SSID Generator is a Node.js module that provides a secure and efficient way to generate short IDs, suitable for various use cases such as unique identifiers in databases, session IDs, URL shorteners, etc.
- Generates short IDs using a secure algorithm.
- Customizable length for generated IDs.
- Supports a wide range of characters, making IDs URL-friendly.
- Generate short IDs with prefix and suffix
- Generate short IDs with timestamps
- Ensures uniqueness of generated IDs, even in high-demand scenarios.
- Suitable for applications where security and uniqueness are critical.
- Optionally includes or excludes symbols based on your requirements.
You can install the Secure Short ID Generator module via npm:
