Base32 Encode / Decode
Encode text to Base32 or decode Base32 strings. RFC 4648 compliant.
What is Base32?
Base32 encoding represents binary data using a set of 32 characters (A-Z and 2-7). It's commonly used in TOTP/2FA secret keys, DNS, and other protocols where case-insensitivity is needed. Compared to Base64, Base32 is less compact but more human-friendly.
