Problems with d2i_PKCS8PrivateKey_bio function

[Carlos Roberto Zainos H]

Hi Dr Henson and openssl users list.

 

I'm very thankful by your answers.

 

This time I'm having problems with the d2i_PKCS8PrivateKey_bio function. This always returns me 0 , and really I don't know what's wrong.

My code:

RSA *rsa;
EVP_PKEY *dec_key, **x=NULL;

BIO *in=NULL;

char *password = "am01key";
char *priv_key_der = "llaveAMp5.key";/*PBE privkey file */

int i,size_llave=0;

 

OpenSSL_add_all_algorithms();
ERR_load_crypto_strings();

 

in=BIO_new(BIO_s_file());
if (in==NULL) /*not problem */
 {
  /* Error code*/

 }
  
 if (BIO_read_filename(in,priv_key_der) <= 0) /*not problem*/
 {
    /*Error Code*/

 }

 /*dec_key=EVP_PKEY_new(); comment this because I thought could be the problem*/
dec_key=d2i_PKCS8PrivateKey_bio(in, x, NULL,password);
if (dec_key=NULL) /*also not problem*/
 {
  /*Error code */

 }

size_llave=EVP_PKEY_size(dec_key); /*result of this function is always 0 */

printf("%d\n", size_llave); /*prints zero 0 */

 

rsa=RSA_new();
rsa=EVP_PKEY_get1_RSA(dec_key); /*this function breaks because dec_key is 0 size bytes, right ? */

 

With all my test keys the results are the same (privkeyp5.key, privkeyp8.key, privkey_der.key). Is there some type of bug ? Or this is caused by my C code??

 

I'm a little desperate.....

Thanks again in advance

Zainos
