a particularly psychotic school friend of mine began sending me encoded messages the other day and demanded that i decode them. naturally, i did. being the geek that i am, i not only decoded them, but also made two scripts that would encode and decode for me. first i did a letter shift decoder, then a caesar box decoder, and then a letter reverse decoder. these were all ok and worked just fine but they were all bland and unoriginal.

so my friend(code name vinnie) came up with his own code. it works by starting with a random letter and then adding new letters so that the sum of the two letters equals the encoded number. for example ondklty would be o+n=b, n+d=r, d+k=o, k+l=w, l+t=e, t+y=r to read the encoded message “brower�. i made both an encoder and a decoder for this technique. i also made the space character the 27 letter to allow for spaces. any other characters will mess up the encoder/decoder.

you can see the encoder and decoder.
