大佬們，請(qǐng)問這段java代碼如何在webman里實(shí)現(xiàn)。。

問題描述

使用php獲取pubkey.bin以后，獲取到了二進(jìn)制文件，但是始終無法用X509加載

這是php代碼

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

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

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

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

        var_dump($string);

        $certificate = openssl_x509_read($string);  
        if ($certificate === false) {  
            // 解析錯(cuò)誤處理  
            return '無法解析';
        }  

        return 'ok';

下面是java代碼

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?yàn)檫@個(gè)bin文件的原因，讀取出來后，使用openssl_pkey_get_public無法獲取。。

// 讀取二進(jìn)制文件
$binaryData = file_get_contents('binaryfile.bin');

// 轉(zhuǎn)換二進(jìn)制數(shù)據(jù)為十六進(jìn)制
$hexData = bin2hex($binaryData);

// 將十六進(jìn)制數(shù)據(jù)轉(zhuǎn)換為 PEM 格式
$pemKey = "-----BEGIN PUBLIC KEY-----\n" .
           chunk_split($hexData, 64, "\n") .
           "-----END PUBLIC KEY-----\n";

// 獲取公鑰
$publicKey = openssl_pkey_get_public($pemKey);

gpt翻譯如下：


$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);
