encrypt partitions

[Pau Amaro-Seoane]

hi,

I htink this is  a trivial question, but since this is newbies, there I go:

I have made two small separate partitions; one for my emails and the
other one for some very private files. The first partition is called
/correu and the second one /fitx_confg

I want the two of them encrypted. They are 2G and 100M in size. How
can I do it and how long does it take to encrypt/ decrypt them on
boot???

Cheers,

Pau

Some output follows.

(By the way, the 3600 RPM is a bug, I hope, this is supposed to be a 5400 RPM)
