file and image encryption?

Bump ^_^

Is simple XOR. ^_^ i have a system better than that... and once showoff them some guys... Well, if someone donate me some unique sprites ^_^ i can make it detailed and for public

ps. it's all about content protection and crypto. I already has solution, and my own low-level libraries for package(!) OTClient content, also obfuscation & etc... but release all of this for public...for free... what is my profit or motivation?
UPDATE:

*.pkg - is archive with custom (my own) implementation of CAST-256 Algorithm + huffman code algorithm. Winrar can only see it contents, but no ways to unpack them without special packager. Due 3 things: 1) Password larger than you can type on input for common archivers. 2)Password - is symbols, impossible to type on keyboard. 3)No one common archivers has algorithms to unpack them due to custom algorithms.



Ps. it also can pack SPR and Dat files without ways to decode them outside by various OTTools. (Needless to say, you may see VMProtect inside. Yeah, them uses my custom scripts for protect under VMProtect. just anti-reverse things.)
Well, what is your offer? (i no need moneys or something like that.... i wanna spriteeessss! Or you may found spriter for me and draw it. Rly need many sprites for re-draw all things in tibia. Gimme maybe... 4+ biomes (ground, tiles, buildings, trees, decorations) or something equals, and ill give you full source code for protection + bonus. Imho - fair exchange enough).
