This interface reflects a container of
verification results. Call will not block.
Obtain an array of human readable strings describing
the certificate’s certified usages.
Mirrors the results produced by
nsIX509Cert::getUsagesArray()
As of today, this function is a one-shot object,
only the first call will succeed.
This allows an optimization in the implementation,
ownership of result data will be transfered to caller.
| cert | The certificate that was verified. |
| verified | The certificate verification result, see constants in nsIX509Cert. |
