Suggestions? I could try hammering PayPal's service with an automated script that generates an encrypted and signed block and then submits it until I get one that is deemed bogus, but I don't think they would appreciate that.



Well an indication of the error codes would help. Something just "not
working" doesn't help much...

I don't have access to PayPal's internal systems and neither did the people I spoke with in Technical Support. Apparently only the developers are allowed to know what error messages are generated - and the developers don't get out much. The encrypted and signed data block on my end are generated perfectly every time without any errors from any function (each function is checked for error conditions).

The only error condition given is error 5302. This is an internal PayPal error code and the only known "fix" that Tech. Support has is to remove all whitespace from the PKCS#7 data block. That didn't fix my problem, which only served to confuse the support person. It seemed like a hack'ish sort of fix to me anyway.

Also, it can't be cookie related as Google searches might indicate because I can still feed it the "bad" data block that I have saved locally and get the error and then feed it a "good" data block and have it work fine. I also seriously doubt conventional memory has been exhausted as other Google results might say.

I'm willing to send the data blocks I've got and the relevant section of source code that generated them. The source code is fairly complex, but might shed some light on something that should or should not be done.
