WebMay 13, 2016 · There is also a nice formula giving solutions for quadratic residues modulo n: x = a ( p − 1) ( q − 1) + 4 8 mod n. As usual, it is sufficient to verify it modulo p and modulo q separately.

I don’t usually see this written as “2/5”, but it makes sense: the number 30 will behave exactly like 2/5 does when it comes to addition and multiplication mod 37.

Webcrypto {3nc0d3_d3c0d3_3nc0d3} XOR Starter - Points: 10 XOR is a bitwise operator which returns 0 if the bits are the same, and 1 otherwise. In textbooks the XOR operator is denoted by ⊕, but in most challenges and programming languages you will see the caret ^ used instead. For binary strings we XOR bit by bit: b'0110' ^ b'1010' = b'1100' .
