Oggetto: x509 read from a buf
>hi all,
>in x509.c , load_cert(char * file , int format)
>read certificate from a file .
>i need read a certificate from a buf ( unsigned char * ),
>a function like
>static X509 *load_cert(unsigned char *data , int len , int format )
>len is the length of data.
>so i change the following :

> if ((cert=BIO_new(BIO_s_file())) == NULL)
> {
> ERR_print_errors(bio_err);
> goto end;
> }
>
> if (file == NULL)
> BIO_set_fp(cert,stdin,BIO_NOCLOSE);
> else
> {
> if (BIO_read_filename(cert,file) <= 0)
> {
> perror(file);
> goto end;
