# Base32

**Base32** is a binary-to-text encoding scheme that represents binary data as a sequence of 32 characters (letters and numbers).

## How it works

Base32 encoding works by dividing the binary data into 5-bit blocks and then representing each block as a character in a predefined set of 32 characters.

The symbol "=" is used as padding.

This results in a representation that is more compact than the original binary data, making it easier to store or transmit.

import base64

data = b"SomeData"

encoded = base64.b32encode(data)

decoded = base64.b32decode(encoded)
```
