```

### Usage

[](#usage)

#### Symmetric encryption/decryption

[](#symmetric-encryptiondecryption)

```
use Smoren\EncryptionTools\Helpers\SymmetricEncryptionHelper;

$data = ["some", "data" => "to", "encrypt"];
$secretKey = uniqid();

$dataEncrypted = SymmetricEncryptionHelper::encrypt($data, $secretKey);
$dataDecrypted = SymmetricEncryptionHelper::decrypt($dataEncrypted, $secretKey);
print_r($dataDecrypted);

$dataEncrypted = SymmetricEncryptionHelper::encrypt($data, $secretKey, 'camellia-256-ofb');
$dataDecrypted = SymmetricEncryptionHelper::decrypt($dataEncrypted, $secretKey, 'camellia-256-ofb');
print_r($dataDecrypted);
```

#### Asymmetric encryption/decryption (RSA-based)

[](#asymmetric-encryptiondecryption-rsa-based)

```
use Smoren\EncryptionTools\Helpers\AsymmetricEncryptionHelper;

$data = ["some", "data" => "to", "encrypt"];
[$privateKey, $publicKey] = AsymmetricEncryptionHelper::generateKeyPair();

$dataEncrypted = AsymmetricEncryptionHelper::encryptByPrivateKey($data, $privateKey);
$dataDecrypted = AsymmetricEncryptionHelper::decryptByPublicKey($dataEncrypted, $publicKey);
print_r($dataDecrypted);

$dataEncrypted = AsymmetricEncryptionHelper::encryptByPublicKey($data, $publicKey);
$dataDecrypted = AsymmetricEncryptionHelper::decryptByPrivateKey($dataEncrypted, $privateKey);
print_r($dataDecrypted);
```

#### Asymmetric signing/verifying (RSA-based)

[](#asymmetric-signingverifying-rsa-based)

```
use Smoren\EncryptionTools\Helpers\AsymmetricEncryptionHelper;
use Smoren\EncryptionTools\Exceptions\AsymmetricEncryptionException;

$data = ["some", "data" => "to", "encrypt"];
[$privateKey, $publicKey] = AsymmetricEncryptionHelper::generateKeyPair();

$signature = AsymmetricEncryptionHelper::sign($data, $privateKey);

try {
    AsymmetricEncryptionHelper::verify($data, $signature, $publicKey);
} catch(AsymmetricEncryptionException $e) {
    // ... handling exception if cannot verify signature
}
```

#### Asymmetric encryption/decryption (RSA-based) for large data

[](#asymmetric-encryptiondecryption-rsa-based-for-large-data)

```
use Smoren\EncryptionTools\Helpers\AsymmetricLargeDataEncryptionHelper;

$data = file_get_contents('file_with_large_data.txt');
[$privateKey, $publicKey] = AsymmetricLargeDataEncryptionHelper::generateKeyPair();

$dataEncrypted = AsymmetricLargeDataEncryptionHelper::encryptByPrivateKey($data, $privateKey);
$dataDecrypted = AsymmetricLargeDataEncryptionHelper::decryptByPublicKey($dataEncrypted, $publicKey);
print_r($dataDecrypted);

$dataEncrypted = AsymmetricLargeDataEncryptionHelper::encryptByPublicKey($data, $publicKey);
$dataDecrypted = AsymmetricLargeDataEncryptionHelper::decryptByPrivateKey($dataEncrypted, $privateKey);
