#FAQ
What is Base32 encoding? ▾
Base32 is a binary-to-text encoding that uses a 32-character alphabet (A-Z and 2-7). It is case-insensitive and commonly used in TOTP/2FA secret keys and DNS-compatible encodings.
How does Base32 differ from Base64? ▾
Base32 uses fewer characters (32 vs 64) making it case-insensitive and suitable for contexts where case sensitivity is problematic, but it produces longer output than Base64.
