大佬们,请问这段java代码如何在webman里实现。。

问题描述

使用php获取pubkey.bin以后,获取到了二进制文件,但是始终无法用X509加载

这是php代码

$file = 'pubkey.bin';
$handle = fopen($file, "rb");
        if ($handle) {
            $contents = fread($handle, filesize($file));
            fclose($handle);
        } else {
            return "无法打开文件";
        }

        $string = base64_encode(serialize($contents));

        $beginpem = "-----BEGIN CERTIFICATE-----\r\n";
        $endpem = "-----END CERTIFICATE-----";

        $string = $beginpem.$string.$endpem;

        var_dump($string);

        $certificate = openssl_x509_read($string);  
        if ($certificate === false) {  
            // 解析错误处理  
            return '无法解析';
        }  

        return 'ok';

下面是java代码

String text = "pub"; 
text += "@@@" + new Date().getTime(); 
FileInputStream fis = new FileInputStream("pubkey.bin"); 

byte[] b = new byte[fis.available()];
fis.read(b);
fis.close();

X509EncodedKeySpec spec = new X509EncodedKeySpec(b);
KeyFactory factory = KeyFactory.getInstance("RSA");
PublicKey pubKey = factory.generatePublic(spec);
Cipher c = Cipher.getInstance("RSA/ECB/PKCS1Padding");
c.init(Cipher.ENCRYPT_MODE, pubKey);
byte encryptOut[] = c.doFinal(text.getBytes());
String accessKey = new String(Base64.encodeBase64(encryptOut));

<?php
$text = "pub";
$text .= "@@@" . time();

$pubKey = file_get_contents('pubkey.bin');

$pubKey = openssl_pkey_get_public($pubKey);
$encryptOut = '';

openssl_public_encrypt($text, $encryptOut, $pubKey, OPENSSL_PKCS1_PADDING);

$accessKey = base64_encode($encryptOut);
?>

    可能是因为这个bin文件的原因,读取出来后,使用openssl_pkey_get_public无法获取。。

    // 读取二进制文件
    $binaryData = file_get_contents('binaryfile.bin');
    
    // 转换二进制数据为十六进制
    $hexData = bin2hex($binaryData);
    
    // 将十六进制数据转换为 PEM 格式
    $pemKey = "-----BEGIN PUBLIC KEY-----\n" .
               chunk_split($hexData, 64, "\n") .
               "-----END PUBLIC KEY-----\n";
    
    // 获取公钥
    $publicKey = openssl_pkey_get_public($pemKey);

gpt翻译如下:


$text = "pub";
$text .= "@@@" . round(microtime(true) * 1000); // Equivalent of new Date().getTime() in Java

$fileContent = file_get_contents("pubkey.bin");
$key = openssl_get_publickey($fileContent);

$cipherText = '';
openssl_public_encrypt($text, $cipherText, $key, OPENSSL_PKCS1_PADDING);

$accessKey = base64_encode($cipherText);
