RSA Key Information

Key Sizes:
  • • 1024-bit: Fast but weak (deprecated)
  • • 2048-bit: Standard for most applications
  • • 3072-bit: High security level
  • • 4096-bit: Maximum security (slower)
Public Key:

Can be shared freely. Used to encrypt data and verify digital signatures.

Private Key:

Must be kept secret. Used to decrypt data and create digital signatures.

Common Uses:
  • • SSL/TLS certificates
  • • SSH authentication
  • • Digital signatures
  • • Email encryption (PGP)
