ROT-13 is a toy translator that can "encrypt" and "decrypt" file contents
using the ROT-13 algorithm. ROT-13 is a trivial algorithm that rotates each
alphabet by thirteen places. Thus, 'A' becomes 'N', 'B' becomes 'O', and
'Z' becomes 'M'.

It goes without saying that you shouldn't use this translator if you need
_real_ encryption (a future release of GlusterFS will have real encryption

so its an upcoming feature.

Why dont use GRE or ssh?
