Encoding prevents the data from getting corrupted when it is transferred or processed through a text-only system. It's as simple as: Convert. This snippet first converts the bytes to a NumPy array with an unsigned 8-bit integer data type. The answer would probably be, a base64 string will take more bytes than if the unencoded data was sent as raw bytes. b64decode (encoded_signature) Not sure this is the correct way to convert byte string to string. It then calls the base64. If it is an object conforming to the buffer interface, a read-only buffer of the object will be used to initialize the bytes array. Additionally, you'll practice this knowledge by coding a few fun examples. It is important to remember that the size of Base64 encoded files increases by 33%.
