^^^^
you shouldn't give a seedLen of 20 when you don't provide a
buffer with random data.
This is the way I do it:
DSA * pDSA;
unsigned char seed_buf[seed_len];
for (i = 0; i < seed_len; i++) seed_buf[i] = rand(); // well, not
very clever, but works...
pDSA = DSA_generate_parameters(
key_len,
seed_buf,
seed_len,
NULL,
NULL,
callback,
NULL);
DSA_generate_key(pDSA);
with the callback function:
void callback()
{
DoSomethingOrNot();
}
