laravel的cookie并不简单

背景：

在之前的文章中，我已经阐述了laravel的cookie产生的过程，那laravel的cookie在响应到客户端之前，又经历了什么呢？

laravel的cookie生成以后，在响应到客户端之前，会经过encrypt的过程，encrypt的加密逻辑定义在src/Illuminate/Encryption/Encrypter.php

    public function encrypt($value, $serialize = true)
    {
        $iv = random_bytes(openssl_cipher_iv_length(strtolower($this->cipher)));

        $value = self::$supportedCiphers[strtolower($this->cipher)]['aead']
            ? \openssl_encrypt(
                $serialize ? serialize($value) : $value,
                strtolower($this->cipher), $this->key, 0, $iv, $tag
            )
            : \openssl_encrypt(
                $serialize ? serialize($value) : $value,
                strtolower($this->cipher), $this->key, 0, $iv
            );

        if ($value === false) {
            throw new EncryptException('Could not encrypt the data.');
        }

        $iv = base64_encode($iv);
        $tag = base64_encode($tag);

        $mac = self::$supportedCiphers[strtolower($this->cipher)]['aead']
            ? '' // For AEAD-algoritms, the tag / MAC is returned by openssl_encrypt...
            : $this->hash($iv, $value);

        $json = json_encode(compact('iv', 'value', 'mac', 'tag'), JSON_UNESCAPED_SLASHES);

        if (json_last_error() !== JSON_ERROR_NONE) {
            throw new EncryptException('Could not encrypt the data.');
        }

        return base64_encode($json);
    }
