PHPSecryption - A PHP Class for Encryption and Decryption
=========================================================

[](#phpsecryption---a-php-class-for-encryption-and-decryption)

PHPSecryption is a PHP class that provides encryption and decryption functionality using the OpenSSL library. It uses the Advanced Encryption Standard (AES) algorithm in Cipher-Block Chaining (CBC) mode for secure data encryption.

#### Features

[](#features)

- Strong encryption using AES-256-CBC cipher.
- Supports custom encryption and decryption keys.
- Error handling for key mismatches and invalid encrypted data.
- Simple and easy-to-use API.

#### Installation

[](#installation)

You can install PHPSecryption via Composer using the following command:

`composer require iamjohndev/phpencryption:dev-main`

Alternatively, you can manually download and include the PHPSecryption.php file in your PHP project.

Usage
=====

[](#usage)

Here's an example of how to use PHPSecryption in your PHP code:

```
require 'vendor/autoload.php'; // Add this line if you're using core PHP

use iamjohndev\PHPSecryption;

// Instantiate PHPSecryption with encryption key
$encryptionKey = 'mysecretencryptionkey';
$phpEncryption = new PHPSecryption($encryptionKey);

// Encrypt data
$data = 'Hello, world!';
$encryptedData = $phpEncryption->encrypt($data);

// Decrypt data
$decryptedData = $phpEncryption->decrypt($encryptedData);

// Display results
echo "Original data: $data\n";
echo "Encrypted data: $encryptedData\n";
echo "Decrypted data: $decryptedData\n";
```

You can also set a custom decryption key using the setDecryptionKey() method if you want to use a different key for decryption than the one used for encryption.

```
// Set custom decryption key
$decryptionKey = 'mysecretdecryptionkey';
$phpEncryption->setDecryptionKey($decryptionKey);
```

Error Handling
==============

[](#error-handling)

PHPSecryption provides error handling for key mismatches and invalid encrypted data. If the decryption key does not match the encryption key used, or if the encrypted data is invalid, an exception will be thrown with an appropriate error message.

```
try {
    // Decrypt data with incorrect key
    $invalidDecryptionKey = 'incorrectdecryptionkey';
    $decryptedData = $phpEncryption->decrypt($encryptedData, $invalidDecryptionKey);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage() . "\n";
}
```

Security Considerations
-----------------------

[](#security-considerations)

- Properly manage encryption keys and keep them confidential and protected from unauthorized access.
- Store encrypted data and encryption keys securely with appropriate access controls.
- Validate and sanitize input data to prevent potential security vulnerabilities.
- Regularly audit and review the implementation for security risks.
- Ensure compliance with applicable data protection laws and industry regulations, especially when handling sensitive data.
