Cryptography - Key Exchange Algorithm

Card Puncher Data Processing


The goal of a key exchange algorithm is to permit to distribute Key on a secure way between two parties.


The two most known key exchange algorithm are by order of important:

But they are more. Below is a Winscp options snapshot that shows their standard list.
