I'm having a problem with some code that uses CryptVerifyDetachedMessageSignature to verify a signature blob (the code is essentially the standard code sample for using this function).
The code works on XP, but on Windows 7 will for some users fail verification with an NTE_BAD_LEN error. The documentation on MSDN seems to suggest this error shouldn't be returned by this function. Anyone seen this before, or even have any ideas where to start looking for a cause?
