2. In addition, for the sake of security, if all use the same key, as long as one is cracked, it means that all are cracked and the meaning of encryption is lost.
3. Generally, the encryption of digital signature, ciphertext and other data will adopt different encryption types according to needs, which means public key password or private key password. Private key cryptography generally has many keys, complicated calculation and is not easy to crack, but it is not suitable for encrypting large amounts of data. Although public key cryptography can quickly encrypt a large number of transmitted data, it is not as secure as private key. In addition, we should also consider the influence of weak keys or semi-weak keys generated in different environments on the security of encrypted data.
In short, don't sacrifice the little starlight that brings peace of mind to people in unstable networks because it is troublesome to write or difficult to understand. Hehe, I hope these are useful to you ~
