Flipping Bits

Bit flipping is an algorithmic manipulation of binary digits (bits). It performs logical negation on a single bit, or on each of several bits, switching state 0 to 1 and vice versa. Bit flipping is one of the popular bit manipulation algorithms, alongside AND, OR, XOR, NOT, and bit shifts. It’s usually used in cryptography algorithms to obfuscate messages.

def flipping_bit(n, base=8):
    bits = '{0:{fill}{base}b}'.format(n, fill='0', base=8)
    return int(''.join('1' if x == '0' else '0' for x in bits), 2)

def main():
    message = "This is secret message!!!"

    # Flipping the message
    flipping_bit_message = "".join(chr(flipping_bit(ord(x))) for x in message)
    print(flipping_bit_message)

    message = "".join(chr(flipping_bit(ord(x))) for x in flipping_bit_message)
    print(message)

if __name__ == '__main__':
    main()

In the flipping_bit function above, you can change the bit length to suit your needs.

Yeah, that’s flipping bit for playing with bit manipulation. Enjoy the read and thanks for coming in, goodnight.
