base256(1) – Encode and decode data in base 256Command-line utility for encoding and decoding arbitrary binary data to and from easily typed words from the EFF autocomplete-friendly wordlist.
I actually wanted to use base 1296, because there are a total of 1296 words in the wordlist, but I soon realized that base 256 was far more convenient, since base 256 corresponds to a single whole byte.
base256 [-d | --decode]
base256 -h | --help
base256 -V | --version
Reads from stdin and writes to stdout.
-d, --decode Decode data (default action is to encode data).
-h, --help Show help and exit.
-V, --version Print version information and exit.
