Irreversible encryption functions: md5 (), crypt ()Md5 () is used to calculate MD5. Syntax: string md5 (string str );Crypt () encrypts the string with the standard DES module of UNIX. This is a one-way encryption function and cannot be decrypted. To
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)
Because I like SQL injection, and I have detected many websites before and after. ASPPHPJSP found that the MD5 encryption algorithm is basically used. it is said that MD5 cannot be undone, but MD5 cannot be reversed, but it can be cracked by brute
I have not updated my blog for more than half a year, and I am very sorry for my comments and questions on my blog. I thought I was about to leave the IT industry. I have been working on outsourcing for nearly two years. Every day, I am catching up
The irreversible cryptographic functions are: MD5 (), Crypt ()
MD5 () is used to compute MD5. Syntax is: string MD5 (string str);
Crypt () encrypts the string with the standard UNIX encryption DES module. This is a one-way cryptographic function

This article describes in detail how to use the crypt () function to encrypt php Data, interested friends can refer to this article for details about using the crypt () function in php for encryption, which has some reference value. interested
The crypt () function can complete one-way encryption functions.
String crypt (String str [, string salt]);
STR: is a string that needs to be encrypted; salt: The interference string used for encryption. If the salt is omitted, a disturbance

The crypt () function returns a string that is encrypted using the DES, Blowfish, or MD5 algorithms.
On different operating systems, the function behaves differently, and some operating systems support more than one type of algorithm. At
This problem is much easier than its brother, "843-crypt Kicker ". just find the key line and get the translate table from it will do all the job. I generate a "signature" for the key line to make the search easier. by the way, pay attention to
