Since the algorithm is designed for The bitstring module isn't a requirement, but it has lots of performant methods for turning input into and from bits into other forms, as well as manipulating them. Convert binary data to a line of ASCII characters in base64 coding. In the example, binaryString has a binary value that needs to be converted into an int. Click on the URL button, Enter URL and Submit. In this can since we are dealing with binary string, there the initializer which we will be using is bin. Decimal to binary Convert Binary String to Int in Python | FavTutor liberal towards whitespace) is also accessible using the This uses the CRC-CCITT polynomial This CRC is used in the binhex4 format.
