WebHexadecimal Codes can represent ASCII, UTF-8, or more advanced encoding schemes. They can also represent the output of Hash functions or modern crypto algorithms like RSA, AES, etc. Hexadecimal codes only use the digits 0-9 and letters A-F. Use the Hex Analysis Tool to find out more about your hexadecimal codes. Binary Codes Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. Symmetric key ciphers are implemented as either block ciphers or stream ciphers. …
