Several clients have asked how to encrypt ODBC connections between Linux and IBM i to keep their Db2 data safe in transit. To encrypt ODBC data, IBM recommends the industry-standard TLS encryption protocol (the successor to SSL). Server side: When TLS is used, IBM i servers automatically assign a prestarted ODBC job named QZDASSINIT (the second “S” stands for “secure”) rather than the usual QZDASOINIT job. Client side: The Windows version of the IBM i ODBC driver starts encrypted mode when the SSL connection string keyword is specified. Linux users, however, need to use the secure tunnel (“stunnel”) package. IBM…
