Blowfish and Cast have variable key lengths. Does a larger key length equal higher security, shorter key length lower security?
Taken from the OpenBsd-Misc mailing list: Yes, to some extend; the point with variable key-length ciphers is that in the future (when Pentium17 comes out, which can crack DES in less time than you need to ping 127.0.0.1) you won’t have to design a new algorithm. With today’s technology, 128 bits are considered sufficient for the next 10 years. The difference between 256 and 300 bits is just theoretical đŸ™‚ —Angelos D. Keromytis
