What is UUID Validator?

UUID Validator is an efficient tool that allows you to verify multiple UUIDs (Universally Unique Identifiers) simultaneously. It helps developers and data engineers quickly check the validity and version (such as UUIDv1, UUIDv4) of UUIDs they work with daily, enabling early detection of data integrity issues. This tool significantly streamlines verification tasks in various development scenarios including database operations, API testing, and log analysis.

UUID Basics

A UUID is a 128-bit (16-byte) identifier widely used to ensure uniqueness in distributed systems. The main versions include:

  • UUIDv1: Time-based (derived from MAC address and timestamp)
  • UUIDv4: Randomly generated (most commonly used)
  • UUIDv5: Name-based (using SHA-1 hash)
  • Other versions: v2 (DCE security), v3 (name-based using MD5), v6-v8 (newer versions)

Features and Capabilities

  • Multiple UUID Validation: Validate multiple UUIDs at once using line breaks as separators, saving time when processing large data sets
  • Version Identification: Automatically identify the version of each UUID (v1, v4, etc.), helping you understand the origin of your data
  • Visual Result Display: View validation results in an easy-to-read table format with color-coded validity indicators for intuitive verification
  • Asynchronous Processing: Process large numbers of UUIDs quickly with immediate feedback on results

How to Use the UUID Validator

Basic Operation Steps

  1. Enter UUIDs
    Input the UUIDs you want to validate into the text area. Multiple UUIDs can be entered with each UUID on a separate line.

  2. Click the "Validate" Button
    After entering your UUIDs, click the "Validate" button to process them.
  3. Check the Validation Results
    The results table displays the following information:
    • UUID: The UUID string you entered
    • Validity: The validation result showing "Valid" or "Invalid"
    • Version: For valid UUIDs, the version number (1, 4, etc.)
  4. Make Adjustments if Necessary
    If any UUIDs are found to be invalid, you can correct them and validate again.

Use Cases

  • Database Development: Validate UUIDs used as primary keys or unique identifiers in databases
  • API Testing: Verify the validity of UUIDs in API requests and responses
  • Log Analysis: Validate and categorize UUIDs recorded in system logs
  • Data Migration: Ensure ID accuracy when transferring data between different systems
  • Troubleshooting: Identify the source of ID-related issues when problems occur

Technical Details

The UUID Validator performs validation based on strict RFC4122 specifications, implementing appropriate structural checks for each version of UUID. Invalid UUIDs are clearly identified, providing feedback for correction.
