Hi All,
I have to read x509 certificate(in .pem format) from memory.
I have written two functions.
Fn.1
/* get X509 structure from memory. */
extern X509 *mem2x509(vchar_t *cert)
{
X509 *x509;
unsigned char *bp;
bp = (unsigned char *) cert->v;
x509 = d2i_X509(NULL, &bp, cert->l);
if(x509 == NULL)
{
Printf("ERROR : %s : %d : %s\n ", __FILE__, __LINE__, "failed in
d2ix509()");
}
return x509;
}
Fn.2
extern X509 *mem2x509_bio(vchar_t *cert)
{
X509 *x509= NULL;
BIO *bio = NULL;
int len = -1;
bio = BIO_new(BIO_s_mem());
if (bio == NULL)
{
Printf("ERROR : %s : %d : %s\n ", __FILE__, __LINE__, "failed in
BIO_new()");
return NULL;
}
len = BIO_write(bio, cert->v, cert->l);
if (len == -1)
{
Printf("ERROR : %s : %d : %s\n ", __FILE__, __LINE__, "failed in
BIO_write()");
return NULL;
}
x509 = PEM_read_bio_X509(bio, NULL, NULL, NULL);
if(x509 == NULL)
{
Printf("ERROR : %s : %d : %s\n ", __FILE__, __LINE__, "failed in
PEM_read_bio_X509()");
}
BIO_free(bio);
return x509;
}
Now certificate data is stored in char array.
vchar_t *cacert = NULL;
cacert = vmalloc(strlen(CERT.CACert));
memcpy(cacert->v, CERT.CACert, strlen(CERT.CACert));
Now i m extracting with above two functions.
Fn1 is failling .I m getting "failed in d2i_x509" message.
F2. is passed.
Can some explain the reason ?
if you have a pem encoded certificate d2i_X509 of course fails as
it expects a der encoded binary input.
