sorry Crypto++ guys, but after I spend 2 hours by trying to figure out
how everything works ( documentation sucks, sorry ) and after this
when I got the linker error, I sad that's enough for me and started to
look around for another crypt library.
After a few google I found the Botan library http://botan.randombit.net/
I spent 5 mins to read its docs, then solved my problem in another 10
mins.
so, what I want to say to you Naja, you may want to look at Botan
library too.
Have fun.
