Get started in seconds — no signup required
The Base32 Encoder/Decoder converts binary data to and from Base32 encoding as defined by RFC 4648, using a 32-character alphabet of uppercase letters A through Z and digits 2 through 7. Base32 was designed for contexts requiring case-insensitive encoding — it is used in TOTP (Time-Based One-Time Password) secret keys for two-factor authentication, Tor v3 hidden service addresses, and certain DNS label encodings. Base32-encoded strings contain no ambiguous characters that could be confused visually, making them safe for manual transcription.
