Convert number between different bases (decimal, hexadecimal, binary, octal, base64, ) Roman numeral The ASCII table assigns a unique numeric code to each character, but this code (between 0 and 127) can be written in multiple ways depending on the needs. Our assumption was correct. I create my recipe in which first element is "from hex" and second element is "To dec" and my input is: 0x1cda3c000, in decimal it is 7745028096, but CyberChef reports "28 There are many use cases for cyberchef, which include malware investigations, digital forensics, testing yara rules, defeating obfuscated malware, and many more.
