[xSRTsect]

 A few bricks put altoghether. Also I would like to know a few things: The author said this was a modification of a known pk encryption. I would like to know which.

 

 

EDIT: Because afaik, the set key process is clearly Rc4 based , and the final encryption stage seems to be a rc5 variant.
