PassTLSClientCert adds the selected data from the passed client TLS certificate to a header.

## Configuration Options
|
|
|
|
### General
|
|
|
|
PassTLSClientCert can add two headers to the request:
|
|
|
|
- `X-Forwarded-Tls-Client-Cert` that contains the pem.
|
|
- `X-Forwarded-Tls-Client-Cert-Info` that contains all the selected certificate information in an escaped string.
|
|
|
|
!!! info
|
|
|
|
* `X-Forwarded-Tls-Client-Cert-Info` 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.

### `pem`
|
|
|
|
The `pem` option sets the `X-Forwarded-Tls-Client-Cert` header with the certificate.

|
|
!!! 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:
|
|
|
|
