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 { 公共功能制造（$ value）{ 返回哈希（'sha1'，$ value）; } 公共功能检查（$ value，$ hashedvalue）{ 返回$ this-> make（$ value）=== $ hashedvalue; } 公共功能需要刻痕（$ hashedvalue）{ 返回false; } }

注册SHA1 HASHER

一旦创建了Shahasher类，我们需要将其注册为Laravel Service容器为默认的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为您的应用程序维护安全的哈希机制。
