Aes Encryption Key Generator
- In the beginning the two nodes will create a shared session key by using Deffie-Helman protocol, then one of them will genreate AES key and send it to the other node through the secure channel(i.e. DH protocol). So Could you please help in generating AES-256 bits in C# without using it to encrypt any plaintext. I just want the key itself.
- 13 days ago I am trying to do decryption in Node.js and encryption in C# with AES CBC 256. I have 16 byte key. I need 32 byte for AES CBC 256 method in Node.js. I tried using Buffer.alloc(32,16-byte-key).
