Hello Driss,
I think, it will be
theDESCheckResult = DES_set_key_checked(&theDESKey1, &theSchedule);
DES_ecb_encrypt((DES_cblock *) &buff, (DES_cblock *) &theOutput, &theSchedule, DES_ENCRYPT);
Namely that DES_ecb_encrypt is described like that :
void DES_ecb_encrypt(const_DES_cblock *input, DES_cblock *output,
DES_key_schedule *ks, ...

Hello,
I need to encrypt a password with a DES key, I'm trying the following code:
char * buff[20];
int theDESCheckResult;
DES_cblock * theDESKey1;
DES_key_schedule *theSchedule;
DES_cblock * theOutput;
ALMLog (@"Enter your DBPassword");
fgets((char *)&buff, 10, stdin);
theDESKey1 = [[[NSProcessInfo processInfo] globallyUniqueString] UTF8String];
RAND_seed(theDESKey1, strlen(theDESKey1));
theDESCheckResult = DES_set_key_checked(theDESKey1, theSchedule);
DES_ecb_encrypt(buff, theOutput, theSchedule, DES_ENCRYPT);
The DES key is correctly generated but the DES_set_key_checked () function returns -1 which means that the parity is wrong and the function DES_ecb_encrypt () cannot be executed.
