使用 PKCS12 向 IOS 发送电子邮件

Question

我有一个问题，我尝试使用加密 FKCS12 发送消息并签名，我正在使用 BouncyCastle 使用证书 (.cer) 文件加密消息，并使用 .pb12 文件对其进行签名，问题是这样的：

一些设备如black berry, android, outlook at windows,甚至Mac OSX都可以打开邮件，但是当他们尝试用IOS（iPhone 4）打开邮件时看不到内容，只能看到一条消息告诉“电子邮件已加密，要查看它，您需要安装包含其身份加密的身份”。

我认为发送电子邮件的Java进程是可以的。

¿有什么想法吗？

顺便说一句，这是代码：

MailcapCommandMap mailcap = (MailcapCommandMap)CommandMap
                .getDefaultCommandMap();

        mailcap
                .addMailcap("application/pkcs7-signature;; x-java-content-handler=org.bouncycastle.mail.smime.handlers.pkcs7_signature");
        mailcap
                .addMailcap("application/pkcs7-mime;; x-java-content-handler=org.bouncycastle.mail.smime.handlers.pkcs7_mime");
        mailcap
                .addMailcap("application/x-pkcs7-signature;; x-java-content-handler=org.bouncycastle.mail.smime.handlers.x_pkcs7_signature");
        mailcap
                .addMailcap("application/x-pkcs7-mime;; x-java-content-handler=org.bouncycastle.mail.smime.handlers.x_pkcs7_mime");
        mailcap
                .addMailcap("multipart/signed;; x-java-content-handler=org.bouncycastle.mail.smime.handlers.multipart_signed");

        CommandMap.setDefaultCommandMap(mailcap);

Answer 1

将输出加密器更改为 AES256_CBC 对我有用。

MimeBodyPart mp = gen.generate(msg, SMIMEEnvelopedGenerator.AES256_CBC, "BC");
