=Power-Up Self-Tests=


The module can perform the following power-up self-tests:
==Cryptographic algorithm tests==
A known-answer test is conducted for all cryptographic functions (e.g., encryption, decryption, authentication, and random number generation) of each Approved cryptographic algorithm implemented by the cryptographic module. (See the [http://www.mozilla.org/projects/security/pki/nss/fips/nss-source/mozilla/security/nss/lib/softoken/fipstest.c.html power-up self-tests source code].)

<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>
==Random number generator test==
See the known-answer test for RNG above.
==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.
==Critical functions test==
No other critical functions tests are performed on power-up.
