franbac v1.3.0

franbac 🥓

helps encode/decode strings that use two different characters to represent A's and B's. more info about the bacon cipher here

it will try to decode with letter 1 = A and letter 2 = A. if one of those decoded texts results in an invalid plaintext, it will discard it. it will try with the default alphabet and the alternate alphabet (both are in that wikipedia page).
