Configuration Options

General

PassTLSClientCert can add two headers to the request:

X-Forwarded-Tls-Client-Cert that contains the escaped pem.
X-Forwarded-Tls-Client-Cert-Info that contains all the selected certificate information in an escaped string.

!!! info

* Each header value is a string that has been escaped in order to be a valid URL query.
* These options only work accordingly to the [MutualTLS configuration](../../https/tls.md#client-authentication-mtls).
That is to say, only the certificates that match the `clientAuth.clientAuthType` policy are passed.

The following example shows a complete certificate and explains each of the middleware options.

!!! info "Extracted data"

The delimiters and `\n` will be removed.
If there are more than one certificate, they are separated by a "`,`".

!!! warning "X-Forwarded-Tls-Client-Cert value could exceed the web server header size limit"

The header size limit of web servers is commonly between 4kb and 8kb.
If that turns out to be a problem, and if reconfiguring the server to allow larger headers is not an option,
one can alleviate the problem by selecting only the interesting parts of the cert,
through the use of the `info` options described below. (And by setting `pem` to false).

`info`

The info option selects the specific client certificate details you want to add to the X-Forwarded-Tls-Client-Cert-Info header.

The value of the header is an escaped concatenation of all the selected certificate details. But in the following, unless specified otherwise, all the header values examples are shown unescaped, for readability.

The following example shows such a concatenation, when all the available fields are selected:

Subject="DC=org,DC=cheese,C=FR,C=US,ST=Cheese org state,ST=Cheese com state,L=TOULOUSE,L=LYON,O=Cheese,O=Cheese 2,CN=*.example.com";Issuer="DC=org,DC=cheese,C=FR,C=US,ST=Signing State,ST=Signing State 2,L=TOULOUSE,L=LYON,O=Cheese,O=Cheese 2,CN=Simple Signing CA 2";NB="1544094616";NA="1607166616";SAN="*.example.org,*.example.net,*.example.com,test@example.org,test@example.net,10.0.1.0,10.0.1.2"

!!! info "Multiple certificates"

If there are more than one certificate, they are separated by a `,`.

   6a:2f:20:f8:ce:8d:48:52:ba:d9:bb:be:60:ec:bf:79

And it is formatted as follows in the header (decimal representation):

SerialNumber="141142874255168551917600297745052909433"

`info.notAfter`

Set the info.notAfter option to true to add the Not After information from the Validity part.

And it is formatted as follows in the header:

SAN="*.example.org,*.example.net,*.example.com,test@example.org,test@example.net,10.0.1.0,10.0.1.2"

!!! info "Multiple values"

The SANs are separated by a `,`.
