On my dev box, I get this error in the decrypt function when the environment connection string does not match my environment key. We register a key for each environment (dev, QA, etc.) which is used for the decrypt. Obviously, if the registered key is
for a different environment than the connection string, the decrypt doesn't work.
It would be nice if the error message made more sense for this situation, but this is the error that we get when we have this key-connectionstring mismatch.
i just got this error poping up on two sites today. Both are .net 2.0 use ajax components. I recently added both to several major free search engines. Perhaps its a crawler doing something?
are you all still experiencing these errors? did they last only for a while?
I'm getting this same error in Firefox if I request my default page, which reads an encrypted cookie, if the session has expired. Any ideas on how to fix this?
