i make similar func with test2 of Verify RSA signature in c++ using openssl that executes RSA verification. But i have C2027 compile error.

C2027 found at rsa->n = n; and rsa->e = e;. C2027 generally happen when include file is not enough.

my include file is

#include <openssl/sha.h>
#include <openssl/aes.h>
#include <openssl/cmac.h>
#include <openssl/rsa.h>
#include <openssl/evp.h>

and AES Encrypt/Decrypt, CMAC Generation/Verification, SHA256 is working fine.

n is public key, e is exponent, Msg is message, and S is Signature in following func.

    int ret = 0;

I am using VS2019, Win32Openssl from https://slproweb.com/products/Win32OpenSSL.html and configure VS project according to How to use OpenSSL with Visual Studio.

Does anybody know which include file should be added? Otherwise, how could i modify c source?

The Build error is

  • It would be helpful to include the text of the error message. – TonyK Jun 23 '20 at 17:26
  • Thanks @TonyK, I added Build Error Message. – Soramame Jun 23 '20 at 17:55
  • Well then, you just have to find out where `rsa_st` is defined. – TonyK Jun 23 '20 at 18:11
  • I know nothing about openssl, but I found [this interesting page](https://github.com/openssl/openssl/issues/1491) which bears on your problem. It seems you shouldn't be calling `RSA_new` at all. – TonyK Jun 23 '20 at 18:15
  • Thanks @TonyK, next i will try RSA_set0_key(), but this does not seems good solution for my current problem. So, i will move to EVP function. Thanks again. – Soramame Jun 24 '20 at 11:45

Thanks for @TonyK, i think i could correctly modify my code,

rsa->n = n; and rsa->e = e; is modified to

BIGNUM* nn = BN_bin2bn(n, sizeof(n), NULL);
BIGNUM* ee = BN_bin2bn(e, sizeof(e), NULL);
int ret = RSA_set0_key(rsa, nn, ee, NULL);

But there are more problem for my code so i will make more effort.
