gnupg_import Failure
http://www.php.net/manual/en/function.gnupg-import.php
The return array consists of the following values: ( [imported] => (int), [unchanged] => (int), [newuserids] => (int), [newsubkeys] => (int), [secretimported] => (int), [secretunchanged] => (int), [newsignatures] => (int), [skippedkeys] => (int), [fingerprint] => (string) ) When invalid content is passed, all values, even skippedkeys, is 0. The fingerprint value does not exist then.
If the directory .gnupg under the user’s home directory cannot be created or cannot be written to, the import will fail, just like the comment above. It will not specify what the issue is however, it just will not import correctly.
