Use Crypt::decrypt()

用 Crypt::decrypt()

$value = Crypt::decrypt($encrypted);

Note : You must decrypt the value with the same key used to encrypt it.

Laravel's encryption routines use Config::get('app.key')for encryption. This happens internally. Since this value is different for every Laravel application then the application that encrypts a value must also decrypt the value.

Or ...

The application must call Crypt::setKey()prior to decryptingto match the key to the value used for encrypting. See Setting the Encryption Key.

注意：您必须使用用于加密它的相同密钥来解密该值。

Laravel 的加密例程Config::get('app.key')用于加密。这发生在内部。因为这个值对于每个 Laravel 应用程序都是不同的，所以加密一个值的应用程序也必须解密这个值。

或者 ...

应用程序必须Crypt::setKey()在decrypting将密钥与用于加密的值匹配之前调用。请参阅设置加密密钥。

To Encryption use

加密使用

Crypt::setKey($key);

This key will be used for subsequent Crypt::encrypt()and Crypt::decrypt()calls.

该密钥将用于后续Crypt::encrypt()和Crypt::decrypt()电话。
