module Base32

Overview

The Base32 module provides for the encoding (#encode, #hex_encode) and decoding (#decode, #decode_string, #hex_decode, #hex_decode_string) of binary data using a Base32 representation as defined in RFC 4648.

Examples

A simple encoding and decoding:

require "base32"

Base32.encode("Hello World!")        # => "JBSWY3DPEBLW64TMMQQQ===="
Base32.encode("Hello World!", false) # => "JBSWY3DPEBLW64TMMQQQ"

Base32.decode_string("JBSWY3DPEBLW64TMMQQQ====") # => "Hello World!"
Base32.decode_string("JBSWY3DPEBLW64TMMQQQ")     # => "Hello World!"
