How to Generate an RSA Key Pair
Step-by-step guide to creating a public and private RSA key pair for encryption and signing using the DevHexLab RSA Key Generator.
Tool Used
RSA Key Generator
1
Open the RSA Key Generator
Navigate to /tools/security/rsa-key-generator.
2
Choose the key size
Select 2048-bit for general use or 4096-bit for higher security requirements. Larger keys are more secure but slower to compute.
3
Generate
Click Generate. The tool produces a PEM-encoded public key and a PEM-encoded private key entirely in your browser.
4
Download both keys
Download the private key and store it securely. Share only the public key. Never expose the private key.
All done!
You are ready to use RSA Key Generator like a pro.
