Base32 Encoder & Decoder
Encode and decode Base32 strings — used in TOTP secrets, DNS records, and case-insensitive identifiers.
What is Base32 Encoder & Decoder?
Base32 encodes binary data using 32 alphanumeric characters (A-Z, 2-7). Unlike Base64, it's case-insensitive and avoids visually-confusable characters (0/O, 1/I/l) — making it suitable for handwritten or spoken transmission. Most commonly used in 2FA secret keys and DNS records.
