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)
