What this tool does

This tool generates cryptographically strong random strings for use as passwords, API keys, or VPN pre-shared keys. It utilizes the browser's Web Crypto API to ensure high entropy and performs all generation locally without transmitting data to a server.

When engineers use this

  • Creating strong, unique passwords for service accounts or database users.
  • Generating WireGuard pre-shared keys (PSKs) for VPN tunnel configuration.
  • Creating random UUIDs (v4) for database records or testing purposes.
  • Generating high-entropy strings for secret tokens or salts.

How to interpret the results

The output is a random string. Entropy refers to the unpredictability of the string; higher entropy makes brute-force attacks computationally infeasible.
