Hi
I have a scenario like, my MQ network is DQM implementation. In one of the message we pass "PASSWORD" to remote queue manager. This password I want to encrypt at source qmgr and decrypt at remote(partner) queue manager.
I would like to know , is there any default mechanism or any work around for this.
I am using MQ 5.2 not MQ 5.3. And one more thing, Can I write channel exits using Java ???
Many Many Advanced Thanks

Here's my $0.02:
1) In Unix, it is easy to encrypt a message - use the encrypt function. According to the man page, decyrption is one of those "Feds-only" thing that may or may not be available.
2) AFAIK, (if you're using Unix), the exit must be compiled and linked as a shared object - which, again AFAIK, Java code isn't.
What's the problem with using 5.3 and SSL? 5.2 goes out of service in a month!

Do a "man encrypt" on your solaris box.
The decrypt function may or may not work - depending if you're based in the US or not I think.
I don't know whether it is available on OS/390 Z/OS or not - it's a standard Unix C function, so maybe.
Without decryption you're really stuck. Why can't you upgrade to 5.3? |

Thanks for the information.
We do have plans for upgrading to 5.3, but that is not yet decided.
Our ZO/S server is in Germany, so decrypt function may not be available , am I right? In this case can I use channel exits using C language?
If u have any, please mail to nveswar_01@yahoo.co.in
Many Thanks in Advance

If u have any C programs, please mail to nveswar_01@yahoo.co.in
Can I apply these exits to only one message of all messages which goes thru same channel?
Many Thanks in Advance

Channel exits MUST (AFAIK) be in "C". There are sample channel exits available in /opt/mqm/samp.
AFAIK, if you have a MSGEXIT defined, it runs for every message. |

Hi dgolding,
Thanks for the reply.
In my case I have to encrypt/decrypt for only one message. If u have any idea please share with me, at the same time I can't create one more channel for this purpose.
By the way, what do u mean by "AFAIK". I dont understand this.
Many Thanks

but if you use the search facility on this web-site and look for SSL you should get plenty of info.
