encryption of hex file

Question for the masses. Back in 2011 CCS announced that they added the capability of encrypting a hex file which CCSLoad and, for example, an ICD-U64 would seamlessly load, decrypt, and program the PIC. See here: https://www.ccsinfo.com/newsdesk_info.php?newsPath=ALL&newsdesk_id=134

I can't seem to find any documentation for this feature anywhere. Has anyone used it, and can you point me to any instructions for doing so?

I was interested, so I read the info at the 'link'... If I read 'between the lines', the programmer still 'burns the PIC' with real ML code, not encrypted ?
If so , I can easily get the program....

You can get the program, I can get the program, the people who this is meant for absolutely will not get the program.

It's just meant as a roadblock that they won't be able to overcome without paying someone to do it for them, and there's very little chance of that.

If you run CCSLoad and then expand the Options section by clicking on
the little box with '<<' in it, then it shows a little safe with a combo lock
and it says "Encrypt Hex File". That's all I can find.

Thanks PCM. Will test this weekend and report back here for posterity once I know more.

Sorry it took so long to reply. As PCM pointed out, CCSLoad's Options tab on the main screen, hit the "<<" button, look for the safe icon "Encrypt Hex File". CCSLoad then uses that to program your PIC. Very simple.
