IconVault's RSA Key Generator creates RSA-2048 or RSA-4096 key pairs using the browser's WebCrypto API, the same cryptography built into modern browsers. The private key is exported as PKCS#8 PEM and the public key as SPKI PEM, ready to paste into SSH configs, JWT signing setups, TLS workflows and API authentication.

Because generation happens entirely on your device, your private keys are never transmitted, stored or logged anywhere. It is free with no signup. The honest note: this produces fresh random keys for development and personal use. For production systems, follow your organization's key management policy, protect private keys with file permissions and consider RSA-4096 for long-lived credentials.
