Hybrid Encryption
Hybrid encryption is a cryptographic approach that combines the strengths of symmetric-key encryption and asymmetric-key encryption to securely transmit data. It uses asymmetric encryption (like RSA or ECC) to securely exchange a symmetric session key, which is then used with symmetric encryption (like AES) to encrypt the actual message. This method provides the efficiency of symmetric encryption for bulk data with the security and key management benefits of asymmetric encryption.
Developers should use hybrid encryption when building secure communication systems, such as in HTTPS/TLS protocols, secure messaging apps, or file encryption tools, as it offers a practical balance between performance and security. It is essential for scenarios requiring both confidentiality and efficient data transfer, like in web applications, VPNs, or encrypted storage solutions, where asymmetric encryption alone would be too slow for large data volumes.
