This class is a descendant of TElSSHClass.
TElSSHClient is used to add SSH support to client side of TCP connection
(the client side is the side which initiates connection). To initiate

To transfer data over the secure SSH connection the Tunnel objects are used. Each tunnel represents a type of logical connection ( Shell, Command, Subsystem, TCP-IP local forwarding, TCP-IP remote forwarding, X11 forwarding). The Tunnel object may create a number of TunnelConnection class instances. Each TunnelConnection carries single logical connection. For example, if you want to forward the connections, accepted by remote port to your machine, you have to create one instance of TElRemotePortForwardSSHTunnel, and for each accepted connection on the server side one instance of TElSSHTunnelConnection class will be created.
By default, TElSSHClient is allowed to work using both SSH1 and SSH2 versions and all encryption, public key, key exchange and MAC algorithms. You can disable or enable some of versions using Versions property and disable or enable security properties with EncryptionAlgorithms, PublicKeyAlgorithms, MacAlgorithms, KexAlgorithms and CompressionAlgorithms properties.
When connection is established, connection version can be read from Version property.
This component supports FIPS compliant mode. For more information, read the corresponding article.
