About Base32 (RFC 4648)

Base32 encodes binary data using 32 printable ASCII characters: A–Z and 2–7. Every 5 bytes of input becomes 8 Base32 characters. Output is padded with = to a multiple of 8 characters. Base32 is case-insensitive and human-readable, making it useful for OTP seeds and similar applications.
