What is Base32 Encoding?

Base32 is an encoding scheme based on 32 printable characters (A-Z and 2-7), used to convert binary data into ASCII string format. It is an encoding method defined by the RFC4648 standard and is designed for scenarios where special characters need to be avoided.

Characteristics of Base32 Encoding

• Uses 32 characters (A-Z, 2-7), excluding digits 0 and 1 to avoid confusion with letters O and I
• Encoded text contains only uppercase letters and some digits, no special characters
• Uses = sign as padding to ensure output length is a multiple of 8
• Encoding efficiency is about 130% of the original data (every 5 bytes of data encoded into 8 bytes of text)
• Has error correction capability, some errors can be detected through charset characteristics
