How do you decode the CInfo data in a Comcast CallerID message?
Comcast has a Adobe Air desktop program that will notify you of caller ID information when a call comes in. It appears to use a standard XMPP protocol, but the payload is encoded in some format.
There are more detail here:

This is what a example message looks like:

nyXpEIgjAs1QbBV2CK1HJjIb+yvTDOMXh5uDGh+Q552jyV6vxPM10+tlhNBfTEvNjB7QJnTHkd2Mmj5
Cl3JCdoRRw8/RTGSzDGrSQwLAmpht6GmS7DNMGcHc=
It does not appear to be BASE64 encoded.

You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

It appears to be BASE64 encoded, but the "decoded" version is then still encoded in some other encoding. It's definately not plaintext. I assume the idea is to block you and I from getting access to this info.
I'm determined to find out :)
