How A1Z26 works
A1Z26 is a simple substitution cipher where each letter is replaced by its position in the alphabet: A=1, B=2, … Z=26. Words are separated by a delimiter (default: slash), and individual letter numbers are separated by a configurable separator. It's commonly seen in puzzles, escape rooms, and geocaching.
