Dear all: Today, I payed attention to linux-crypto for the first time and Im amazed on how easy is to make it run! (at least, XOR encryption, see below) I found a problem: debian's losetup version is 2.11z. After some "LOOP_SET_STATUS: Invalid argument" errors, when trying to use 'twofish' (everything worked as expected if I use XOR), I found the following note on the manual: BUGS: CAST, DES, RC5 and Twofish are currently broken and cannot be used. so, I downloaded 2.12pre and on the manual it says: -e encryption enable data encryption. The following keywords are recognized: NONE use no encryption (default). XOR use a simple XOR encryption. DES use DES encryption. DES encryption is only available if the optional DES package has been added to the kernel. DES encryption uses an additional start value that is used to protect passwords against dictionary attacks. So: how do I use twofish encryption? on 2.11z is buggy and 2.12pre doesn't has the option to do it! - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
