- sun has unbundled crypt(1) and des(1). anyway, forget crypt(1). it's
- weak. use archie(1) to find an anon ftp site that carries des source
- code (i use the des(1) found within the kit-2.0.14 package).
-
- as for des(1) being silly to use, the succeptibility of des to brute
- force attack is dwarfed by the key management problem on networked
- machines. if you want more security than des(1) provides, forward- and
- backward-encrypt multiple times using different keys. see the sci.crypt
- faq for more info.
