WebMay 18, 2024 · There are multiple ways to do symmetric encryption. The two most popular ones are block ciphers and stream ciphers. So stream ciphers are a subset of symmetric ciphers. AES and 3DES are block ciphers, not stream ciphers. But if you use them (or any other block cipher) in CTR mode, you can create a stream cipher out of them. WebSymmetric key algorithms are well accepted in the modern communication network. The main advantage of symmetric key cryptography is that the key management is very simple. Only one key is used for both encryption as well as for decryption purpose. There are many methods of implementing symmetric key.
