The tilde operator in Python
...wos-complement representation of the integer are reversed (as in b <- b XOR 1 for each individual bit), and the result interpreted again as a twos-complement integer. So for integers, ~x is equivalent to (-x) - 1.
The reified form of the ~ operator is provided as operator.invert. To support th...

...e could just type it in as it is with the prefix 0b or 0B:
var binary = 0b1101000; // code for 104
console.log(binary); // prints 104

maximum value of int
...which is now set to maximum positive value.
We could also use a mask and xor but then we had to know the exact bitsize of the variable. With shifting in bits front, we don't have to know at any time how many bits the int has on machine or compiler nor need we include extra libraries.

How do I decode a base64 encoded string?

The m000493 method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd:
string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));
