bashids
Pure Bash implementation of the hashid algorithm from Hashids.org
Usage
$ bashids -h
usage: bashids (-e|-d) [-s SALT -l MIN_LENGTH -a ALPHABET] (hashid|ints)
-e <encode>
-d <decode>
-s SALT (default: "")
-l MIN_LENGTH (default: 0)
-a ALPHABET (default: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890)
-h <help>Encoding
