如何在WAMP中使用MCRYPT_ARCFOUR加密？

本文介绍了如何在WAMP中使用MCRYPT_ARCFOUR加密？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我想在我的PHP代码中使用ARCFOUR算法：I'm trying to use ARCFOUR algorithm in my PHP code:$td = mcrypt_module_open(MCRYPT_ARCFOUR, '', MCRYPT_MODE_CBC, '');$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);mcrypt_generic_init($td, $key, $iv);$output = mcrypt_generic($td, $input);mcrypt_generic_deinit($td);mcrypt_module_close($td);问题是第一行返回警告：and the problem is that the first line returns warning:mcrypt_module_open(): Could not open encryption module 我的设置： 从php_info （）output：From php_info() output:命令configure：...--with-mcrypt = static... command configure: ... "--with-mcrypt=static" ... 如果我是正确的，这意味着我不需要DLL的mcrypt扩展。 If I'm correct it means I do not need a DLL for mcrypt extension. 支持的密码： 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 Supported ciphers: 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 PHP版本5.3.8 PHP version 5.3.8 Wamp 2.2a （32位）Wamp 2.2a (32 bits)感谢您的帮助！推荐答案 从PHP 5.3.6和5.4.0 RC6开始， arcfour ，唤醒和 enigma mcrypt密码需要使用 stream / em>。它们不会初始化任何其他模式，也不能使用任何其他密码使用 stream 模式。As of PHP 5.3.6 and 5.4.0 RC6, the arcfour, wake and enigma mcrypt ciphers require the use of stream mode. They will not initialize any of the other modes, nor can any of the other ciphers use stream mode. 演示代码，使用 @ 现在静默无法打开模块警告：Demo code, with the @ present to silence the "can't open module" warning:foreach(mcrypt_list_algorithms() as $alg) { printf("\n%20s:", $alg); foreach(mcrypt_list_modes() as $mode) { $mc = @mcrypt_module_open($alg, null, $mode, null); if(is_resource($mc)) echo "\t$mode"; else echo "\t!!FAIL!!:$mode"; }}echo "\n";演示输出： cast-128: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream gost: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream rijndael-128: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream twofish: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream arcfour: !!FAIL!!:cbc !!FAIL!!:cfb !!FAIL!!:ctr !!FAIL!!:ecb !!FAIL!!:ncfb !!FAIL!!:nofb !!FAIL!!:ofb stream cast-256: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream loki97: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream rijndael-192: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream saferplus: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream wake: !!FAIL!!:cbc !!FAIL!!:cfb !!FAIL!!:ctr !!FAIL!!:ecb !!FAIL!!:ncfb !!FAIL!!:nofb !!FAIL!!:ofb stream blowfish-compat: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream des: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream rijndael-256: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream serpent: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream xtea: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream blowfish: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream enigma: !!FAIL!!:cbc !!FAIL!!:cfb !!FAIL!!:ctr !!FAIL!!:ecb !!FAIL!!:ncfb !!FAIL!!:nofb !!FAIL!!:ofb stream rc2: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream tripledes: cbc cfb ctr ecb ncfb nofb ofb !!FAIL!!:stream 正在查看 PHP错误49311 ，该问题在2009年未收到任何反馈后被关闭。 RC4 ， WAKE 和谜语被打破。代码演示问题：It looks like you (and I) are seeing PHP bug 49311, which was closed after no feedback in 2009. RC4, WAKE and Enigma are broken.
