Description: Reference for Gio.TlsCertificate.new_from_pkcs11_uris

### Constructor

# Gio TlsCertificatenew_from_pkcs11_uris

since: 2.68

#### Declaration [src]

    GTlsCertificate*
    g_tls_certificate_new_from_pkcs11_uris (
      const gchar* pkcs11_uri,
      const gchar* private_key_pkcs11_uri,
      GError** error
    )

#### Description [src]

Creates a `GTlsCertificate` from a PKCS #11 URI.

An example `pkcs11_uri` would be `pkcs11:model=Model;manufacturer=Manufacture;serial=1;token=My%20Client%20Certificate;id=`01“

Where the token’s layout is:

    Object 0:
      URL: pkcs11:model=Model;manufacturer=Manufacture;serial=1;token=My%20Client%20Certificate;id=%01;object=private%20key;type=private
      Type: Private key (RSA-2048)
      ID: 01

    Object 1:
      URL: pkcs11:model=Model;manufacturer=Manufacture;serial=1;token=My%20Client%20Certificate;id=%01;object=Certificate%20for%20Authentication;type=cert
      Type: X.509 Certificate (RSA-2048)
      ID: 01

In this case the certificate and private key would both be detected and used as expected. `pkcs_uri` may also just reference an X.509 certificate object and then optionally `private_key_pkcs11_uri` allows using a private key exposed under a different URI.

Note that the private key is not accessed until usage and may fail or require a PIN later.

Available since: 2.68

#### Parameters

`pkcs11_uri`

  Type: `const gchar*`

  A PKCS #11 URI.

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`private_key_pkcs11_uri`

  Type: `const gchar*`

  A PKCS #11 URI.

  The argument can be `NULL`.
  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the constructor if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `GTlsCertificate`

The new certificate, or `NULL` on error.

The caller of the function takes ownership of the data, and is responsible for freeing it.
