Ssh1Context (Maverick Legacy - Client Assembly 1.7.64 API)

java.lang.Object
- com.maverick.ssh1.Ssh1Context

All Implemented Interfaces:

ExecutorServiceProvider, SshContext
```
public final class Ssh1Context
extends Object
implements SshContext
```
This class implements SshContext to provide SSH1 connection configuration through the SshConnector class. Currently this provides only one additional feature which is to set the preferred cipher type, however there is currently only one cipher algorithm supported so this feature is reserved for future use. To configure the SSH1 context use the following code:
SshConnector con = SshConnector.getInstance(); Ssh1Context context = (Ssh1Context) con.getContext(SshConnector.SSH1); context.setCipherType(Ssh1Context.CIPHER_3DES);
