-// CertVerifier represents a service for verifying certificates. |
-// |
-// CertVerifier can handle multiple requests at a time, so when canceling a |
-// request the RequestHandle that was returned by Verify() needs to be |
-// given. A simpler alternative for consumers that only have 1 outstanding |
-// request at a time is to create a SingleRequestCertVerifier wrapper around |
-// CertVerifier (which will automatically cancel the single request when it |
-// goes out of scope). |

- // successful or an error code upon failure. |
- // |
- // The |*verify_result| structure, including the |verify_result->cert_status| |
- // bitmask, is always filled out regardless of the return value. If the |
- // certificate has multiple errors, the corresponding status flags are set in |
- // |verify_result->cert_status|, and the error code for the most serious |
- // error is returned. |
- // |
- // |flags| is bitwise OR'd of X509Certificate::VerifyFlags. |
- // If VERIFY_REV_CHECKING_ENABLED is set in |flags|, certificate revocation |
- // checking is performed. |
