The php-crypto is an objective wrapper for OpenSSL Crypto library.
Before starting with installation of this extensions, the OpenSSL library
has to be installed. It is defaultly installed on the most Linux distributions.
The minimal version of OpenSSL that is supported is 1.1.1.
Of course PHP has to be installed too. The minimal version that is supported is 5.6 as the extension uses namespaces.
The RPM package for PHP Crypto is available in Remi's repository: http://rpms.famillecollet.com/
It is available for Fedora, RHEL and clones (CentOS, SC and others).
After downloading remi-release RPM, the package can be installed by executing following command:
$ sudo yum --enablerepo=remi install php-pecl-crypto
This extension is available on PECL. The package is not currently stable.
If the config preferre_state is stable, then the version needs to be specified.
$ sudo pecl install crypto-0.x.y
where x is an installed minor version number and y bug fixing version number.
It's important to have a git installed as it's necessary for recursive fetch of phpc.
First clone recursively the repository
git clone --recursive https://github.com/bukka/php-crypto.git
Then go to the created directory and compile the extension. The PHP development
package has to be installed (command phpize must be available).
cd php-crypto
phpize
./configure
make
sudo make install
Finally the following line needs to be added to php.ini
extension=crypto.so
Be aware that master branch contains a slightly different error handling. You can see examples for more details.
Precompiled binary dll libraries for php-crypto are available
on the PECL crypto page.
The php-crypto dll is also available in Jan-E Windows builds
on Apache Lounge.
The extension is still in development so the API is not stabilized yet.
All classes are defined in namespace Crypto.
Each base class has an exception class that has the same name and
Exception suffix (e.g. Hash class has HashException. The exception
classes are subclasses of the PHP Exception class. They define
exception code as class constants. Each code also has a different message.
The documentation is devided to sections where can be found documentation of all class methods, constants and other related details:
The PHP based DocBlock documenation for all classes is generated from the extension code. It can be found in docs/Crypto.php. It can be also used for an IDE autocomplete.
The examples can be found in the example directory.
There is lots of features on the TODO list.
The release history can be found HISTORY.md.
