About Base32 Encoding
What is Base32?
Base32 is a binary-to-text encoding scheme that uses a 32-character alphabet to represent binary data. It's commonly used in 2FA (Two-Factor Authentication) systems, TOTP secrets, and applications where case-insensitive encoding is required.
Common Use Cases
- • 2FA and TOTP secret keys
- • Legacy authentication protocols
- • Case-insensitive data encoding
- • Git object names and references
- • Network protocols and APIs
