Hello Mailinglist,
in the OpenSSL documentation is written that I should initialize with
RAND_seed() before using RSA_public_encrypt() and RSA_generate_key_ex(). But I
havent found any good examples that show how to do this. (For Windows)
I found this example in the test folder over and over again. But it seems that
this is only a dummy.
static const char rnd_seed[] = "string to make the random number generator
think it has entropy";
RAND_seed(rnd_seed, sizeof rnd_seed); /* or OAEP may fail */
What do you think if I use rand() from cstdlib.h to create a char* string and
put it into RAND_seed():
const int SeedLen=100;
char RandSeed[SeedLen];
srand((unsigned)time(NULL));
for (int i=0; i<SeedLen; i++)
RandSeed[i] = rand() % 256;
Or is there a better way to set rand_seed? I cannot bother a user with key
input or else.
In some test applications I havent seen any rand_seed calls. So maybe it is not
so important?
Regards
Martin
