Hash ID Generator
Generate hash IDs by encoding numeric IDs into short, unique, non-sequential strings. Hash IDs are perfect for obfuscating database IDs in URLs while maintaining the ability to decode them back to the original numbers.
Encode Number to Hash ID
Quick Examples
Hash IDs convert numeric IDs to short, obfuscated strings. This is useful for:
- Hiding sequential database IDs in URLs
- Creating shorter, more user-friendly identifiers
- Light obfuscation (not cryptographic security)
Note: Hash IDs are reversible and should not be used for security purposes.
FAQ
What are hash IDs used for?
Hash IDs are used to obfuscate sequential numeric database IDs in URLs, preventing users from guessing other record IDs and hiding information about your data volume. Unlike encryption, they are reversible without a key.
Are hash IDs secure?
Hash IDs provide obfuscation, not encryption. They make IDs non-obvious but should not be relied upon as a security measure. Anyone with the salt and alphabet can decode them. Use proper authorization for security.
Can I customize the hash ID output?
Yes, you can customize the minimum length, alphabet used, and salt string. The salt ensures your hash IDs are unique to your application and different from others using the same algorithm.
