Why we built this tool

When testing security tools, sending sensitive data like passwords or tokens to a remote server defeats the purpose. We built this tool to run entirely in your browser using the Web Crypto API — your data never leaves your device.

About Bcrypt ジェネレーター: what you should know

DevOps engineers and security-conscious developers who rotate secrets and verify integrity as part of their daily workflow. Whether you are checking a file checksum, generating an API key, or validating a token, doing it locally avoids sending sensitive data through an external service.

Key features

  • Cryptographically Secure Output — Uses the Web Crypto API under the hood, so generated values have real entropy and are suitable for production use — not weak Math.random() output.
  • No Server, No Storage — Every operation runs entirely in your browser. Secrets, hashes, and tokens are never transmitted or logged by any third-party service.
  • Batch-Friendly Workflow — Process multiple inputs at once when you need more than one value. Each result is independent so you can copy what you need without confusion.

Common use cases

  • Building Lookup Tables for Testing — Generate a batch of hashes or tokens to populate a test database. Each value is independent, so tests do not interfere with each other.
  • Verifying Existing Data — Check whether an existing hash or token matches what you expect. Useful for auditing stored credentials or debugging auth failures.

What hash algorithms are supported for checksum generation?

ToolPure supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hash algorithms. All hashing is performed locally using the Web Crypto API, ensuring your data never leaves your browser.

Can I generate and validate JWT tokens?

Yes, you can decode JWT tokens to inspect header and payload, and generate new JWT tokens with custom claims. The tool supports HS256, HS384, and HS512 signing algorithms.

Are password generation tools truly random?

Yes, password generation uses the Web Crypto API getRandomValues() function, which provides cryptographically secure random numbers. Generated passwords are not stored or transmitted anywhere.
