Runtime error with SSL_CTX_use_PrivateKey_file function

[Anita Kumar]

Hi,
   
  I'm trying to use the encrypted private key for my test SSL server. 
   
  I generated an encrypted private key cert_27.key using genrsa tool and I gave 
a paswd to it. I wrote a call back function as follows, which just stores my 
passwd into buf character buffer.
    static int password_callback(char *buf, int size, int rwflag, void 
*userdata)
  {
    /* For the purposes of this demonstration, the password is "ibmdw" */
  printf("*** Callback function called\n");
  strcpy(buf, "ibmdw");
  return 1;
  }

  Now, I tried to load the private key in my server application as follows
   
    int main()
  {
    SSL_CTX *ctx;
  SSL *ssl, *ssl1;
  BIO *bio, *abio, *out;
  int p;
  char r[1024];
  CRYPTO_malloc_init(); 
  SSL_library_init();
  SSL_load_error_strings();
  ERR_load_BIO_strings();
  ERR_load_SSL_strings();
  OpenSSL_add_all_algorithms();
  printf("Attempting to create SSL context... ");
  ctx = SSL_CTX_new(SSLv23_server_method());
  if(ctx == NULL)
  {
    printf("Failed. Aborting.\n");
  return 0;
  }
  printf("\nLoading certificates...\n");
  SSL_CTX_set_default_passwd_cb(ctx, &password_callback);
  if(!SSL_CTX_use_certificate_file(ctx, "signedcert_27.pem", SSL_FILETYPE_PEM))
  {
    ERR_print_errors_fp(stdout);
  SSL_CTX_free(ctx);
  return 0;
  }
  printf("\nLoading Private key...\n");
  if(!SSL_CTX_use_PrivateKey_file(ctx, "cert_27.key", SSL_FILETYPE_PEM))
  {
    ERR_print_errors_fp(stdout);
  SSL_CTX_free(ctx);
  return 0;
  }
  }
   
  when executing this application, i get the following runtime error in the 
function, SSL_CTX_use_PrivateKey_file
   
  OPENSSL_Uplink(100EB010,07): no OPENSSL_Applink.
   
  When I comment the SSL_CTX_set_default_passwd_cb() line. The executable is 
running, it asks for pem passphrase. When I enter the password, everything is 
fine. But, I did not want this behaviour as I need to enter the passwd from 
screen.
  I would appriciate if I get nay comments on this.
  Thanks and Regards,
  Renuga.
