Mobile phone typing is really troublesome, so I will not directly provide instances for some simple or too complex code. 1. Not a method-add commentsAdd unnecessary comments without signature. Code omitted 2. case-insensitive Mixing Ignore case sensitivity using VBS 3. Mixing branches and peers Use the colon (:) to connect multiple lines of code as one line 4. One row is divided into multiple rows Use the hyphen (_) to write a row into multiple rows. 5. execute Functions Copy codeThe Code i

Development encountered MD5 encryption inconsistency problem, the exclusion of context encoding, encryption content issues.Crawled all kinds of information, and finally found the reason./**MD5 encryption of strings*/ Private Staticstring encodeByMD5 (String originstring) {if(Originstring! =NULL) { Try{//creates a summary of information with the spec

Mobile phone typing is really troublesome, so some simpler or too complex code I do not directly provide an example. 1, not the method of the method--Add notes Add some rules useless annotations without signatures. Code slightly 2. Mixed case and writing Use VBS to ignore case 3, the branch and the colleague mixes uses Use a colon (:) to connect multiple lines of code to one line 4, one line divided more than one line Use a continuation character (_) to write a line more than one l

PHP uses OpenSSL for RSA encryption, if the plaintext to be encrypted is too long error, workaround: Encrypt the time 117 characters to encrypt once, and then all the cipher stitching into a cipher text, the decryption time needs 128 characters to decrypt, and then splicing into data.Encryption:/** * Encryption * @param $originalData * @return string|void * //*function Encrypt ($originalD

The encryption algorithm is as follows: Copy CodeThe code is 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 the Code code as follows:function Decrypt ($data

PHP commonly used hash encryption function, Phphash encryption In this paper, we describe the commonly used hash encryption function in PHP. Share to everyone for your reference. The specific analysis is as follows: Copy the Code code as follows: $hash _list=hash_algos (); Returns the list of registered hash rules Print_r ($hash _list); Show results Create a fil

PHP string encryption and decryption function, php string encryption and decryption /*************************************** * ***************************** Function Name: encrypt function: encryption and decryption string usage: encryption: encrypt ('str', 'E', 'nowamagic '); decryption: encrypt ('encrypted string ',

Tutorial on encryption folder and encryption folder Sometimes we want to keep a little bit of privacy in our computer, and we want to set a password for some files. We only need to enter a password for access, just like in our QQ space album, many of my friends like to set a password for their album and only tell them to visit. How can I set a password for folders on our computer? This article will share

PHP implementation of the QQ space G_TK encryption algorithm, G_TK encryption algorithm This paper introduces the implementation of PHP QQ space G_TK encryption algorithm. Share to everyone for your reference. Specific as follows: //G_TK calculates function getgtk ($skey) {$hash = 5381; for ($i =0; $i Hopefully this article will help you with your PHP p

PHP implementation of RSA encryption class instance, PHPRSA encryption instance In this paper, we describe the RSA encryption class implemented by PHP. Share to everyone for your reference. The specific analysis is as follows: Signing, checking, asymmetric, and decrypting with OpenSSL is required to be used with the files of the certificates of the "." (Crt and

PHP implementation of cookie encryption method, Phpcookie encryption In this paper, we explain how PHP implements cookie encryption. Share to everyone for your reference. The implementation method is as follows: Copy CodeThe code is as follows: Class Cookie{/*** Decrypt a cookie that has already been encrypted** @param string $encryptedText* @return String*/priv

Problem Description:Des encryption is used recently and is consistent with the results of Java's cipher class encryption. The cliper of Java has not been studied, but in work cipher generates a string based on the Des/cbc/pkcs5padding encryption method.In comparison, this string is formatted directly with the NSData generated by OC

That is, at the time of user registra

. NET MD5 encryption and decryption code parsing, md5 encryption and decryption MD5 introduction: It is used to compress large-capacity information into a confidential format (that is, to convert a byte string of any length into a large integer) before signing a private key using the digital signature software ). Whether MD2, MD4, or MD5, they all need to obtain a random length information and generate a 12

C # DES encryption class, 16-bit encryption ., This Encryption Class is self-written because it is not the same as the DES encryption written in java. It is finally the same as Java encryption, and solves the different problems after enc
