I'm not sure what SSH is. But I know exactly what SSL is because I often use ssl cert myself. This is an encryption tool for websites. For example, to protect data transfer from the server to the user, you must use it.
SSL stands for Secure Sockets Layer. This is typically used to make sure that the connections that people may have on the internet are more secure. It will be useful to ensure that the security of people are safe when they check out certain websites. SSH is a bit different because while it also makes sure that the connection is more secure, it also provides encryption.
It makes sure that the data will be secure even from eavesdropping. People make it a point to install the SSH on a remote device because they know that this will help in improving the security of the network’s connection. People can usually decide between the two if they are creating a website.
