This library provides you a handful set of useful helper methods and classes related to security.
use \PSL\Encrypter;
$confidentalText = 'I am using PSL';
$cipherText = Encrypter::encrypt(MCRYPT_RIJNDAEL_128, $confidentalText);
// $cipherText is an instance of \PSL\CipherText.
// To extract, do something like this:
$key = $cipherText->key;
$plainText = Encrypter::decrypt($cipherText, $key);
// $plainText is now same as $confidentalText.use \PSL\Randomizer;
$data = Randomizer::getRandomBytes(32); // 32 bytes.
$randomFloat = Randomizer::getRandomFloat();Things like random float generation is more conplex than what it might seem initially and therefore it's nice to be able to use a library for that.
use \PSL\KeyPair;
use \PSL\Certificate;
$keyPair = new KeyPair();
$details = array(
"countryName" => "FI",
"stateOrProvinceName" => "Southern Finland",
"localityName" => "Lahti",
"organizationName" => "N/A",
"organizationalUnitName" => "N/A",
"commonName" => "localhost",
"emailAddress" => "kaisellgren-at-gmail.com"
);
$certificate = new Certificate($details, $keyPair);
$certificate->sign();
file_put_contents('my.crt', $certificate->export());
