provideIdentity(for:completionHandler:)

Provide the identity and an optional certificate chain to be used for authentication.

Declaration

optional func provideIdentity(for connection: NWTCPConnection, completionHandler completion: @escaping (SecIdentity, [Any]) -> Void)

connection:
The connection sending this message
completion:
The completion handler for passing an identity and certificate chain to the connection. The identity is required and must not be nil. The certificateChain argument is optional, and is an array of one or more Seccertificate objects. The certificate chain must contain objects of type SecCertificateRef only. If the certificate chain is set, it will be used. Otherwise, the leaf certificate will be extracted from the Secidentity object and will be used for authentication.
The caller is responsible for keeping the argument object(s) valid for the duration of the completion handler invocation.

Optional. If this method is not implemented, the default certificate evaluation will be used.
