Hi,
We are using openSSL in OpenAT-FXT modem. the version used is 0.9.8h. When I
am calling function to generate keys, it goes into infinite loop inside the
function and system got crashed.
By entering traces, I checked the flow of code
Code is given below ----
const int kBits = 4096;
RSA *rsa = RSA_new();
BIGNUM *f4 = BN_new();
BN_GENCB *cb = NULL;
BN_set_word(f4, RSA_F4);
static const char rnd_seed[] = "string to make the random number generator
think it has entropy";
RAND_seed(rnd_seed, sizeof(rnd_seed));
ret = RSA_generate_key_ex(rsa, kBits, f4, cb);
rsa_builtin_keygen(rsa, bits, e_value, cb);
BN_generate_prime_ex(rsa->p, bitsp, 0, NULL, NULL, cb)
i=BN_is_prime_fasttest_ex(ret,checks,ctx,0,cb); //this function
returns 0, so it goes back on loop: to make a random number
j = witness(check, A, A1, A1_odd, k, ctx, mont); //witness is
returning 1
Any help to solve the problem be appreciated
