Below is A1Z26 encoder/decoder. A1Z26 is very simple direct substitution cypher, where each alphabet letter is replaced by its number in the alphabet.
Here all letters are set to lowercase, english alphabet is used and all non-alphabet symbols are not transformed. In decoding all numbers (from 1 to 26) should be separated by any non-digit symbol (dash, space, etc.)
