typedef void (*SilcSKEVerifyCbCompletion)(SilcSKE ske,

    Completion callback that will be called when the public key
    has been verified.  The `status' will indicate whether the public
    key were trusted or not. If the `status' is PENDING then the status
    is not considered to be available at this moment. In this case the
    SKE libary will assume that the caller will call this callback again
    when the status is available. See silc_ske_set_callbacks for more
    information.
