About Base32
Base32 encoding converts binary data to ASCII text using 32 characters. The standard RFC 4648 alphabet uses A-Z and 2-7. Base32 is less space-efficient than Base64 but avoids case-sensitivity issues and excludes easily confused characters like 0, 1, 8, O, I, L.
What is Base32?
Base32 is an encoding scheme that represents binary data using a 32-character alphabet (A-Z and 2-7).
It's commonly used in applications where case-insensitivity is important, such as DNS names, file systems, and two-factor authentication (TOTP) secret keys.
