== NAME
|
|
|
|
nng_tls_engine_fips_mode - TLS FIPS 140-2 mode indicator
|
|
|
|
== SYNOPSIS
|
|
|
|
[source,c]
|
|
----
|
|
#include <nng/supplemental/tls/tls.h>
|
|
|
|
bool nng_tls_engine_fips_mode(void);
|
|
----
|
|
|
|
== DESCRIPTION
|
|
|
|
The `nng_tls_engine_fips_mode()` returns `true` if the
|
|
xref:nng_tls_engine.5.adoc[TLS engine] is operating in FIPS 140-2 mode,
|
|
and `false` otherwise.
|
|
|
|
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.
