Cryptography in C and C++

const LINT operator ^ (const LINT& a, const LINT& b);

XOR, c = a ^ b;

const LINT operator | (const LINT& a, const LINT& b);

OR, c = a | b;

const LINT operator & (const LINT& a, const LINT& b);

AND, c = a & b;

const LINT operator << (const LINT& a, const int i);

left shift, b = a << i;

const LINT const int i);

right shift, b = a >> i;

const LINT shift (const LINT& a, const int i);

shift (left and right) by i bit positions, b = shift (a, i);
