Canumb aims to crunch data on various forms and turn them into something meaningful. A variety of inputs are currently supported, such as different number base conversions (decimal to hexadecimal, binary to hexadecimal, octal to decimal, etc.) and various encoded formats (a base64 encoder decoder and a URI encoder decoder). It's built to allow for extension when the future demands other input formats be crunched.
base85 implements Base85 encoding and decoding for Node.js. It supports the most commonly known specifications; ascii85, zeromq, and ipv6 (RFC1924). It is excellent for encoding arbitrary (possibly binary) data into a text string which can easily be copy-pasted to source code files or e-mails.
