Hi,
currently the p11_child does not continue to search for more
certificates if the first suitable certificate cannot be verified. With
this patch p11_child will continue until a valid certificate is found
(or all are checked).
As said before I'm working on improving the handling of the certificates
for the unit-test and would prefer to not spend time to add a test for
this case with the old scheme. If you agree I would open a ticket to
remind me to add tests for this case with the new scheme.
bye,
Sumit

Subject: [PATCH] p11: check if cert is valid before selecting it
Currently the first certificate was selected and if it was not valid
p11_child just returned an error. With this patch the validity is
checked first and the first valid certificate is selected.

Did you mean to say continue instead of break here?
