Sometimes, the result of a crypto operation returns a list of invalid keys encountered in processing the request. The following structure is used to hold information about such a key.
This is a pointer to a structure used to store a part of the result of a crypto operation which takes user IDs as one input parameter. The structure contains the following members:
- This is a pointer to the next invalid key structure in the linked list, or
NULLif this is the last element.
- The fingerprint or key ID of the invalid key encountered.
- An error code describing the reason why the key was found invalid.
