--cert-selector multiple RDNs example

[anton-stamenov-SWO]

I can't figure out how to create the sector.json in order to pass multiple RDNs for x509Subject and x509Issuer keys.

If I set just the x509Serial, the certificate is found, but adding the subject or issuer with multiple RDNs is not working.

[
    {
        "Key": "x509Subject",
        "Value": "DC=global, DC=domain, OU=Productive, OU=Users, OU=End Users, OU=EMEA, OU=BG, CN=Stv An, emailAddress=an.stv@mkkvt.com"
    },
    {
        "Key": "x509Issuer",
        "Value": "C=CH, ST=ZH, L=Wallisel, O=MKKVT GmbH, OU=BIT, CN=MKKVT Issuing Certificate Authority 2"
    },
    {
        "Key": "x509Serial",
        "Value": "2A000539A0855247927C658F440000000539A0"
    }
]

Unfortunately the current logic is implemented as a complete string match. We're looking to change that in future.

For now, you can try using the read-certificate-data diagnostic command to find how the values should look in order for the application to match them.

I used read-certificate-data, but the output it returned did not clearly indicate how to relate it to the selector configuration.

Here is an example with my certificate:

$ aws_signing_helper read-certificate-data --cert-selector file://$HOME/bin/.aws_signing_helper_selector.json

I've tested copying everything inside the quotes as "x509Subject," and it worked.

Now I realise that some of the OIDs are not resolved, and DER encoding is used for values. These unresolved OIDs look okay in OpenSSL, and values are visualised as strings. I've also dumped the types, and IA5STRING is DER encoded, and PRINTABLESTRING is strings. Anyway, I couldn't make OpenSSL to output the subject DN in a suitable format.

What about x509Issuer format? Is it just x509Subject only visible through read-certificate-data?

$ cat as.pem | openssl x509 -noout -subject -nameopt RFC2253

subject=emailAddress=an.stv@mkkvt.com,CN=Stv An,OU=BG,OU=EMEA,OU=End Users,OU=Users,OU=Productive,DC=domain,DC=global

Sorry for the late response, but the latest release (1.7.0) should also print information about the certificate issuer when you run read-certificate-data.
