TRANSMIT encryption exit — INMXZ03R or INMXZ03

The TRANSMIT encryption exit (INMXZ03R or INMXZ03) receives control immediately after TRANSMIT prompts the user for REPRO command options for enciphering the data to be transmitted. (It is invoked only once, regardless of the number of people to whom the data is being sent.)

Note: If RACF® is installed, and if your installation is using security labels, this exit receives control after INMXZ21R. The encryption exit can:

Examine and, if appropriate, change the ENCIPHER options the user specifies. If TRANSMIT is to do the enciphering, it builds the REPRO command after the exit returns, using the changes the exit makes.
Invoke encryption processing itself. The exit receives all the control and ddnames that TRANSMIT uses for encryption processing.
Decide that encryption is not necessary, and prevent TRANSMIT from doing it.
