OpenSSL加密与BouncyCastle解密不兼容？

I am sending a encrypted mail using OpenSSL in an android app. While sending the mail this is the relevant native code -

我在Android应用程序中使用OpenSSL发送加密邮件。发送邮件时，这是相关的本机代码 -

cipher = EVP_rc2_40_cbc();
int flags = PKCS7_STREAM;
PKCS7* p7 = PKCS7_encrypt(certs, bio, cipher, flags);
int r = SMIME_write_PKCS7(out, p7, bio, flags);

The mail is successfully sent to the server and I get a sent mail notification.

邮件已成功发送到服务器，我收到已发送邮件通知。

Now when I am trying to open the mail using the another android app which has bouncycastle I am unable to open it. It says "Unable to decrypt message."

现在，当我尝试使用另一个具有bouncycastle的Android应用程序打开邮件时，我无法打开它。它说“无法解密消息”。

Also I tried openning the app using the webmail - interface on desktop. Here also I was unable to open the mail.

此外，我尝试使用桌面上的webmail接口打开应用程序。在这里我也无法打开邮件。

Any Idea what could be the problem?

任何想法可能是什么问题？

I tried using a different cipher also ( 3des ). But that too did not work.

我也试过使用不同的密码（3des）。但这也行不通。

Update -> If I change my encryption code to bouncy castle then everything works fine. I am able to decrypt in both android app and web-browser. So is there a possibilty that this might be a OpenSSL Issue?

更新 - >如果我将加密代码更改为bouncy castle，那么一切正常。我能够在Android应用程序和Web浏览器中解密。那么这可能是一个OpenSSL问题吗？

Update 2 -> I tried decrypting the encrypted text using openssl command prompt and it worked. So I guess it is surely some compatibilty problem? But is this a problem with bouncycastle or with openssl ?

更新2 - >我尝试使用openssl命令提示解密加密文本，它工作正常。所以我猜这肯定是一些兼容性的问题？但这是bouncycastle还是openssl的问题？

It turns out I was missing a flag.

事实证明我错过了一面旗帜。

int flags = PKCS7_STREAM | PKCS7_BINARY;

This did the charm.

这样做的魅力。
