[openssl-users] OpenSSL 1.1.0 providing new OIDs to source code

[Richard Levitte]

This all sounds a bit mysterious...

would you mind sharing a test program that shows the problem, with
detailed step by step instructions (among others what libraries you're
running against each time)?  Preferably as a github issue, but here is
fine as well...

Cheers,
Richard

Matthias.Ballreich> Did not make any difference…
Matthias.Ballreich> 
Matthias.Ballreich> The Integer value of MY_NID will be printed out and is the correct

Matthias.Ballreich> And i tried another thing. I replaced the two dll-libraries with the

Matthias.Ballreich> then i build this, which has added a new x509 extension (Admission),
Matthias.Ballreich> which has a new OID (NID_extX509Admission, etc.) and there the short
Matthias.Ballreich> and long name will be printed out correctly after Building the Code.
Matthias.Ballreich> So this is a Little bit strange.
Matthias.Ballreich> 
Matthias.Ballreich> Or must i replace the dll-libraries every time i build the Code? But
Matthias.Ballreich> when, why has it worked with the old ones and the 1.1.1-dev (master

Matthias.Ballreich> matthias.ballreich> Hi there,
Matthias.Ballreich> matthias.ballreich>
Matthias.Ballreich> matthias.ballreich> i want to contribute some more OIDs. Therefore i
Matthias.Ballreich> added the OIDs inside
Matthias.Ballreich> matthias.ballreich> the „Objects.txt“ inside /crypto/objects
Matthias.Ballreich> matthias.ballreich>
Matthias.Ballreich> matthias.ballreich> Then i run these commands:
Matthias.Ballreich> matthias.ballreich>
Matthias.Ballreich> matthias.ballreich> perl objects.pl objects.txt obj_mac.num .
Matthias.Ballreich> matthias.ballreich> ./../include/openssl/obj_mac.h
Matthias.Ballreich> matthias.ballreich>
Matthias.Ballreich> matthias.ballreich> perl obj_dat.pl ../../include/openssl/obj_mac.h
Matthias.Ballreich> obj_dat.h
Matthias.Ballreich> matthias.ballreich>
Matthias.Ballreich> matthias.ballreich> perl objxref.pl obj_mac.num obj_xref.txt >
Matthias.Ballreich> obj_xref.h
Matthias.Ballreich> 
Matthias.Ballreich> Sure, that looks fine to me
Matthias.Ballreich> 
Matthias.Ballreich> matthias.ballreich> The files are generated / updated. Then i build
Matthias.Ballreich> the source which
Matthias.Ballreich> matthias.ballreich> builds fine without any exceptions. Then i tried
Matthias.Ballreich> to use the generated
Matthias.Ballreich> matthias.ballreich> NIDs in my Code. For test purposes i tried to
Matthias.Ballreich> print out the short and
Matthias.Ballreich> matthias.ballreich> Long Name of my new oid with OBJ_nid2sn(MY_NID)
Matthias.Ballreich> and OBJ_nid2(MY_NID).
Matthias.Ballreich> matthias.ballreich> But here it prints out an empty string.
Matthias.Ballreich> matthias.ballreich>
Matthias.Ballreich> matthias.ballreich> When o try to use my NID with X509_get_ext_by_NID
Matthias.Ballreich> (cert, MY_NID, -1)
Matthias.Ballreich> matthias.ballreich> the Output is -2.
Matthias.Ballreich> matthias.ballreich>
Matthias.Ballreich> matthias.ballreich> So where is the Problem or what i’m doing wrong
Matthias.Ballreich> here? Thanks!
Matthias.Ballreich> 
Matthias.Ballreich> If you've come that far, MY_NID (which I assume is really
Matthias.Ballreich> NID_whatever) obviously exists, or your code wouldn't even have
Matthias.Ballreich> compiled. One possibility remains, that for some reason, libcrypto
Matthias.Ballreich> hasn't been initialised like it should. This can happen if you only
Matthias.Ballreich> call a very select set of OpenSSL functions. What happens if you add
Matthias.Ballreich> this at the start of your main()?
Matthias.Ballreich> 
Matthias.Ballreich> OPENSSL_init_crypto(0, NULL);
Matthias.Ballreich> 
Matthias.Ballreich> (note, that should be seen as a temporary measure, as this is called
Matthias.Ballreich> internally in quite a number of spots, so for larger uses of OpenSSL
Matthias.Ballreich> functionality, you shouldn't need that)
