Frequently asked questions

What is Base32 used for?

Base32 encodes binary data into a 32-character alphabet (A–Z and 2–7) that is case-insensitive and avoids ambiguous characters. It's used in TOTP secret keys, some URLs and file systems.

Which Base32 variant is this?

It uses the standard RFC 4648 alphabet with '=' padding — the same variant used by two-factor authentication secrets.
