Topic One: Why is HTTPS safe1. Why is HTTP not secure?The HTTP protocol belongs to the plaintext transmission protocol, the interaction process and data transmission are not encrypted, the communication parties have not carried out any

Public key, private key:exists in asymmetric encryptionKey:exists in symmetric encryptionThe CER file holds the public key and some information about the user (in fact, the digital certificate mentioned below)P12 (PFX) file (a backup of CER, for

A PHP developer should be primarily familiar with the following encryption methods: L Symmetric encryption L Asymmetric encryption (public key) L hash function (Information Digest) L Information Verification Code This appendix focuses on

The encryption function of PHP Security programming data encryption has become more and more important in our lives, especially considering the large volume of transactions and transmitted data on the network. If you are interested in using security

In the previous article we analyzed the principle of Sha, and took SHA1 as an example to implement the relevant algorithm, in this one we will further analyze SHA2 and realize it.1 , SHA Brief IntroductionAs we have already explained in the previous

As software developers, one of the most important responsibilities is to protect users' personal information. If users have no technical knowledge, they have no choice but to trust us when using our services. Unfortunately, when we look into
