Question

我正在尝试在CSR中添加自定义OID

string subject = "CN=Name,O=Org,C=IN,ST=KA,OU=OrgUn,PostalCode=560103";
X509Name sub = new X509Name(subject);
var oidList = sub.GetOidList();
var valueList = sub.GetValueList();

DerObjectIdentifier Oid1 = new derObjectIdentifier("1.53.4.64");//here 1.53.4.64 is custom OID
oidList.Add(Oid1);
valueList.Add("Some Value");

DerObjectIdentifier Oid2 = new DerObjectIdentifier("1.53.4.65");
oidList.Add(derObjectIdentifier2);
valueList.Add("Some value");

X509Name subjectFinal = new X509Name(oidList, valueList);

Pkcs10CertificationRequestDelaySigned pkcs10 = new Pkcs10CertificationRequestDelaySigned(signatureAlgorihtm, subjectFinal, publicKeyParameters, null);

所有内容编译并正常工作但是当我解码并检查CSR时，自定义Oid名称的值在ASN.1信息中从1.53.4.65更改为其他值2.13.4.64 。

这是添加自定义OID值的正确方法

添加自定义OID属性的代码是正确的，但是我们不能使用任何随机数作为OID，它必须为ex 1.3.6.1.4.1.XXXX.X.X注册，或者它必须具有某种格式。
