The Solution is shared considering CAN I SHARE MY SOLUTIONS? Problem 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. Included below is a flag encoded as a hex string. Decode this back into bytes to get the flag. 63727970746f7b596f755f77696c6c5f62655f776f726b696e675f776974685f6865785f737472696e67735f615f6c6f747d Solution Python: ...

The Solution is shared considering CAN I SHARE MY SOLUTIONS? Problem 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. A B Output 0 0 0 0 1 1 1 0 1 1 1 0 For longer binary numbers we XOR bit by bit: 0110 ^ 1010 = 1100. We can XOR integers by first converting the integer from decimal to binary. We can XOR strings by first converting each character to the integer representing the Unicode character. ...

The Solution is shared considering CAN I SHARE MY SOLUTIONS? Problem ASCII is a 7-bit encoding standard which allows the representation of text using the integers 0-127. Using the below integer array, convert the numbers to their corresponding ASCII characters to obtain a flag. [99, 114, 121, 112, 116, 111, 123, 65, 83, 67, 73, 73, 95, 112, 114, 49, 110, 116, 52, 98, 108, 51, 125] Solution Python: ...
