UUID Information

What is a UUID?

A Universally Unique Identifier (UUID) is a 128-bit number used to identify information in computer systems. UUIDs are designed to be unique across space and time.

UUID Versions:

  • v1: Time-based with MAC address
  • v3: Name-based with MD5 hash
  • v4: Random (most common)
  • v5: Name-based with SHA-1 hash

Format:

xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx

Where M is version (1-5) and N has variant bits
