Using the Go SSH client
The golang.org/x/crypto/ssh package provides an SSH client that is compatible with SSH version 2—the latest version. The client will work with the OpenSSH servers and any other server that follows the SSH specifications. It supports the traditional client features such as subprocesses, port forwarding, and tunneling.
Authentication methods
Authentication is not just the first step but also the most critical. Improper authentication can lead to potential loss of confidentiality, integrity, and availability. A man-in-the-middle attack can occur if the remote server is not verified, leading to spying, manipulation, or blocking of data. Weak password authentication can be exploited by brute force attacks.
Three examples are provided here. The first example covers password authentication, which is common, but not recommended due to the low entropy and bit count of passwords compared with that of cryptographic keys. The second example demonstrates how to use a private key...
