I have to “manually” encode the OID and innerContextToken.

The data is not correct if it supposed to match RFC 2743.
The first byte is [APPLICATION 0]. That seems fine.
The second byte provides a length for the full SEQUENC

You can tell i2d to encode using "application" tagging like this:
ASN1_item_ex_i2d((const ASN1_VALUE **)&negToken, &p,
ASN1_ITEM_rptr(GSSAPI_CONTEXTTOKEN), 0,
,
is there a way to get decode with openssl anyway?

Right, I had missed that algorithm identifier is a sequence. Now it makes
sence. Thanks!

you can see using the lengths the second sequence contains only
algoritm oid and parameters (in this case NULL parameters). This is
AlgorithmIdentifier.
Below the bit string contains the der encoding of subjectPublicKey
(encoded).

Thanks, that explains the 0x30 tag value. What about the DER encoding? Is that
correct?
The 'openssl asn1parse' output of the DER encoding is:
0:d=0 hl=3 l= 159 cons: SEQUENCE
3:d=1 hl=2 l= 13 cons: SEQUENCE
5:d=2 hl=2 l= 9 pr

subjectPublicKey should hold the DER
encoding of the following ASN.1 defintion:
RSAPublicKey ::= SEQUENCE {

publicExponent INTEGER } -- e
In order to achieve this encoding I tried to call i2d_X509_PUBKEY(). The DER

Hi,
I'm trying to write a pkcs7 object with following code to a file:
unsigned char *tmp, signature;
int iLen;
iLen = i2d_PKCS7(p7, NULL);
signature = (unsigned char*) malloc(iLen);
tmp = signature;
iLen = i2d_PKCS7(p7, &tmp);
FILE *fpkcs7 = fopen("C:\\sig.p7s", "w+");

Very well! thanks.
Where can I find the documentation to learn about to use the mini compiler?

Hi,
how can I obtain a word in the DER-encoding form?
I need it represented in octets to use it in custom extensions definition.
for example: 1e:08:00:55:00:73:00:65:00:72

Hi Gomez,
I'll try to find a working example of a MSIE 4.0 certificate request html

Can you point me some links ???

I'm trying to generate a certificate for IE 4.
The .p12 generated by the following script is successfully imported in
NS.
But the DER encoded cert generated from .pem' one via
$ssleay x509 -in $sslcrtdir/$user.crt -outform DER -out
$sslcrtdir/$user.der
Any Idea...
