饮食贵在节,读书贵在精,锻炼贵在恒,节饮食养胃,多读书养胆,喜运动延生!人生需要有目标,有追求,然有所以。
本文实例讲述了PHP实现的AES双向加密解密功能。分享给大家供大家参考,具体如下:
<?php /* * Created on 2018-9-1 * * To change the template for this generated file go to * Window - Preferences - PHPeclipse - PHP - Code Templates */ /** 用法: Security::encrypt($str,$key); Security::decrypt($str,$key); */ class Security { public static function encrypt($input, $key) { $size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB); $input = Security::pkcs5_pad($input, $size); $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_ECB, ''); $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND); mcrypt_generic_init($td, $key, $iv); $data = mcrypt_generic($td, $input); mcrypt_generic_deinit($td); mcrypt_module_close($td); $data = base64_encode($data); return $data; } private static function pkcs5_pad ($text, $blocksize) { $pad = $blocksize - (strlen($text) % $blocksize); return $text . str_repeat(chr($pad), $pad); } public static function decrypt($sStr, $sKey) { $decrypted= mcrypt_decrypt( MCRYPT_RIJNDAEL_128, $sKey, base64_decode($sStr), MCRYPT_MODE_ECB ); $dec_s = strlen($decrypted); $padding = ord($decrypted[$dec_s-1]); $decrypted = substr($decrypted, 0, -$padding); return $decrypted; } } //用法示例: $str = "www.haodaima.com"; $key = "123456"; echo "原始字符串:".$str."<br/>"; $pwdstr = Security::encrypt($str,$key); echo "加密后:".$pwdstr."<br/>"; $destr = Security::decrypt($pwdstr,$key); echo "解密结果:".$destr; ?>
运行结果:
原始字符串:www.haodaima.com
加密后:O0vbyikeZRVnXueCodfSFw==
解密结果:www.haodaima.com
