PHP implements encryption and decryption, and php implements encryption and decryption. This example describes the encryption and decryption processing class implemented by PHP. We will share this with you for your reference. The details are as follows: If you are interested in encryption and decryption, refer to the

Barrier encryption and decryption python implementation (key encryption supported) Fence encryption and decryption is a processing method for short strings. Given the Row number, the Column number is calculated based on the string length to form a square matrix. Encryption process: the plaintext is arranged from top to

Based on previous experience, we usually use the MD5 encryption algorithm, although it can be cracked, but because of its cyclical longer, so I have been using, today learned a new encryption algorithm, secure hashing algorithm, specifically he is not the data encryption algorithm, but the data digital Signature Algorithm , It is not to encrypt the entire data, b

The encryption algorithm is as follows: Copy Code code as follows: function Encrypt ($data, $key) { $key = MD5 ($key); $x = 0; $len = strlen ($data); $l = strlen ($key); for ($i = 0; $i { if ($x = = $l) { $x = 0; } $char. = $key {$x}; $x + +; } for ($i = 0; $i { $str. = Chr (Ord ($data {$i}) + (Ord ($char {$i}))% 256); } Return Base64_encode ($STR); } The decryption algorithm is as follows: Copy Code code as fol

Encryption | data | algorithm using C # Data encryption (i)--Symmetric encryption algorithm The following is about the symmetric encryption algorithm of C # implementation code, you can change the different algorithm according to the need, the article takes Rijndael algorithm for example: Using System; Using Syste

Computers are used for office and study. It is a headache to protect our privacy and security. To protect important documents from being browsed by third parties, Special encryption/hiding tools are usually used to encrypt or hide them. In fact, we can directly encrypt text files in the Internet Explorer browser, and it is easy to use -- Encryption principle: Not encrypted by adding a password, but by chang

From: http://snowolf.iteye.com/blog/380034 Next, we will introduce symmetric encryption algorithms. The most common is des data encryption algorithms.Des Des-Data Encryption Standard, which is the data encryption algorithm. It was published by IBM in 1975. The DES algorithm has three entry parameters: Key, data, and mo

Full version of MD5 Encryption Algorithm in Java, javamd5 Encryption Algorithm Some data is inevitably encrypted during Java software development. Therefore, Java provides its own MessageDigest to implement text encryption algorithms, the following is an example of the MD5 encryption tool code for text

I have not found any good DES encryption code for a long time. It is no wonder that a blogger said that he had not found himself for a long time. Http://www.iteye.com/topic/422575 But it seems that he said that the encrypted plaintext will go wrong, so I did not dare to try it out. In addition, I downloaded one from Tiandi, and found that the function was still possible. It seems that I switched the js version. However, the

Complete example of php aes encryption algorithm, phpaes Encryption Algorithm This example describes the AES Encryption Algorithm of PHP. We will share this with you for your reference. The details are as follows: PS: if you are interested in encryption and decryption, refer to the online tools on this site: Online Pa

We have introduced the core implementation principles of mainstream double-layer encryption shells,At the same time, we mentioned compatibility and simplified the encryption Shell Core while considering the security.This article mainly discusses security and compatibility considerations. Security mainly deals with two types of scammers.1. Static Analysis shellingFor this type, the effective method is to i
