FAQ
Common questions and answers about this topic.
What is an RSA key pair?
An RSA key pair consists of a public key for encryption and a private key for decryption. It is the foundation of public-key cryptography used in TLS, SSH, and digital signatures.
What key sizes are supported?
Common key sizes include 2048 and 4096 bits. Larger keys provide stronger security but are slower to generate.
Is it safe to generate keys in the browser?
The keys are generated entirely in your browser and never leave your device. However, for production security-critical applications, consider using dedicated key management tools.
Is my data sent to any server?
No, RSA key generation happens entirely in your browser. Your key pair is generated locally with JavaScript and the private key never leaves your device.
