About Base32 Encoder/Decoder
Base32 Encoder/Decoder converts text to Base32 encoding and decodes Base32 strings back to text. Supports the standard RFC 4648 Base32 alphabet (A-Z, 2-7) and Base32Hex alphabet (0-9, A-V).
Base32 is used in TOTP authenticator apps (Google Authenticator, Authy) for the shared secret key, in RFC 3548-compliant data encoding, and where data needs to be case-insensitive and human-readable without ambiguous characters.
If you're setting up two-factor authentication or working with TOTP secrets, this tool lets you inspect the raw Base32-encoded key.
