Thanks Robert, I haven't seen a cite to bdes in the FM of des(3), but
the problem is solved using the source of bdes(1) [thanks to Antone].
The code would be as easy as:
#include <openssl/des.h>
int
main(int argc, char *argv[])
{
DES_key_schedule schedule;
DES_cblock key;
strncpy(key, "somekey", 8);
DES_set_key(&key, &schedule);
DES_cblock buf;
strncpy(buf, "sometxt", 8);
// Encrypting
DES_ecb_encrypt(&buf, &buf, &schedule, 0);
// Decrypting
DES_ecb_encrypt(&buf, &buf, &schedule, 1);
printf("Text Is: %s\n", buf);
return(0);
}
