openssl_decrypt代替mcrypt_decrypt做可逆加密解密代替方案

2023-1-31 菜鸟站长

mcrypt_encrypt 超过php7.1舍弃了就，php7.1屏蔽错误还可以用。升级php版本就必须使用openssl_decrypt代替之前使用 mcrypt_encrypt 这个函数做的加密解密。下面是自己的老项目升级加密解密的代替方案，仅供参考。

			<?php

			//php7.1中屏蔽错误 mcrypt_decrypt还能继续使用说明没有移除 

			error_reporting(0);

			//aes的解密方案1

			$miwen1 = "F6D6F143A7ACBCF0FCFCF542C638836C4AEA9BC33B9A5CE867A5102E0770F62D8D76EFBE1EF023790D48058EDACF5847D5864A3331FE0F0E4BA1B81B774EB294";

			$key1 = 'OKLU520XJB09906H'; //秘钥

			$iv1 = $key1;

			$decrypted1 = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key1, hex2bin($miwen1), MCRYPT_MODE_CBC, $iv1); //秘钥解密

			//处理json

			$json_str1 = str_replace("\u0000", "", json_encode($decrypted1));

			$arr1 = json_decode(json_decode($json_str1), true);

			//获取账号密码

			print_r($arr1);

			$miwen2 = "F6D6F143A7ACBCF0FCFCF542C638836C4AEA9BC33B9A5CE867A5102E0770F62D8D76EFBE1EF023790D48058EDACF5847D5864A3331FE0F0E4BA1B81B774EB294";

			$key2 = "OKLU520XJB09906H";

			$iv2 = $key2;

			//OpenSSL 解密 或者OPENSSL_NO_PADDING

			$decrypted2 = openssl_decrypt(hex2bin($miwen2), "aes-128-cbc", $key2, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv2);

			//echo json_encode($de_data);

			//有特殊字符再json_encode之后能否发现，然后过滤掉"[{\"T\":\"638107685499086584\",\"P\":\"OT4pQ42TiE6jDPy6\",\"N\":\"wd_wd\"}]\u0000"

			$json_str2 = str_replace("\u0000", "", json_encode($decrypted2));

			$arr2 = json_decode(json_decode($json_str2), true);

			print_r($arr2);

			//aes加密方案1 mcrypt_encrypt 超过7.1舍弃了就，php7.1屏蔽错误还可以用

			$mingwen3 = "你好";

			$key3 = 'OKLU520XJB09906H';

			$iv3 = $key3;

			$encrypted3 = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key3, $mingwen3, MCRYPT_MODE_CBC, $iv3);

			$miwen3 = base64_encode($encrypted3);

			echo $miwen3;

			//代替方案  openssl_encrypt 方式更通用

			$key4 = "OKLU520XJB09906H";

			$iv4    = $key4;

			$mingwen4 = "你好";

			if (strlen($mingwen4) % 16) {

			    $mingwen4 = str_pad($mingwen4, strlen($mingwen4) + 16 - strlen($mingwen4) % 16, "\0");

			}

			$encrypted4 =  openssl_encrypt($mingwen4, 'AES-128-CBC', $key4, OPENSSL_NO_PADDING, $iv4);

			$miwen4 = base64_encode($encrypted4);

			echo $miwen4;

			//aes解密方案2

			$miwen33 = "fyy6UkIa/PXyXxR5vm316w=="; //你好

			$key33 = 'OKLU520XJB09906H';

			$iv33 = $key33;

			$plain_str33 = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key33, base64_decode($miwen33), MCRYPT_MODE_CBC, $iv33);

			$plain_str33 = str_replace(array("\r\n", "\r", "\n", "\0"), "", $plain_str33);

			echo json_encode($plain_str33);

			$miwen44 = "fyy6UkIa/PXyXxR5vm316w=="; //你好

			$key44 = "OKLU520XJB09906H";

			$iv44 = $key44;

			//OpenSSL 解密  或者OPENSSL_NO_PADDING

			$plain_str44 = openssl_decrypt(base64_decode($miwen44), "aes-128-cbc", $key44, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv44);

			$plain_str44 = str_replace(array("\r\n", "\r", "\n", "\0"), "", $plain_str44);

			echo json_encode($plain_str44);
