, to accidentally crypt(1) a file with this built-in
capability. The best defense for this is realizing what has occurred
before exiting the vi session, and writing and confirming that one has
written a file as one desires (either in plain text, or confirming one
knows what the key is and that it works as expected). Unfortunately
the "accidental crypt" mistake typically also includes not knowing the
key.
