cvs commit: src/usr.bin/enigma enigma.1

[Jim Rees]

  You may want to amend it into the 21st century regarding what the 
  alternatives are for "real" encryption -- perhaps replace all of the 
  mentioned alternatives with openssl(1), or just replace bdes(1)...

You might also want to clarify that the encryption is a simple single rotor,
not the more difficult (but still unsafe) German military Enigma.

Someone should also fix the bdes(1) man page, which still says, "DES is
considered a very strong cryptosystem" and "key search attacks... are very
expensive and time-consuming."  Just taking out "very" in both places might
be enough.  And add a pointer to openssl(1) for something stronger.
