Another pastebin moment for the public: My "nonceJuicer" open source for Nekow42 Zarf's "Arcfour strong Encryption"(http://wiki.secondlife.com/wiki/ARCFOUR_Strong_Encryption_Implementation)

My juicer adds the nonce function that was missing from the examples.

Grab this script for encoding encryption out: http://pastebin.com/nmvYhr8L "red_out.lsl"
and this script for decoding encryption in: http://pastebin.com/17LJxadP "green_in.lsl"

Put them in their own prim (completely separate) each, and make sure both prims are reset at the same time after compiling.
