php支持中英文的加密解密类代码
本文章分享的这个php加密类是一个可以支持中文和英文的可加密码可解密的php实现类文件,有需要的同学可以参考一下,不过最好把文档编码设置为utf-8.
下面代码保存成MD5Crypt.class.php文件,代码如下:
<?php class MD5Crypt { /** * Enter description here ... * @param unknown_type $str * @return string */ public final static function mdsha( $str ) { $code = substr ( md5 ( $str ), 10 ); $code .= substr ( sha1 ( $str ), 0, 28 ); $code .= substr ( md5 ( $str ), 0, 22 ); $code .= substr ( sha1 ( $str ), 16 ) . md5 ( $str ); return self::chkToken () ? $code : null; } /** * Enter description here ... * @param unknown_type $param */ private final static function chkToken() { return true; } /** * Enter description here ... * @param unknown_type $txt * @param unknown_type $encrypt_key * @return Ambigous <string, boolean> */ private final static function keyED( $txt , $encrypt_key ) { $encrypt_key = md5 ( $encrypt_key ); $ctr = 0; $tmp = "" ; for ( $i = 0; $i < strlen ( $txt ); $i ++) { if ( $ctr == strlen ( $encrypt_key )) $ctr = 0; $tmp .= substr ( $txt , $i , 1 ) ^ substr ( $encrypt_key , $ctr , 1 ); $ctr ++; } return $tmp ; } /** * Enter description here ... * @param unknown_type $txt * @param unknown_type $key * @return string */ public final static function Encrypt( $txt , $key ) { srand ( ( double ) microtime () * 1000000 ); $encrypt_key = md5 ( rand ( 0, 32000 ) ); $ctr = 0; $tmp = "" ; for ( $i = 0; $i < strlen ( $txt ); $i ++) { if ( $ctr == strlen ( $encrypt_key )) $ctr = 0; $tmp .= substr ( $encrypt_key , $ctr , 1 ) . ( substr ( $txt , $i , 1 ) ^ substr ( $encrypt_key , $ctr , 1 )); $ctr ++; } $_code = md5 ( $encrypt_key ) . base64_encode ( self::keyED ( $tmp , $key ) ) . md5 ( $encrypt_key . $key ); return self::chkToken () ? $_code : null; } /** * Enter description here ... * @param unknown_type $txt * @param unknown_type $key * @return Ambigous <string, boolean> */ public final static function Decrypt( $txt , $key ) { $txt = self::keyED ( base64_decode ( substr ( $txt , 32, - 32 ) ), $key ); $tmp = "" ; for ( $i = 0; $i < strlen ( $txt ); $i ++) { $md5 = substr ( $txt , $i , 1 ); $i ++; $tmp .= ( substr ( $txt , $i , 1 ) ^ $md5 ); } //开源代码phpfensi测试数据 return self::chkToken () ? $tmp : null; } /** * Enter description here ... * @var unknown_type */ private static $_key = 'lau' ; } ?>用法,代码如下:
<?php //Code Start define ( 'WORKSPACE' , '.' . DIRECTORY_SEPARATOR ); header ( "Content-Type: text/html; charset=utf-8" ); include_once 'Core/Library/MD5Crypt.class.php' ; $a = MD5Crypt::Encrypt ( "A" , 100 ); echo "EnCode:" . $a , "<br />" ; echo "DeCode:" . MD5Crypt::Decrypt ( $a , 100 ); ?>查看更多关于php支持中英文的加密解密类代码 - php类库的详细内容...
