To whom it shall concern: I attempted to install and use the Mandrake 8.1 RPMs for the crypto API and ran into a few issues I am curious about. 1) Are you supposed to get error messages like "already installed" when doing this? 2) I read the documentation readme that came with the RPMs I downloaded, but what is the name of the file that has the documentation in the "Doc" directory in /usr/src/linux? 3) The Binary RPMs (of the kernel) were not usable to me, as I have my root partition using ReiserFS and these binaries were built absent that module. However, now that I have to rebuild the kernel (which I don't mind), how do I verify that all the crypto patches are in place in the source tree?

You should use a full keylength bits' key with full entropy. If you do this, you don't need a seed. (and even if you did, 128 _bits_ would be more than enough). Also, the seed need not be secret (and can't be). It must be random, though, so you'd better use /dev/random instead of urandom...
