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.
