Why not just use the crypt(1) filter program? Assuming you are using unix.
My system also provides the library function run_encrypt(3X) which handles
the neccesary popen() calls to crypt(1) from inside your program. This is
(BTW) how vi can encrypt/decrypt your files while letting you work in
plaintext. If you want the sources to a public domain DES c version, they
are even on the net or avaliable via anon ftp. Reply to this post and I'll
direct you further.
