Encrypting and Decrypting Text Using RSA in PHP without Padding
Question:
Is there a PHP 5.3 class that facilitates RSA encryption and decryption without employing padding?
Additionally, I am in possession of private and public keys, along with the values for p, q, and modulus.
Answer:
For your PHP 5.3 requirements, phpseclib offers a convenient pure PHP implementation of RSA. Here's how you can utilize it:
<?php
include('Crypt/RSA.php');
$privatekey = file_get_contents('private.key');
$rsa = new Crypt_RSA();
$rsa->loadKey($privatekey);
$plaintext = new Math_BigInteger('aaaaaa');
echo $rsa->_exponentiate($plaintext)->toBytes();
?>
Utilizing this code snippet, you can seamlessly encrypt and decrypt text using RSA without any padding.

How to execute an UPDATE query in php
Aug 24, 2025 am 05:04 AM
Using MySQLi object-oriented method: establish a connection, preprocess UPDATE statements, bind parameters, execute and check the results, and finally close the resource. 2. Using MySQLi procedure method: connect to the database through functions, prepare statements, bind parameters, perform updates, and close the connection after processing errors. 3. Use PDO: Connect to the database through PDO, set exception mode, pre-process SQL, bind parameters, perform updates, use try-catch to handle exceptions, and finally release resources. Always use preprocessing statements to prevent SQL injection, verify user input, and close connections in time.
