Won't be able to paste the entire source code since the SIP application uses SipXces stack. SipStack has been built with open ssl which calls
SSL_connect as shown below 领导为SIP应用程序使用SipXces开发栈,不能粘贴整个源代码
。SipStack是用开放的ssl构建的,它可以调用SSL_connect如下所示

void OsSSLConnectionSocket::SSLInitSocket(int socket, long timeoutInSecs)

{

if (mIsConnected)

{

int err = -1;

// TODO: eventually this should allow for other SSL contexts...

mSSL = OsSharedSSL::get()->getServerConnection();

if (mSSL && (socketDescriptor > OS_INVALID_SOCKET_DESCRIPTOR))

{

SSL_set_fd (mSSL, socketDescriptor);

err = SSL_connect(mSSL);

Any pointers that you think I could verify from my end would be helpful.

 

!aNULL after (only) RSA is a no-op. !aNULL(仅在RSA之后)是空操作。

1. Make sure the application *runs* with your modified DLL(s). On Unix the equivalent is explicit, but IME most Windows versions
formerly tried the executable's directory first and then PATH but recent Windows security patches apparently changed this.

2. The default is only the default. If the application calls SSL_[CTX_]set_cipher_list that overrides. Unless you have a
reason to make this change across your entire system (or network) it's usually better for each application to configure
its own cipherlists than have 3 or 5 or 20 different OpenSSLs.

1.确保应用程序“ *”运行带有修改后的DLL。 在Unix上,等效项是明确的,但大多数Windows版本是IME 以前先尝试了可执行文件的目录,然后尝试了PATH
但是最近的Windows安全修补程序显然改变了这一情况。

2.默认值仅是默认值。如果应用程序调用覆盖的SSL_ [CTX_] set_cipher_list。除非你有一个
在整个系统上进行此更改的原因(或网络),通常每个应用程序最好都要配置拥有3或5或20个不同的OpenSSL的密码列表。

回复

I could not find application explicitly calling SSL_set_cipher_list() anywhere and it seemed to be using new libraries.
However as per your suggestion I am now setting the cipher list in the application before SSL_connect and it sends the desired ciphers.我找不到明确调用SSL_set_cipher_list()的应用程序任何地方,似乎都在使用新的库。 但是,根据您的建议,我现在将在SSL_connect之前设置密码列表,这样应用程序发送了所需的密码。
