HP-UX Trusted Computing Services A.01.00 Administrator's Guide

B Sample TSS Application
This sample program creates and registers a new key in TSS. The new key is then used to encrypt
a secret. The results are displayed in the output.
Makefile.hpux and example.c 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

#include <string.h>
