Php implements crypt encryption for user registration passwords, and users register crypt
The example in this article shares the encryption of the php user registration password for your reference. The details are as follows:
I. Code
1. conn. php
2. index. php
3. index_ OK .php
Ii. Running result
After successful registration, the database displays the following:
The above is all the content of this art

How to Use DM-Crypt to encrypt a Linux File System?
Readers often ask us how to implement a file system encryption method for Linux. Before discussing this topic in depth, I would like to clarify two points:
First, it is difficult to find enough information on the Internet. So I will introduce you to a few really great resources that are hard to find (actually several tutorials ).
Second, it is important to understand the technical details of this is
Learn crypt ()
As long as there is a bit of experience with non-Windows platform readers can be quite familiar with crypt (), this function is called one-way encryption function, it can encrypt some plaintext, but not in turn, the password is converted to the original plaintext. The crypt () function is defined as follows.
String
The crypt () function returns a string encrypted with DES, Blowfish, or MD5. In different operating systems, the behavior of this function is different. Some operating systems support more than one algorithm type. During installation, PHP checks what algorithms are available and used.

BKJIA quick translation: When we use the Red Hat Kickstart script or useradd or other methods to write things, we often need to use the password format encrypted by the crypt command. Is there any other way to generate a password in this format? In fact, there are many methods.
We can use the mkpasswd command: this command is used to generate a password in crypt format:
mkpasswd
After the command is entered
Functions of the PHP function crypt. We know that the data encryption function is available. today we will introduce one of the functions that can implement data encryption: the PHP function crypt (). As the PHP function crypt (), we know that there is a function to implement data encryption, today we will introduce one of the functions that can implement data en
Data encryptionData encryption uses cryptography technology to encrypt information, realize the concealment of information, and thus play a role in protecting information security. It uses the encryption algorithm and the encryption key to process the original plaintext file or data, so that its written unreadable code, known as "ciphertext", to achieve the security of data protection.Crypt () functionThe crypt () function returns a string that is enc
This command is used to generate the password in the crypt format:mkpasswdAfter you enter a command, the program asks for a password and then generates a string in crypt format.If you are using an Apache Web server, you can also use HTPASSWD:Htpasswd-nd UserIt doesn't matter what the user name is, we are concerned with the password. This command will output a string in User:password format, and it will be O

Basic knowledgeThe password for the Linux user is implemented by the function crypt (). Crypt () is a cryptographic function (password encryption, plaintext into ciphertext), the function is based on the Data Encryption Standard (DES,DATA encryption) algorithm and DES-based other variant algorithm, the function does not rely on computer hardware to achieve data encryption. The DES algorithm is only suitable
