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.

How to Use

Generator

  1. Select the "Generator" Tab.
  2. Choose a Version: Select the UUID version you need from the dropdown. v4 is the most common choice for general-purpose unique IDs.
  3. Configure:
    • Set the Quantity of UUIDs to generate.
    • If you chose v3 or v5, you must also provide a Namespace UUID and a Name.
  4. Generate: Click the "Generate" button. A new list of UUIDs will appear.
  5. Copy: Copy individual UUIDs or the entire list using the dedicated buttons.

Validator

  1. Select the "Validator" Tab.
  2. Enter a UUID: Paste the UUID string you want to validate into the input field.
  3. Click Validate: Press the "Validate" button.
  4. Review the Result: An alert will appear, telling you if the string is a Valid UUID or an Invalid UUID.
