PHP AES加密JAVA到PHP-openssl_加密
我正在使用PHP中可用的openssl_加密函数来获得与下面的java代码生成的结果类似的结果 但情况完全不同。请帮帮我 JAVA代码PHP AES加密JAVA到PHP-openssl_加密,php,encryption,php-openssl,Php,Encryption,Php Openssl,我正在使用PHP中可用的openssl_加密函数来获得与下面的java代码生成的结果类似的结果 但情况完全不同。请帮帮我 JAVA代码 package com.atom.echallan.security.util; import javax.crypto.Cipher; import javax.crypto.SecretKey; import javax.crypto.SecretKeyFactory; import javax.crypto.spec.IvParameterSpec; i

我不知道为什么会这样。
字符串的长度相同,但结果不同。
如何获得与java相似的结果?我已经用下面的代码解决了您的代码,希望这能对您有所帮助
public function encrypt($data, $key = "4A8A53E16C9C34EA5E77EF9FF7B2FD04", $method = "AES-256-CBC") {
$salt="178";
//Converting Array to bytes
$iv = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15];
$chars = array_map("chr", $iv);
$IVbytes = join($chars);
$salt1 = mb_convert_encoding($salt, "UTF-8"); //Encoding to UTF-8
$key1 = mb_convert_encoding($key, "UTF-8"); //Encoding to UTF-8
//SecretKeyFactory Instance of PBKDF2WithHmacSHA1 Java Equivalent
$hash = openssl_pbkdf2($key1,$salt1,'256','65536', 'sha1');
$encrypted = openssl_encrypt($data, $method, $hash, OPENSSL_RAW_DATA, $IVbytes);
return bin2hex($encrypted);
}
1.确保生成的密钥等于2。您有不同的结果编码(十六进制与base64)。同样,您正在使用differet IV(在这两种情况下,IV都是以不安全的方式使用的),您能告诉我在php情况下,我应该为IV使用什么代码来匹配结果吗?ThanksIV需要是相同的,它通常是沿着CipherDemie java案例传递的随机数组,它是{1,2,3…}我不知道我应该用PHP写什么。它应该是16个字节,应该是一个字符串,Java它是一个数组。。。如何在PHP中实现同样的功能?您能帮我编写代码吗?感谢您的帮助..请注意解决方案不加密安全。使用static IV并重用相同的密钥(具有静态盐)可能不会产生完全安全的解决方案
