Cipher 168 or 256 Bit ?

[wasabi]

hi!

when i connect with flashfxp (v3.0.2.1044) i get this msg in status window:

[R] SSL encrypted session using cipher DHE-RSA-AES256-SHA (256 bits)

so far, so good.
but... sometimes it looks like this (same server):

[R] SSL encrypted session using cipher EDH-RSA-DES-CBC3-SHA (168 bits)


maybe somebody can tell the difference?
i always thought that AES256 was one of the strongest algos...
why does it change?
