C Sample TSS Application

This sample program creates and registers a new key in TSS. The new key encrypts an ASCII

string. The results are displayed in the output.

The Makefile.hpux and example.c files are located in the /opt/tcs/src/example/

directory. The make –f Makefile.hpux command compiles both 32-bit and 64-bit versions

of example.c.

Example of Makefile.hpux:

CC=cc

INC=/opt/tcs/include

LIBS=-L/usr/lib -ltspi -lcrypto

CFLAGS=-Ae -I$(INC) -DHPUX -g

all: example example64

example: example.c

$(CC) $(CFLAGS) -o example example.c $(LIBS)

example64: example.c

$(CC) $(CFLAGS) +DD64 -o example64 example.c $(LIBS)

clean:

rm -f *.o *~ core example example64

Example of example.c:

#include <stdio.h>

#include <string.h>

#include <unistd.h>

#include <ctype.h>

#include <trousers/tss.h>
