About

Hex (Hexadecimal) encoding represents binary data using base-16 notation (0-9, a-f). Hex IDs are generated from random bytes and encoded in hexadecimal format. They're commonly used for unique identifiers, API keys, and tokens. A 16-byte random value produces a 32-character hex string. Hexadecimal is the most common way to represent binary data in human-readable form and is widely used in programming, debugging, and data representation.

Use Cases

  • •API keys and tokens
  • •Unique identifiers
  • •Cryptographic keys representation
  • •Debugging and logging
  • •Color codes (CSS hex colors)
  • •Memory addresses and pointers
  • •General-purpose binary data representation
