Question Cryptographic Options for the Kernel


I understand the fact that there are different cryptographic algorithms and the like, but one thing I have never understood are all the available ones when compiling the kernel. I mean, how are they really useful in terms of the kernel?
Also, I would like to know how to test out the different algorithms... Do I need to modify gpg, or what?

Just curious...

they are not really useful to the kernel .. but they are useful to modules, or parts of the kernel that need cryptography support (like for using the cryptoloop)

gpg does not use crypto api (the kernel crypto stuff) it uses its own encryption library's

crypto-loops is depreciated, use dm-crypt.

yeah....

dm-crypt is in the newish 2.6 series.. from 2.6.4 i think.

its in MultiDevice / RAID area.
you dont have to enable raid to use it.. its just put there because it can be very usefull with RAID.

just looked.. its in

Device-Drivers -> Multi-Device Support

oh, so thats why i never saw it when i made my 2.6 kernel

thanks.... ill be sure to give it a try next time i remake the kernel (i have a partition that it would be useful for ... right now its only protected by the fact that no one around this house knows how to use a computer )
