<div class=note>'''Note:''' Cryptographic algorithms whose outputs vary for a given set of inputs (DSA and ECDSA) are tested using a known-answer test. The message digest algorithms have independent known-answer tests.</div> | |||

See the known-answer test for RNG above. | |||
==Software/firmware test== | ==Software/firmware integrity test== | ||
An integrity check is performed on the libraries that contain the NSS cryptographic module. If the check fails, the module immediately enters the Error state. | |||
