Hi everybody, I'm using the cryptoapi since more than a year (2.4.4).... Now I tried to move to newer kernel (2.4.17) and I'm not able to setup a loop device with the new kernel..... I patched the 2.4.17 kernel with patch-int-2.4.17.0.gz, loop-jari-2.4.16.0.patch and everything compiled fine... I build the util-linux-2.11n with the new patches and everything compiled fine.... then I loaded all modules cryptoapi,cipers, digest, etc.... and tried: # dd if=/dev/urandom of=file bs=1024k count=100 # losetup -e twofish /dev/loop0 file Available keysizes (bits): 128 192 256 # Keysize: 256 # Password : # Password : The cipher does not exist, or a cipher module needs to be loaded into the kernel ioctl: LOOP_SET_STATUS: Invalid argument and thats it.... with every cipher. Is there anybody out there who can help me ???? Any comment is welcome. so long -- Michael Rietz e-mail: rietz@su3.de MR1574-RIPE - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
