I am looking for some routines to perform DES encryption in electronic code
book mode.
I have found the ecb_cyrpt function, however when I try and use it the
buffer is not encrypted.
Am I missing something, do these functions not work, and is there a better
way of doing this?
Below I have included a basic test program I am using to try and get the
encryption working.
Thanks for any help,
- Chris

int main()
{
char testbuf[16] = {0x00,0x01,0x02,0x03,0x04,
0x05,0x06,0x07,0x08,0x09,
0x0a,0x0b,0x0c,0x0d,0x0e,
0x0f} ;
char testkey[8] = {0x01,0x02,0x03,0x04,
0x05,0x06,0x07,0x08} ;
int status ;
int i ;
des_setparity(testkey) ;
status = ecb_crypt(testkey, testbuf, 16, DES_HW | DES_ENCRYPT) ;
printf("status=%d\n", status) ;
for(i=0; i<16; i++)
{
printf("%02x ", (unsigned char)testbuf[i]) ;
}
exit(0) ;
}
