Recently in the project, the issue of DES Encryption and decryption was encountered.Scene is the Android app side with Des encryption, PHP this side need to decrypt. No prior contact with Des this encryption and decryption algorithm, but think there will definitely be demo. So Baidu, search the code to use. Online code is also a mixed bag, and finally test the PH
Simple implementation of PHP encryption technology and php encryption technology
1. MD5 Encryption
Take a logon page as an example:
I remember that MD5 is also used for comparison, so the password is saved when there is a database.
mysql> SELECT * FROM user;+----+----------+----------------------------------+| id | username | password |+----+--------
Before everyone has summed up, based on the key exchange DH algorithm, now for you to introduce a factor decomposition based RSA algorithm, this encryption algorithm has two implementation forms: 1, public key encryption, private key decryption, 2, private key encryption, public key decryption. The following for you to analyze the implementation of code, compared
Examples of typical discuz encryption methods for php encryption and discuz details

Encryption of common Asp. Net tools-asymmetric encryption RSA algorithm, asp. netrsa
After several years of entering the programmer industry, there have been gains (enhanced technology) and efforts (time and sub-health status) in the past few years ). Of course, there is no regret, and the code is still long !!!
On The Way, never stop !!!
In the development process, I have also accumulated some exp
The difference between 16-bit MD5 encryption and 32-bit MD5 encryptionMD5 encryption is usually a 32-bit encoding, and in many places will use 16-bit encodingWhat difference do they have?16-bit encryption is to extract the middle 16 bits from the 32-bit MD5 hash!Actually cracked 16-bit MD5 hash is slower than cracking 32-bit MD5 hashBecause he has one more step,
Several common encryption functions in PHP and common encryption functions in PHP
MD5 encryption:
String md5 (string $ str [, bool $ raw_output = false])
1. by default, md5 () returns a hash value in the hexadecimal format of 32 characters. It accepts two parameters: the first is the string to be encrypted, and the second is the Boolean value of raw_output, the d
PHP implementation AES256 Encryption algorithm example, AES256 encryption algorithm Example
In this paper, the method of implementing AES256 encryption algorithm in PHP is described, and it is a more common encryption algorithm. Share to everyone for your reference. Specific as follows:

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After fi
1. Overview of cryptographic algorithmsThe encryption algorithm can be divided into reversible and non-reversible encryption depending on whether the content is restored.Reversible encryption can be divided into symmetric and asymmetric encryption according to whether the same key is used for
PHP, Java des encryption and decryption instances, DES encryption and decryption
Des encryption is a symmetric encryption in the Internet application of a more than one encryption method, PHP through the MCrypt extension library to support DES
First, prefaceWith the broadcast technology hot, all the Live app, the early live app's various request protocol parameter information did not do any encryption measures, but slowly someone began to use the back door began to brush powder attention tool, you can make a new small Hua Dan minute into the net red. So somewhere in this problem, the live app starts encrypting the network request parameters. So that is the focus of this article analysis. Th
