问题 From searching all around, I can find a number of links referencing similar issues, but nothing is quite working, its driving me mad.... Can someone please give me a step by step guide on how to write the following PHP code in Objective C. We are creating some web service calls, which require encrypted content, and we have only been given PHP encrypt sample. To be clear we do not want to un-encrypt, we want to mirror this encryption process in IOS. Many thanks function encrypt($plainText) {

php using mcrypt_create_iv

由 ▼魔方 西西 提交于 2019-12-08 03:24:30
问题 I want to create a random ints and strings in PHP and so I decided to use mcrypt_create_iv. It is written in manual that it uses /dev/random and /dev/urandom for randomness but I can't find a simple tutorial on how to generate random Int and String using this function. I tried some code but this function gives me unreadable characters. So please can you give me a simple example of how properly I can use it? 回答1: If you want to generate random numbers, use mt_rand: $random = mt_rand(0, 999999)

Mcrypt扩展库可以实现加密解密功能，就是既能将明文加密，也可以密文还原。 1.安装PHP加密扩展Mcrypt 要使用该扩展，必须首先安装mcrypt标准类库，注意的是mcrypt软件依赖libmcrypt和mhash两个库。 2.PHP加密扩展库Mcrypt的算法和加密模式 Mcrypt库支持20多种加密算法和8种加密模式，具体可以通过函数mcrypt_list_algorithms()和mcrypt_list_modes()来显示，结果如下： Mcrypt支持的算法有：cast-128 gost rijndael-128 twofish arcfour cast-256 loki97 rijndael-192 saferplus wake blowfish-compat des rijndael-256 serpent xtea blowfish enigma rc2 tripledes Mcrypt支持的加密模式有：cbc cfb ctr ecb ncfb nofb ofb stream 这些算法和模式在应用中要以常量来表示，写的时候加上前缀MCRYPT_和MCRYPT_MODE_来表示，如下面Mcrypt应用的例子： DES算法表示为MCRYPT_DES; ECB模式表示为MCRYPT_MODE_ECB； 3.PHP加密扩展库Mcrypt应用 先看一个例子

http://my.oschina.net/adamboy/blog Mcrypt扩展库可以实现加密解密功能，就是既能将明文加密，也可以密文还原。 1.PHP加密扩展库Mcrypt安装 在标准的PHP安装过程中并没有把Mrcypt安装上，但PHP的主目录下包含了libmcrypt.dll和libmhash.dll文件 (libmhash.dll是Mhash扩展库，这里可以一起装上)。首先，将这两个文件复制到系统目录windows\system32下，然后在 PHP.ini文件中按Ctrl+F快捷键跳出查找框，并找到；extension=php-mcrypt.dll和; extension=php_mhash.dll这两个语句，接着将前面的“；”去掉；最后，保存并重启Apache服务器即可生效。 2.PHP加密扩展库Mcrypt的算法和加密模式 Mcrypt库支持20多种加密算法和8种加密模式，具体可以通过函数mcrypt_list_algorithms()和mcrypt_list_modes()来显示，结果如下： Mcrypt支持的算法有：cast-128 gost rijndael-128 twofish arcfour cast-256 loki97 rijndael-192 saferplus wake blowfish-compat des rijndael-256

升级 php 7.2 后，使用微信提供的加解密代码时，提示 call to undefined function mcrypt_module_open() ； 查阅相关资料知晓，mcrypt 扩展从 php 7.1.0 开始废弃；自 php 7.2.0 起，会移到 pecl。 安装 mcrypt 扩展 环境：centos 7 1.yum 安装依赖包： yum install libmcrypt libmcrypt-devel mcrypt mhash 2.在 php 官网下载 mcrypt 包，php 扩展官网 # wget http://pecl.php.net/get/mcrypt-1.0.1.tgz # tar xf mcrypt-1.0.1.tgz # cd mcrypt-1.0.1 3.编译安装 mcrypt 进入到php安装目录 # /usr/local/php/bin/phpize # ./configure --with-php-config=/usr/local/php/bin/php-config && make && make install 4.在php.ini加上扩展即可 extension=mcrypt.so 5.重启 php-fpm /etc/init.d/php-fpm restart #可以根据实际情况修改，你也可能是/usr/local/php

php mcrypt equivalent for sagepay on a windows server

由 天大地大妈咪最大 提交于 2019-12-07 19:31:30
Our company primarily used vbscript until fairly recently, when we started changing to PHP. Upon trying to integrate a SagePay form kit into one of our projects I came across this obstacle. We are on a windows 2008 server, and this cannot be changed. The server does not contain the mcrypt library and our server host will not install it due to it being a shared platform. The problematic line comes from a SagePay form kit that you use to pay for things with SagePay. Hopefully some of you will be familiar with these. The line in question is: //** perform encryption with PHP's MCRYPT module

Migrating mcrypt with Blowfish and ECB to OpenSSL

由 ↘锁芯ラ 提交于 2019-12-07 16:25:20
问题 I can't for the life of me figure out how to migrate my legacy mcrypt code to OpenSSL. I got it working for Blowfish with CBC and for Rijndael with CBC, but Blowfish with ECB is eluding me. And yes, I read Moving from mcrypt with Blowfish & ECB to OpenSSL and I tried zero-padding the data, not zero-padding the data, zero-padding the key, cycling over the key and any combination of them and nothing seems to work. This is my code: <?php function encrypt_with_mcrypt($data, $key) { return mcrypt
