A Developer's Guide to the UUID/GUID Generator & Validator
The UUID/GUID Generator & Validator is an essential tool for creating and validating Universally Unique Identifiers (GUIDs). These are 128-bit numbers used to uniquely identify information in computer systems.
Generator Features
- Multiple UUID Versions: Generate UUIDs using different standard versions:
- Version 1 (Timestamp): Creates a UUID based on the current timestamp and the host's MAC address (or a random node if not available).
- Version 4 (Random): The most common type, generated from cryptographically strong random numbers.
- Version 3 (MD5) & Version 5 (SHA-1): Name-based UUIDs that are generated consistently from a given "namespace" UUID and a "name" string.
- Bulk Generation: Create multiple UUIDs at once by specifying the quantity.
- Easy Copying:
- Copy a single UUID with one click.
- Copy the entire list of generated UUIDs to your clipboard.
Validator Features
- Simple Validation: Paste any string into the validator to instantly check if it's a structurally valid UUID.
