 # perl-Crypt-DES
 
+The Crypt::DES module implements the Crypt::CBC interface.
+Do note that DES only uses 8 byte keys and only works on 8 byte data blocks.
+If you're intending to encrypt larger blocks or entire files, please use Crypt::CBC in conjunction with this module.
+Also note that the DES algorithm is, by today's standard, weak encryption.
+Crypt::Blowfish is highly recommended if you're interested in using strong encryption and a faster algorithm.
