About This Tool

This SSH key analyzer generates fingerprints from SSH public keys and converts between different SSH key formats including OpenSSH, PEM, and PKCS8. It is a valuable tool for system administrators, DevOps engineers, and developers who need to verify key identities or transform keys for use across different systems. The tool processes keys entirely in the browser, ensuring your sensitive cryptographic material never leaves your device.

How to Use

  1. Paste your SSH public key into the input field
  2. View the generated fingerprint in MD5 and SHA256 formats
  3. Select a target format to convert your key between OpenSSH, PEM, or other formats
  4. Copy the fingerprint or converted key for use in server configuration or verification
