π About Hex Encoding
Hexadecimal (hex) is a base-16 notation commonly used to display binary data. Each byte (8 bits) is represented by two hex characters (0-9, A-F), ranging from 00 to FF.
Common Use Cases
1. Hash Values: MD5, SHA-1, SHA-256 and other hash algorithms usually output hex.
2. Network Debugging: Tools like Wireshark display network packets in hex.
3. Binary File Viewing: Hex editors are used to view and edit binary files.
4. Color Codes: HTML/CSS colors such as #FF5733 are hex representations.
