Certification Authority

Manage the creation of certificates. Allow to create a Certificate Authority and sign the childs certificates.

It allow to manage the CSR (Certificate Signing Request), allow alternate names, create private keys if needed

Example 1 : Create a Certificate Authority and get private and public keys

$certificationauthority = new certificationauthority ();
$certificationauthority->createCA ("FR", "FOURNIER38", "CATEST");
$caCert = $certificationauthority->caCert ();
$caKey = $certificationauthority->caKey ();

Example 2 : Create a new Certificate Signing Request

$certificationauthority = new certificationauthority ();
$csr =  $certificationauthority->createCSR ("FR", "FOURNIER38",
        "COMPUTER.fournier38.fr");
$key = $certificationauthority->privateKey ();

Example 3 : Sign a CSR (cert is valid 1 year)

$certificationauthority = new certificationauthority ();
$certificationauthority->caKey ("The PEM CA key");
$certificationauthority->caCert ("The PEM CA Cert");
$cert = $certificationauthority->signCSR ($csr, $caCert, $caKey);

Example 4 : Sign a CSR (cert is valid 2 year)

$certificationauthority = new certificationauthority ();
$certificationauthority->caKey ("The PEM CA key");
$certificationauthority->caCert ("The PEM CA Cert");
$cert = $certificationauthority->signCSR ($csr, $caCert, $caKey, 365 * 2);

Example 5 : Sign a CSR (cert is valid 2 year, and alternate names)

$certificationauthority = new certificationauthority ();
$certificationauthority->caKey ("The PEM CA key");
$certificationauthority->caCert ("The PEM CA Cert");
$cert = $certificationauthority->signCSR ($csr, $caCert, $caKey, 365 * 2,
  ["ALT1.example.com","ALT2.example.com"]);
