TIP: FIPS 140-2 references a United States standard for the use of cryptography in information processing systems. TIP: The default TLS engine does not support FIPS 140-2 mode, and will always return false. Alternative implementations with such support may be available from commercial suppliers. NOTE: Generally the FIPS 140-2 mode cannot be changed after program startup. == RETURN VALUES True if the TLS engine is in FIPS 140-2 mode, false otherwise. == ERRORS None. == SEE ALSO [.text-left] xref:nng_tls_engine.5.adoc[nng_tls_engine(5)], xref:nng.7.adoc[nng(7)]
