 * CWE: 319 Cleartext Transmission of Sensitive Information
 * BadSource: connect_tcp Read password using an outbound tcp connection
 * GoodSource: Set password to a hardcoded value (one that was not sent over the network)
 * Sinks: kerberosKey
 *    GoodSink: Decrypt password before using in KerberosKey()
 *    BadSink : Use password directly in KerberosKey()
 * Flow Variant: 51 Data flow: data passed as an argument from one function to another in different classes in the same package
