Our Client is looking at various options to encrypt the data and asked me the whether below approach is possible by using MQ exit.
App A (Sends Encrypt Data) ---> Qmgr 1 ---> Qmgr 2 ----> App B (Receives decrypted data from Qmgr 2)
Here the data should be decrypted at Qmgr 2 before App B receives it. I know MQ exits work in pairs but just want to confirm with you guys. |

Are you saying that App A does the encryption before putting the message at Qmgr 1?

| Yes, App A encrypts the data before sending it to Qmgr 1. |

But you want Qmgr 2, by way of an exit to decrypt?
I'm sure it can be done but for me, architecturally it doesn't fit. Either leave encryption / decryption to MQ and do it Qmgr to Qmgr or leave it to your apps so App B would do the encryption. Why mix it ?

I meant decryption, obviously.

Our long term approach is to have front end app to encrypt and backend app to decrypt but due to some time constraints it's not possible for backend app to change their functionality.
Can you tell me how this can be achieved?
Thank You!! |

Don't implement the App A encryption until App B decryption is ready. In the meantime use MQ's facilities.

Alternatively add an application that does nothing but pickup the message, decrypt it and make it ready for the destination application to pick up...
However you could just as well use encryption at the channel level ... but that would leave the data in clear at the qmgr level in transit.
Have fun

Is it possible by using API exit on MQGET? |

yes, why not, if the API exit is supported on your plattform....... but i'd go for the application solution
App A (Sends Encrypt Data) ---> Qmgr 1 ---> Qmgr 2 ----> App "decrypt" ---> App B

Is it something we need to have Data-Conversion exit? MQ is running on Windows 2003 32-bit and Sun Solaris 5.10. |

No exit if you use the app route. Just a decrypting app between the app queue and the receiving queue.
