SSH Keypair Generator & Randomart Visualizer (Offline & Secure)

Generate secure SSH key pairs (Ed25519, RSA 4096, ECDSA) in your browser using WebCrypto API. Download .pub and .pem keys with OpenSSH Randomart visualizer.

How to use

  1. Select your desired algorithm (Ed25519 is recommended for modern servers).
  2. Enter a custom comment or email identity (e.g. user@devscratchpad).
  3. Copy or download your public key (id_ed25519.pub) and private key (PKCS#8 PEM).
  4. View the iconic OpenSSH Drunken Bishop Randomart ASCII art visualizer.

Technical Considerations

  • Zero server transmission ensures private keys never leave your machine memory.
  • OpenSSH wire format binary serialization done completely client-side.

100% Client-Side Privacy: This tool executes entirely within your browser's runtime environment. No payloads, tokens, or inputs are transmitted to external servers. Safe for offline usage.
