a GTlsCertificate chain
the purpose that this certificate chain will be used for.
the expected peer identity. [allow-none]
used to interact with the user if necessary. [allow-none]
additional verify flags
a GCancellable, or NULL. [allow-none]
the appropriate GTlsCertificateFlags which represents the result of verification.
GException on failure.
Verify's a certificate chain after looking up and adding any missing certificates to the chain. chain is a chain of GTlsCertificate objects each pointing to the next certificate in the chain by its issuer property. The chain may initially consist of one or more certificates. After the verification process is complete, chain may be modified by adding missing certificates, or removing extra certificates. If a certificate anchor was found, then it is added to the chain. purpose describes the purpose (or usage) for which the certificate is being used. Typically purpose will be set to G_TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER which means that the certificate is being used to authenticate a server (and we are acting as the client). The identity is used to check for pinned certificates (trust exceptions) in the database. These will override the normal verification process on a host by host basis. Currently there are no flags, and G_TLS_DATABASE_VERIFY_NONE should be used. This function can block, use g_tls_database_verify_chain_async() to perform the verification operation asynchronously.
