 Signs and updates the instance certificate using the \module{openssl.pkey} $key$. $type$ is an optional string describing the digest type. See \module{pkey:sign}, regarding which types of digests are valid. If $type$ is omitted than a default type is used---``sha1'' for RSA keys, ``dss1'' for DSA keys, and ``ecdsa-with-SHA1'' for EC keys.
