Recommendations
- RSA often relies on SHA-1 signatures which are deprecated.
Private Key (PKCS#8)
Keep this file secret! Never share it.
Public Key
Share this with servers you want to access (authorized_keys).
Used to verify key integrity visually.
What does this tool do?
The SSH Key Generator allows you to create secure crypto keys for server authentication directly in your browser. No data leaves your device.
- Client-Side Generation: All keys are generated using the Web Crypto API. Your private keys never touch our servers.
- Multiple Formats: Support for RSA, ECDSA, Ed25519, OpenSSH, and PKCS#8 formats.
- Helper Tools: Includes key validation, format conversion, config generation, and pair matching.
Frequently Asked Questions
Is it safe to generate keys here?
Yes. The tool runs entirely in your browser using standard Web Cryto APIs. We cannot see or access your keys.
Which algorithm should I choose?
Ed25519 is the modern recommendation for speed and security. RSA 4096 is best for compatibility with legacy systems.
What is the difference between Public and Private keys?
The Private key is your secret credential (like a password) - never share it. The Public key is placed on servers you want to access.
