SYNOPSIS

#include <nng/supplemental/tls/tls.h>

bool nng_tls_engine_fips_mode(void);

DESCRIPTION

The nng_tls_engine_fips_mode() returns true if the TLS engine is operating in FIPS 140-2 mode, and false otherwise.

FIPS 140-2 references a United States standard for the use of cryptography in information processing systems.
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.
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.
