What is SSH Key Generator?
SSH Key Generator creates a public and private key pair using the browser Web Crypto API. The keys are exported as PEM text that can be stored or converted for SSH use.
How It Works
The browser generates an RSA or ECDSA key pair. The private key is exported in PKCS#8 and the public key in SPKI, then both are encoded as PEM blocks with standard headers.
Common Use Cases
- Creating development key pairs without a command line
- Generating keys on a machine without OpenSSH tools
- Learning how public and private keys relate
- Producing PEM keys for local testing
Technical Details
Uses crypto.subtle.generateKey with RSA-OAEP or ECDSA P-256 and exports PKCS#8 and SPKI. Keys are generated in memory and never uploaded.
