Thanks for the reply, let me pick your braina little farther.
Take this for example:
<key>org.mozilla.firefox</key>
<array>
<data>
AAAAAACiAAMAAQAAwXGNSQAASCsAAAAAAAAAFgAH3LUAAMGaoMwA
AAAACSD//gAAAAAAAAAA/////wABAAQAAAAWAA4AGAALAEYAaQBy
AGUAZgBvAHgALgBhAHAAcAAPABoADABNAGEAYwBpAG4AdABvAHMA
aAAgAEgARAASABhBcHBsaWNhdGlvbnMvRmlyZWZveC5hcHAAEwAB
LwD//wAA
</data>
</array>
This is what is put in that file I mentioned in my first email. I've tried doing something like:
Base64.encode64('org.mozilla.firefox') #ruby
Which ends up being: b3JnLm1vemlsbGEuZmlyZWZveA==
So my question then becomes, what else is happening to generate this huge hash?
Anymore ideas?
Thanks much

Specifically:
Data bytes are base-64 encoded between the <data> and </data>
tags.
This is not an endorsement to to edit preferences of system frameworks manually without using the proper supported API (or requesting API if none exists).

I'm looking for what is used to generate the <data> values in plist's. For example. if you check "Open with rosetta" from an Application's "get info". It puts an entry in com.apple.LaunchServices.plist
under LSPrefsFatApplications. What is it putting in the <data> field?
If you use plutil to convert the file to xml, you'll see some sort of hash. Where can I find out how that is generated, or some more resources?
I've been doing some research and know that the <data> represents a CFData object, but what in this case is creating the values in this situation?
Sorry if this isn't the right list, I can't find just the right place to be asking this..
