使用sha1加密4：raravel 4中的逐步指南

Implement the make(), check(), and needsRehash() methods as follows:

class SHAHasher implements Illuminate\Hashing\HasherInterface { 公共功能製造（$ value）{ 返回哈希（'sha1'，$ value）; } 公共功能檢查（$ value，$ hashedvalue）{ 返回$ this-> make（$ value）=== $ hashedvalue; } 公共功能需要刻痕（$ hashedvalue）{ 返回false; } }

註冊SHA1 HASHER

一旦創建了Shahasher類，我們需要將其註冊為Laravel Service容器為默認的Hasher。 directory.

Register the SHAHasher class using the following code:

1. class SHAHashServiceProvider extends Illuminate\Support\ServiceProvider { 公共功能寄存器（）{ $ this-> app ['hash'] = $ this-> app-> share（function（）{ 返回新Shahasher（）; }）; } }
2. Updating the Application Configuration

class SHAHasher implements Illuminate\Hashing\HasherInterface {

    public function make($value) {
        return hash('sha1', $value);
    }

    public function check($value, $hashedValue) {
        return $this->make($value) === $hashedValue;
    }

    public function needsRehash($hashedValue) {
        return false;
    }

}

In app/config/app.php, remove the following line from the providers array：

'SHAHashServiceProvider',

1. Conclusion

By following these steps, you can effectively use SHA1 encryption instead of BCrypt in Laravel 4. This allows you to integrate your application with legacy systems or external services that require SHA1 authentication while為您的應用程序維護安全的哈希機制。
