🗝️ RSA Key Pair Generator

Generate random asymmetric RSA private and public PEM key pairs.

ℹ️ About RSA Key Pair Generator

The RSA Key Pair Generator creates the foundation for asymmetric encryption and digital signatures. Unlike symmetric encryption (like AES) which uses one key, RSA uses a Private Key for decrypting/signing and a Public Key for encrypting/verifying.

This tool generates standard PEM-formatted keys compatible with SSH, OpenSSL, and modern web servers. It is 100% client-side, meaning your keys are generated in your browser and are never transmitted to our server.

📖 How to use RSA Key Pair Generator

  1. 1. Choose your key strength: 2048 bits is standard, 4096 is for maximum security.
  2. 2. Click 'Run Tool' to generate your unique pair.
  3. 3. Copy both keys and save them to a secure location immediately.

Frequently Asked Questions

Which key do I share?

Only share the Public Key. The Private Key is your 'identity' and must never be shared or exposed.

What is 2048 vs 4096?

4096 bits is significantly harder to 'crack' but requires more CPU power to use. 2048 bits remains the industry standard for most secure connections today.

Can I use this for SSH?

Yes. These PEM keys can be converted or used directly for SSH authentication on Linux/Unix servers.
