Both using symmetric encryption and asymmetric encryption way, always in the front of encryption, the encryption rules directly exposed, so no matter what background, is not do? Is there a big science,

CodePudding user response:

Encryption method is public, so can only rely on the key to ensure safety,
A good encryption method, if there is no key, ciphertext alone and encryption rules to crack into plaintext, it is very difficult to

So the key distribution is the key:
In the asymmetric encryption private key and the symmetric encryption key as long as not been stealing is safe,

CodePudding user response:

If you are a native app you add secret key on the front end should take less than others. If you are a h5 then add the secret key is not to be on the front end need to request the back-end backend to add secret key

CodePudding user response:

Cryptography algorithm in public is safe, secret key by the security

I understand the concept, but with caught tools caught after modify the data, I modify the data, do not need to know how much is the key, I just need to decide according to have good encryption encryption is OK, the backend so normally,
