About RSA Encryption
RSA is an asymmetric cryptographic algorithm that uses a pair of keys (public and private) for encryption and decryption. It's widely used for secure data transmission and digital signatures.
Important Notes:
- Key Storage: Never share your private key with anyone
- Message Size: RSA can only encrypt small messages (max ~200 bytes for 2048-bit key)
- For Large Data: Use hybrid encryption (RSA for key exchange, AES for data)
- Security: Use at least 2048-bit keys for production use
