Secure communications SSHv2 provider. SSHBRIDGE is an auxiliary program that allows your Windows applications to provide secure communications SSHv2 of extremely simple way. Today is very convenient to leave the network communication techniques based on plain text, such as TELNET protocol, for encrypted communications using the standard SSHv2. On the other hand, this new protocol is very complex to implement and provide this new functionality to your applications already developed is a job really hard to do.

SSHBRIDGE offers the possibility of using this new communication system without changing your programs. It runs as an auxiliary program that serves as a bridge TCP-SSH. If launched with the parameter "/silent", runs hidden and can not be handled by the user from the Windows programs bar. Otherwise displays a window showing the TCP and SSH listened ports and the number of active connections for each of them.

To better understand the mechanics of SSHBRIDGE below are described three different scenarios. In all cases your application and SSHBRIDGE reside on the same machine to prevent the insecure communication between the two will be exposed in the network:
1. Client application.
The goal is to let your client application to access a remote SSH server. It's necessary to define in the configuration file what unsafe port (TCP) will be used for the bridging function TCP -> SSH. SSHBRIDGE acts as a server for that TCP port. In the configuration you can define the parameters relative to the remote server for each local TCP port: remote IP, remote port (SSH), login and password. You can configure as many local TCP ports as necessary.

2. Server application.
Now we want a remote SSH client can communicate with your server application that listens an unsafe TCP port. For this purpose, SSHBRIDGE acts as an SSH server. In the configuration there is also a list of SSH listening ports indicating which local TCP ports must do the bridges SSH -> TCP. When accepting an SSH connection from a remote client, SSHBRIDGE makes a TCP connection to the local port obtained in the configuration, which is the one your application listens, making the twoway bridge between them.

3. SSH tunnel.
The job is to establish secure communication tunnels (SSH) for applications that are not safe. In this case we must have one SSHBRIDGE at each end of the communication for to redirect safely as many ports as desired. In the client application side is used the TCP -> SSH functionality and SSH -> TCP in the other end (server).

SSHBRIDGE not allow the execution of more than one instance simultaneously. If you launch the execution of the program, and there is already a running instance, the first closes automatically running the new operating. Your applications can modify the configuration of SSHBRIDGE and an easy way to apply the changes is to launch the execution of the program again. To close definitively the program you must call it whit the parameter "/close". This is especially useful if you use the hidden execution mode. It is also possible terminate the process from the Windows Task Manager.
