One way to set the keysize is to use the -k option. losetup -e blowfish -k 256 /dev/loop0 SecureFile I'm using an assembler optimized version of aes and I can chose a keysize up to 256 bit. I don't know how big the keysize can be with blowfish (but I think it's also 256 bits). I think 3des is the most secure algorithm (because some mathematicians have recently discovered a method to describe the aes algorithm in a way that they can reduce the amount of possible keys for a brute force attack, and it is possible, that further investigations in the future could maybe break the code - sorry for my bad english, I hope you understand what I wanna say :), but 3des is very slow, so I'm using aes. I don't know anything about the security of twofish. cu lukas
