Dear all, I want to know the way to implement to
set the CRLNumber extension in CRL using openssl-0.9.7 beta 3.
In the crypto/x509v3 directory, there is a flie v3_ini.c. In this
source code, the X509V3_EXT_MEHTOD is already defined. Fisrt I think
that I should add the(X509V3_EXT_S2I)s2i_ASN1_INTEGER in the structure,
since the s2i_ASN1_INTEGER code is also defined in v3_util.c.
59 #include <stdio.h>
60 #include "cryptlib.h"
61 #include <openssl/x509v3.h>
62
63 X509V3_EXT_METHOD v3_crl_num = {
64 NID_crl_number, 0, ASN1_ITEM_ref(ASN1_INTEGER),
65 0,0,0,0,
66 (X509V3_EXT_I2S)i2s_ASN1_INTEGER,
67 0,
68 0,0,0,0, NULL};
69
In line 67, I will add the (X509V3_EXT_S2I)s2i_ASN1_INTEGER
In the CRLNumber extension, the ASN.1 in RFC 3280 says:
CRLNumber ::= INTEGER (0..MAX)
Then I should define the ASN1 macro, but now I do no know how to
define the ASN1 macro to define the ASN.1.
Looking at some others examples, if you have a sequence tag, the macro
will start like :
ASN1_SEQUENCE(....)
...
ASN1_SEQUENCE_END(....)
However the CRLNumber is just INTEGER. I want to know simply just
define the macro to use or any pointer to take a look at.
I would be very appreciated if you give me some suggestion.
Sincerely,
-Kiyoshi
