Re: [suse-security] How do I encypt the swap (partition[s]) under SuSE 9.3 Prof ?



Hi Christiph,
first, it`s a good thing to encrypt swap.
Cause you  never know what is swaped out.

There was an Article about this in Linux-magazine
some time ago. (Sorry, you` gotta search on youre own. ;-( )


The way was to format swap every boottime with a new
generated encryption Key and store the key only in
the Kernel.
So, after shutdown, decryption of swap is impossible.

Do not store the Key anywhere unencrypted.
Use a howto encrypt Filesystems HOWTO.

And don`t use suspend to harddisk ;-))
