Package encrypter-bundle
Short Description A Symfony bundle to encrypt and decrypt data using AES-256-CBC encryption.

FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package encrypter-bundle
Encrypter Symfony Bundle
Purpose
The Encrypter Bundle provides a simple and secure way to encrypt and decrypt data using the AES-256-CBC encryption algorithm. This bundle is designed for Symfony applications, allowing developers to protect sensitive information with ease. With built-in support for key generation and salt handling, the Encrypter Bundle helps ensure that your data remains secure.
Features
- Secure Encryption: Uses AES-256-CBC for data protection.
- Key Management: Supports random key and salt generation.
- Easy Integration: Seamlessly integrates with Symfony applications.
Installation
To install the Encrypter Bundle, run the following command:
Configuration
To configure the Encrypter Bundle, you need to create a configuration file. Follow these steps:
-
Create the Configuration File: Navigate to the
config/packagesdirectory of your Symfony project and create a new file namedencrypter.yaml. - Add Configuration Content: Open the newly created encrypter.yaml file in your text editor and add the following content:
Ensure that the secret key is either 16, 32, or 64 bytes long. This key will be used for encryption and decryption operations.
Available Methods
The Encrypter Bundle provides several methods for encryption, decryption, key generation, and salt generation. Below is a list of each method along with a brief description:
encrypt(string $data, ?string $salt = null): string
Encrypts the given data using the AES-256-CBC encryption algorithm.
-
Parameters:
string $data: The plaintext data to encrypt.string|null $salt: An optional salt to use for key derivation.
- Returns: The encrypted data, encoded in Base64 format, including the initialization vector (IV).
decrypt(string $data, ?string $salt = null): string
Decrypts the given encrypted data.
-
Parameters:
string $data: The encrypted data to decrypt.string|null $salt: An optional salt that was used during encryption.
-
Returns: The original plaintext data.
- Throws: An exception if decryption fails.
generateEncryptionKey(int $length = 32): string
Generates a random encryption key.
-
Parameters:
int $length: The desired length of the encryption key in bytes. Valid lengths are 16, 32, or 64 bytes. Defaults to 32 bytes.
-
Returns: The generated random encryption key, represented as a hexadecimal string.
- Throws: An exception if the length is not valid.
generateSalt(int $length = 16): string
Generates a random salt.
-
Parameters:
int $length: The desired length of the salt in bytes. Valid lengths are 16, 32, or 64 bytes. Defaults to 16 bytes.
-
Returns: The generated random salt, represented as a hexadecimal string.
- Throws: An exception if the length is not valid.
Usage
To use the Encrypter Bundle in your Symfony application, you can inject the EncrypterInterface into your services or controllers. Here's an example of how you can encrypt and decrypt data:
