Question: In our application we have the need to encrypt a 19 character simple string value. When running through the sample test program I found that the resulting encrypted string varied in size from at least 44 to 64 characters depending on the encoding type parameter.

Most email clients (Mozilla Thunderbird, Eudora, etc.) are not capable of displaying MS-Word documents directly. (I’m not sure if Outlook does, I’ve never tested it…) Therefore, you would want to save your MS-Word […]

SSH Port Forwarding (or tunneling) allows you to tunnel any TCP connection through an SSH server. For example, consider a database connection: A direct TCP connection: DbClient <—-TCP—-> DbServer An SSH tunneled connection: DbClient <—-TCP—-> SshClient <====SSH====> SshServer <—-TCP—-> DbServer In a tunneled connection, the application connects through an SshClient to an SSH server and starts a direct-tcpip channel, specifying […]
