Introduction

The Encryption Module offers secure data encryption and decryption through functions like getEncryptedData and getDecryptedData. Additionally, it facilitates token creation. With a focus on simplicity and security, it seamlessly integrates into applications, ensuring data security without compromising ease of use.

How To Encrypt

This guide outlines the process of encrypting data using the Encryption module in Do Framework.

Define Data to Encrypt
```
$data_to_encode = "Hello World";
```
- Set the variable $data_to_encode to the data you want to encrypt. Replace "Hello World" with the actual data you intend to encrypt.
Initialize Encryption Object
```
$encryption_object = new Encryption();
```
- Create a new instance of the Encryption class. This class is assumed to handle encryption operations.
Set Data for Encryption
```
$encryption_object->setString($data_to_encode);
```
- Call the setString() method on the $encryption_object instance, passing the data to be encrypted ($data_to_encode) as an argument.
Retrieve Encrypted Data
```
$encrypted_string = $encryption_object->getEncryptedData();
```
- Call the getEncryptedData() method on the $encryption_object instance. This method is expected to perform encryption on the previously set string and return the encrypted data. The encrypted data is stored in the variable $encrypted_string.

// Step 1: Define Data to Encrypt
$data_to_encode = "Hello World";

// Step 2: Initialize Encryption Object
$encryption_object = new Encryption();

// Step 3: Set Data for Encryption
$encryption_object->setString($data_to_encode);

// Step 4: Retrieve Encrypted Data
$encrypted_string = $encryption_object->getEncryptedData();

This code snippet demonstrates how to encrypt data using the Encryption module provided by the Do framework. Each step is accompanied by a comment to explain its purpose in the encryption process.

How To Decrypt

This guide outlines the process of decrypting data using the Encryption module in Do Framework.

Define Data to Decrypt
```
$data_to_decrypt = "YEwsEjrTMu7m3bliq0aqTg==";
```
- Set the variable $data_to_decrypt to the encrypted data you want to decrypt.
Initialize Decryption Object
```
$decryption_object = new Encryption();
```
- Create a new instance of the Encryption class. This class is assumed to handle decryption operations.
Set Data for Decryption
```
$encryption_object->setString($data_to_encode);
```
- Call the setString() method on the $decryption_object instance, passing the data to be decrypted ($data_to_decrypt) as an argument.
Retrieve Decrypted Data
```
$decrypted_data = $decryption_object->getDecryptedData();
```
- Call the getDecryptedData() method on the $decryption_object instance. This method is expected to perform decryption on the previously set encrypted string and return the decrypted data. The decrypted data is stored in the variable $decrypted_data.

// Step 1: Define Data to Decrypt
$data_to_decrypt = "YEwsEjrTMu7m3bliq0aqTg=="; // Encrypted data to be decrypted

// Step 2: Initialize Decryption Object
$decryption_object = new Encryption(); // Initialize Decryption object

// Step 3: Set Data for Decryption
$decryption_object->setString($data_to_decrypt); // Set data for decryption

// Step 4: Retrieve Decrypted Data
$decrypted_data = $decryption_object->getDecryptedData(); // Retrieve decrypted data

How to Build a Token

This guide outlines the process of building a token using the Encryption module in Do Framework.

Define Token Data
```
// Define the data to be included in the token
$token_data = array(
    "user_id" => $user_id, // User ID
    "email" => $email, // Email
    "expire" => $expire_int // Expiry time
);
```
- Define an associative array $token_data containing the information you want to include in the token. This may include user ID, email, and expiration time, among other relevant data.
Build the Token
```
// Build the token using the Encryption class method
$token = Encryption::buildToken($token_data);
```
- Call the buildToken() method from the Encryption class, passing the token data array as an argument. This method will generate the token based on the provided data.

// Define the token data
$token_data = array(
    "user_id" => $user_id,
    "email" => $email,
    "expire" => $expire_int
);

// Build the token
$token = Encryption::buildToken($token_data);

This code snippet demonstrates how to build a token using the Encryption module provided by the Do framework. Each step is accompanied by a comment to explain its purpose in the token build process.

How to Decode a Token

This guide outlines the process of decoding a token using the Encryption module in Do Framework.

Decode the Token
```
// Decode the token using the Encryption class method
$decoded_data = Encryption::decodeToken($token);
```
- Call the decodeToken() method from the Encryption class, passing the token string as an argument. This method will decode the token and return the decoded data.
Access Decoded Data
```
// Access decoded data
$user_id = isset($decoded_data['user_id']) ? $decoded_data['user_id'] : null;
$email = isset($decoded_data['email']) ? $decoded_data['email'] : null;
$expire = isset($decoded_data['expire']) ? $decoded_data['expire'] : null;
```
- Access the decoded data using keys corresponding to the data you encoded into the token. In this example, $decoded_data['user_id'], $decoded_data['email'], and $decoded_data['expire'] correspond to the user ID, email, and expiration time respectively.
