What is Base32 Encoding?

Base32 is an encoding scheme that represents binary data using 32 different characters: A-Z and 2-7. It is similar to Base64 but uses a smaller character set, making it more suitable for case-insensitive systems and environments where certain characters might be problematic. Base32 is commonly used in various applications including TOTP (Time-based One-Time Password) systems, DNS records, and other protocols that require case-insensitive encoding.

Common Use Cases

• TOTP systems: Two-factor authentication codes (Google Authenticator, etc.)
