About the Base32 Encode / Decode
Base32 encodes binary data using 32 case-insensitive characters. It is used in TOTP secret keys, some file formats and systems where case does not survive. It is more compact than hex but larger than Base64.
This tool follows the RFC 4648 alphabet and runs locally in your browser.
