Jim Reeds broke UNIX crypt long ago. The decrypt program takes about an hour to recover the plaintext. It is certainly not trivial tho, and I would not expect very many people would know the method. I should also mention that the decrypt is NOT available to anyone.

Crypt(1) was broken by Jim Reeds. Bob Morris Sr. then wrote an improved version and Jim Reeds and Peter Weinberger broke that. You cannot use "long keys" in crypt(1). Like the UNIX password system, it simply throws away everything after the eighth character. We wrote a new crypt program based on DES. No one was interested in it, and it was never released.
