C++ (Cpp) sodium_munlock Examples

Example #1

int main(int argc, char **argv)
{
	if( rdrand_available() ) {
		fprintf( stderr, "rdrand supported.\n" );
	} else {
		fprintf( stderr, "rdrand NOT supported.\n" );
	}

	sodium_mlock( buf, 64 );
	char hex[130];
	char *result;

	while( 1 ) {

		result = sodium_bin2hex( hex, 129, (unsigned char*)buf, 64 );
		if( result ) {
			printf( "%d: %s\n", received_entropy, result );
		}
