Functions

xor_decode

xor_decode(data: bytes, key: bytes = XOR_KEY) -> bytes

XOR decode data with repeating key.

Since XOR is symmetric, this is the same as encoding.

Parameters:

Name	Type	Description	Default
data	bytes	Bytes to decode	required
key	bytes	XOR key bytes (defaults to π digits)	XOR_KEY

Returns:

Type	Description
bytes	XOR decoded bytes

Source code in flavor/utils/xor.py
