WebDec 23, 2024 · When we encrypt something the resulting ciphertext commonly has bytes which are not printable ASCII characters. If we want to share our encrypted data, it's common to encode it into something more user-friendly and portable across different systems. Hexadecimal can be used in such a way to represent ASCII strings. WebJan 27, 2024 · It's thus very likely that the first character of the flag you're trying to retrieve is c, which means that the XOR key must be the ASCII value of c (0x63) XORed with the first character of the ciphertext (0x73).
