RSA Key Generator

Generate RSA public/private key pairs for asymmetric encryption. Choose your key size and generate secure keys for encryption, digital signatures, and authentication.

Higher key sizes provide better security but take longer to generate and use.

About RSA Key Generation

What is RSA?

RSA is an asymmetric cryptographic algorithm that uses a pair of keys: a public key for encryption and a private key for decryption. It's widely used for secure communications.

Key Sizes

  • • 1024-bit: Legacy, not recommended
  • • 2048-bit: Current standard
  • • 4096-bit: High security applications

Security Notes

Keep your private key secure and never share it. The public key can be shared freely. Store keys in secure locations and consider using passphrases for additional protection.

Use Cases

  • • Secure communications
  • • Digital signatures
  • • SSL/TLS certificates
  • • Authentication systems
