Usage
=====

[](#usage)

RSA
---

[](#rsa)

#### Generate Rsa keys

[](#generate-rsa-keys)

> the available key lengths are 1024 and 2048

```
$ openssl genrsa -out rsa_private_key.pem 1024
$ openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

```

#### Encrypt & Sign

[](#encrypt--sign)

- prepare keys

```
$pri = file_get_contents('keys/rsa_private_key.pem');
$pub = file_get_contents('keys/rsa_public_key.pem');
```

- encrypt

```
$rsa = new RSA();
$rsa->setPubKey($pub);
$encodedData = $rsa->encrypt("hello", RSA::OPENSSL_PKCS1_PADDING);

```

- decrypt

```
$rsa = new RSA();
$rsa->setPriKey($pri);
$sourceData = $rsa->decrypt($encodedData, RSA::OPENSSL_PKCS1_PADDING);

```

- sign

```
$rsa = new RSA();
$rsa->setPriKey($pri);
$signedData = $rsa->sign('hello',Rsa::OPENSSL_ALGO_SHA256);

```

- verify

```
$rsa = new RSA();
$rsa->setPubKey($pri);
$result = $rsa->verify('hello',$signedData,Rsa::OPENSSL_ALGO_SHA256);

```

#### Support Params

[](#support-params)

namedefaultvaluePKCS1\_PKCS1\_PADDINGyes1PKCS1\_SSLV23\_PADDING2PKCS1\_NO\_PADDING3PKCS1\_OAEP\_PADDING4#### Tips

[](#tips)

- When OpenSSL is used "OPENSSL\_NO\_PADDING" to padding parameter, you need to manually fill in the original data

```
$str = str_pad("hello", 256); //128 or 256
$rsa = new RSA();
$rsa->setPubKey($pub);
$encodedData = $rsa->encrypt($str, RSA::OPENSSL_NO_PADDING);

```

Other Encryption
----------------

[](#other-encryption)

```
$encryption= new Crypt(['cipher' => 'aes-256-cbc']);
$encode = $encryption->encrypt("hello", 'keyToMyHeart');
$decode = $encryption->decrypt($encode, 'keyToMyHeart');
var_dump([
    $encryption->getIv(),
    $encode,
    $decode
]);

```

```

$en = new Crypt(['cipher' => 'aes-256-cbc']); //des-ede3;
$iv = '0123456789abcdef';
//$iv = $en->makeIv();
$clientSecret = 'nuasndu89382j3d3d9238';

$encode = $en->encrypt("hello", $clientSecret, $iv);
$decode = $en->decrypt($encode, $clientSecret, $iv);

var_dump([
    $en->getIv(),
    $en->ivSize,
    $encode,
    $decode
]);

```

Top contributor holds 100% of commits — single point of failure

How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window.

**Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores.

**Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement.

**Maturity (30%)** — Project age, version count, PHP version support, and release stability.
