Using:
FIPS Object Module 2.0.9
OpenSSL 1.0.1l
When I call RSA_generate_key:
if (rsa = RSA_generate_key(keySize, RSA_F4, NULL, NULL))
I get the following error string:
(OPENSSL error:04081078:rsa routines:RSA_BUILTIN_KEYGEN:key size too small)
As I understand, RSA Key size must be 2048
I would like to call this function to generate the same public/private
key everytime.
I thought all I had to do was create the same seed using RAND_seed each
time, however I still keep getting different key pairs.
Is there any way to have RSA_generate_key generate the same
public/private key
RSA_generate_key generate the same
public/private key each time? (I know this doesn’t make sense security
wise, but the work I have to do requires it).
Replace RSA_generate_key with your own function that returns the desired
key. Using the same seed each time won't work because intervening
operations can
Hi David,
1. I am not sure what you mean by replacing RSA_generate_key with my own
function, because I would like it to go through the process of creating
prime numbers, and modulus, etc. Basically I want the RSA_generate_key
to generate the same public key at startup each time my process runs
Hi ,
Someone could y tell me how can I extract public and private keys from RSA
structure returned by the function RSA_generate_key?
I'm using openssl in my c simulation work and I must exchange public keys
between simulated server and client, the encrypt and decrypt the message..
I cannot

// RSA_size() will determine how much memory must be allocated for an
if(rsa1==NULL) {
printf(NO RSA!\n\n

The PRNG is seeded automatically using platform specific entropy. If it wasn't
they key would not be generated and you'd get a PRNG not seeded error.

Hi,
I'm trying to create an RSA keypair with the RSA_generate_key function.
After seeding the PRNG with some random values, I call RSA_generate_key this way:
RSA *pRsa = RSA_generate_key(
1024, // key length
257, // exponent
progress, // shows progress
NULL
Please ignore that message: I accidently linked against the OpenSSL library
while using libeay32.dll from the MKS toolkit :-/
