<pre wrap="">Hi,
I have a problem with porting OpenSSL code from 1.0 to 1.1.
Please do not complain that it does not look like it make sense what
this code does here - complain to Microsoft who implements certs with
RDP non-standard ...
The goal of the following code is to change the ASN.1 value of the
signature algorithm in a certificate.
// OpenSSL 1.0 code, well, really written already when 0.9 was there
nid = OBJ_obj2nid(cert->cert_info->key->algor->algorithm);
if ((nid == NID_md5WithRSAEncryption) || (nid ==
NID_shaWithRSAEncryption)) {
ASN1_OBJECT_free(cert->cert_info->key->algor->algorithm);
cert->cert_info->key->algor->algorithm = OBJ_nid2obj(NID_rsaEncryption);
}
// OpenSSL 1.1 code
nid = X509_get_signature_nid(cert);
if ((nid == NID_md5WithRSAEncryption) || (nid ==
NID_shaWithRSAEncryption)) {
... how to set the algorithm in the cert to NID_rsaEncryption in
OpenSSL v1.1.x?
Any help how to implement this with the new 1.1 functions is highly
appreciated :)

<tt>Strangely, when I look at certificates generated by the "openssl
ca" <br>
utility, they already say "Public Key Algorithm: rsaEncryption", <br>
where did you get certificates that specified
"md5WithRSAEncryption" <br>
or "shaWithRsaEncryption" as the subject public key algorithm?</tt><tt><br>
