About Base32
Base32 encoding converts binary data into a text format using 32 ASCII characters (A-Z and 2-7).
Each character represents 5 bits of data, making it less efficient than Base64 but more human-readable.
Base32 is commonly used in TOTP (Time-based One-Time Password) systems and file naming.
