Sun Java KeyManagerFactory和空密码 [英] Sun Java KeyManagerFactory and null passwords

问题描述

我们在Sun JRE 1.6中遇到了KeyManagerFactory的问题。我们使用类似于以下内容的代码上传和使用p12格式的证书：

We are having a problem with the KeyManagerFactory in the Sun JRE 1.6. We are using code similar to the following to upload and use a certificate in p12 format:

KeyStore keyStore = KeyStore.getInstance(PKCS12);
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(SUN_X509);

InputStream certificateFile = getSSLCertificate();
String certificatePassword = getSSLCertificatePassword();
keyStore.load(certificateFile, certificatePassword);
keyManagerFactory.init(keyStore, certificatePassword);

当证书密码存在时，此代码可正常工作。但是当证书密码为空（因此证书不受密码保护）时，我们会从keyManagerFactory.init行得到除零错误。

This code works correctly when the certificate password exists. But when the certificate password is null (so the certificate is not protected by a password) we get a divide by zero error from the keyManagerFactory.init line.

有谁知道为什么会这样？没有密码就不能使用证书吗？
谢谢

Does anyone know why this is happening? Is it not possible to use a certificate without a password? Thanks
