SSH Key Pair Generator

About SSH Key Pair Generator

How to use SSH Key Pair Generator

1. Select the key size. Choose 2048 bits for general use, or 4096 bits when higher security is required. Note that 4096-bit keys may take a few seconds to generate.
2. Click the 'Generate Key Pair' button to instantly create an RSA key pair within your browser. All processing is done via the Web Crypto API and no data is ever sent externally.
3. The generated private key and public key are displayed in PEM format. Use the 'Copy' button to copy each key to your clipboard, or the 'Download' button to save it as a file.
4. The info card shows the algorithm name, key size, SHA-256 fingerprint, and generation timestamp. The fingerprint can be used for key identification and verification.

Benefits of SSH Key Pair Generator

• Zero risk of private key leakage with fully in-browser processing: SSH private keys are among the most sensitive credentials you manage. This tool uses the Web Crypto API to generate keys entirely within your browser, making it physically impossible for private keys to be transmitted over the network.
• No command line required — easy for everyone: Traditional SSH key generation with ssh-keygen can be intimidating for users unfamiliar with terminal operations. With this tool, simply select a key size and click a button to get PEM-formatted key pairs and fingerprints automatically.
• Automatic SHA-256 fingerprint calculation: The tool automatically computes the SHA-256 hash of the generated public key, displayed in ssh-keygen-compatible Base64 format for immediate use in server registration and key verification.
