[syslog-ng]encryption or hashing implemented?

[Blaise St-Laurent]

I've noticed passing mention to this functionality, and i've not been able
to see it implemented or documented anywhere else. A quick grep of the
source reveals nothing of hashing, and a "not implmented yet" for
encryption. This was in 1.4.17. is this functionality to be found in the 1.5
branch?

If not, could someone point me towards the files i could modify to add
hashing? Thanks.

Thanks in advance,

Blaise St-Laurent
