In short: If file and swap crypto is all you need, this package is a hassle
free replacement for international crypto patch and HVR's cryptoapi.
This package provides loadable Linux kernel module (loop.o) that has AES
cipher built-in. AES cipher can be used to encrypt local file systems and
disk partitions. For more information about compiling and using the driver,
see the README file in the package.
Features:
- GPL license.
- No source modifications to kernel. No patch hassles when you are upgrading
your kernel.
- Works with all recent 2.4, 2.2 and 2.0 kernels, including distro vendor
kernels. Encrypted disk images are compatible across all supported
kernels.
- AES cipher is used in CBC mode. Supports 128, 192 and 256 bit keys.
- Passwords hashed with SHA-256, SHA-384 or SHA-512.
- 512 byte based IV. IV is immune to variations in transfer size and does
not depend on file system block size.
- Device backed (partition backed) loop is capable of encrypting swap on 2.4
kernels.
Changes since previous release:
- Use newly added KERNELRELEASE in kernel 2.0 modules install path.
- build-initrd.sh shell script included to build /boot/initrd.gz that can be
used when root partition is encrypted.
- Default blocksize computation of file backed loop now shrinks blocksize
only if necessary. Previous default was hardcoded 1024.
- Add a workaround for 5 parameter do_generic_file_read()
- loop.c-2.4.original updated to Alan Cox's 2.4.13-ac2, with ifdefs so it
compiles on older kernels as well.
Of above changes only "workaround for 5 parameter do_generic_file_read()" is
a bugfix. Loop-AES claims to work with all stable kernels, yet previous
versions failed to compile on recent RedHat enhanced 2.4 kernels. This
version fixes such compile problems. No need to upgrade if you are using 2.2
or 2.0 kernels.
