README
A simple class that allows to extract the original file from a signed p7m file.
Requirements
- PHP 7.0+
- Symphony Prcess 3.3 or 4.0+
Requirements
Behind the scenes this package leverages openssl. You can verify if the binary installed on your system by issueing this command:
which openssl
If it is installed it will return the path to the binary.
Installation
You can install the package via composer:
composer require filippo-toso/p7m-extractor
Usage
Extracting text from a pdf is easy.
use FilippoToso\P7MExtractor\P7M; $success = (new P7M()) ->setSource('source.pdf.p7m') ->setDestination('destination.pdf') ->save();
Or easier:
use FilippoToso\P7MExtractor\P7M; $success = P7M::convert('source.pdf.p7m', 'destination.pdf');
By default the package will assume that the openssl
command is located at /usr/bin/openssl
.
If it is located elsewhere pass its binary path to constructor
use FilippoToso\P7MExtractor\P7M; $success = (new P7M('/custom/path/to/openssl')) ->setSource('source.pdf.p7m') ->setDestination('destination.pdf') ->save();
or as the last parameter to the extract()
static method:
$success = P7M::convert('source.pdf.p7m', 'destination.pdf', '/custom/path/to/openssl');
If you want to get the content as a string instead of saving it to a file you can use the get()
method or the extract()
static method.
If you need to change the command or add additional parameters to openssl, you can use the setParams()
methods
use FilippoToso\P7MExtractor\P7M; $success = (new P7M('/custom/path/to/openssl')) ->setParams(['{$openssl}', 'cms', '-verify', '-noverify', '-no_attr_verify', '-binary', '-in', '{$source}', '-inform', 'DER', '-out', '{$destination}']) ->setSource('source.pdf.p7m') ->setDestination('destination.pdf') ->save();
The {$openssl}, {$source}, {$destination} tokens are replace dinamically with the openssl executable, source and destination paths.
