Methods

__construct()

The constructor.

Exceptions

Throws SetaPDF_Signer_Exception

_cleanUp()

getCertificate()

Get the certificate parameter.

getExtraCertificates()

Get the extra certificate parameter.

getPrivateKey()

Get the private key parameter

setCertificate()

public void SetaPDF_Signer_Signature_Module_OpenSsl::setCertificate ( mixed $certificate )

Set the certificate parameter.

This module make use of the build in openssl functions. So the certificate parameter has to be passed as defined here: http://php.net/openssl.certparams.

Some examples:

$module->setCertificate(file_get_contents('path/to/certificate.pem'));
// or
$module->setCertificate('file://path/to/certificate.pem');

Notice the "file://" prefix if you need to pass the certificate path instead of its content.
Parameters
$certificate : mixed
 

setExtraCertificates()

public void SetaPDF_Signer_Signature_Module_OpenSsl::setExtraCertificates ( string $extraCertificates )

Set the extra certificate parameter.

This parameter specifies the name of a file containing a bunch of extra certificates to include in the signature which can for example be used to help the recipient to verify the certificate that you used.

If the certificates are saved in separate files, you will need to assemble them in one single file. Just copy them with a text editor one after another.

Parameters
$extraCertificates : string
 

setPrivateKey()

public void SetaPDF_Signer_Signature_Module_OpenSsl::setPrivateKey ( mixed $privateKey )
