These are the constants that define which encryption method is allowed to be used with the clients. Default value is encAny which means that all listed can be used - depends on client's selection. If you specify anything else, then wodSSHD will only list that particular encryption method when negotiating with the client. It is possible that client does not support the same encryption method, and connection could be closed.

You should know that client is the one who decides which method will be used in actual communication. Most of the newer clients prefer AES.

Note that encDES is not supported, and is listed only for compatibility with wodSSH and wodSFTP.
