rsa签名算法
-------

[](#rsa签名算法)

签名算法采用SHA256进行哈希，并使用私钥对哈希值进行加密获得签名
验证签名时，使用公钥解密后获得哈希值和参数哈希后的字符串进行对比验签

> 建议使用长度为2048以上的公私钥对，各个长度的保密年限对比下表附出，超过保密年限的密钥长度不保证安全性

密钥长度保密年限10242010204820303072204076802080153602120#### 安装

[](#安装)

```
composer require "json-chan/rsa-sign"

```

#### 签名

[](#签名)

```
require "vendor/autoload.php";

use JoseChan\RsaSign\PrivateKey;
use JoseChan\RsaSign\Signature;

$private_key = new PrivateKey($key_string);

$sign = Signature::sign($string, $private_key);
```

#### 验签

[](#验签)

```
require "vendor/autoload.php";

use JoseChan\RsaSign\PublicKey;
use JoseChan\RsaSign\Signature;

$public_key = new PublicKey($key_string);

$result = Signature::verify($string, $sign, $public_key);
```
