通过PHP生成crx文件失败,错误为:“;包无效:CRX“U签名”“U验证”“U初始化”“U失败”;
我正在使用PHP生成一个crx文件。当我尝试将crx安装到Chrome中时,出现了以下错误:通过PHP生成crx文件失败,错误为:“;包无效:CRX“U签名”“U验证”“U初始化”“U失败”;,php,google-chrome,google-chrome-extension,openssl,public-key-encryption,Php,Google Chrome,Google Chrome Extension,Openssl,Public Key Encryption,我正在使用PHP生成一个crx文件。当我尝试将crx安装到Chrome中时,出现了以下错误: Package is invalid: 'CRX_SIGNATURE_VERIFICATION_INITIALIZATION_FAILED' 这是我的密码: <?php //Include phpseclib files include('File/X509.php'); include('Crypt/RSA.php'); //RSA Handler $rsa = new Crypt_RSA(

我做错了什么?我猜这与密钥的格式和签名有关?我找到了答案!签名使用的是
CRYPT\u RSA\u签名\u PSS
,显然只适用于PKCS1
。因此,您需要添加以下行:
$rsa->setSignatureMode( CRYPT_RSA_SIGNATURE_PKCS1 );
在签名创建代码之前。因此,签名代码现在如下所示:
//Load the private key into the handler
$rsa->loadKey( $privKey );
//Sign the content (default is SHA1)
$rsa->setSignatureMode( CRYPT_RSA_SIGNATURE_PKCS1 ); /* <-- This is required */
$signature = $rsa->sign( $zipContents ) ;
//将私钥加载到处理程序中
$rsa->loadKey($privKey);
//对内容进行签名(默认值为SHA1)
$rsa->setSignatureMode(加密\u rsa\u签名\u PKCS1);/*符号($zipContents);
