推荐答案
APP_KEY用于加密，而不用于散列.您在应用程序中加密的每个数据都在后台使用APP_KEY.请记住，加密数据可以解密，但散列数据不能解密.
APP_KEY is used for encryption and not hashing. Every Data you encrypt in your application is using APP_KEY behind the scene. Do remember that encrypted data can be decrypted but hashed data cannot be decrypted.
一个常见的对APP_KEY的误解是它与密码哈希相关，事实并非如此.这是证明.
A common misconception of APP_KEY is that it is related to Password hashing, the truth is it's not. and here is the proof.
您可以在上面的推文中看到APP_KEY与 HASHED 数据无关
You can see in the above tweet that APP_KEY has nothing to do with HASHED data
