https://svn.boost.org/trac10/ticket/10828 <p> I'm writing a test unit that uses the boost asio ssl. </p> <p> I'm using Boost 1.54 on Ubuntu 14.04 64 bit. </p> <p> I plan to make the test self-sufficient and not rely on files to specify the private key, so I want to hard encode the key and its password in the test itself (they are just test key and password). </p> <p> The code is below. For now it does nothing but I'm just trying to make the password callback work when the private key is specified: </p> <hr /> <p> std::string password_callback( </p> <blockquote> <p> std::size_t max_length, boost::asio::ssl::context::password_purpose purpose) </p> </blockquote> <p> { </p> <blockquote> <p> return "test"; </p> </blockquote> <p> } </p> <p> TEST(<a class="missing wiki">StreamReader</a>, sslStream) { </p> <blockquote> <p> std::string certificate = "-----BEGIN CERTIFICATE-----\n\ </p> </blockquote> <p> MIIFJjCCAw4CCQDQjrFrRcdRkjANBgkqhkiG9w0BAQsFADBVMQswCQYDVQQGEwJT\n\ BLABLABLABLA"; </p> <blockquote> <p> std::string key = "-----BEGIN RSA PRIVATE KEY-----\n\ </p> </blockquote> <p> Proc-Type: 4,ENCRYPTED\n\ DEK-Info: DES-EDE3-CBC,06622C22CAB27AC2\n\ \n\ JMudxXy4ZxB733xh7QO4elsVCTzJZuWl9Go4ZMuWx0DZb2fYHqXynKZSf7UactSw\n\ vhKJnLPZaa5U+xOr9cdpSd3SwtQyNu6yaVQH3af2ILRwUsw9mQmI8yqIIF1Y6AgV\n\ BLABLABLABLA"; </p> <blockquote> <p> boost::asio::io_service io_service; boost::asio::ssl::context ctx(boost::asio::ssl::context::tlsv12); ctx.set_password_callback(password_callback); ctx.use_certificate(boost::asio::const_buffer(certificate.c_str(), certificate.size()), boost::asio::ssl::context::pem); ctx.use_private_key(boost::asio::const_buffer(key.c_str(), key.size()), boost::asio::ssl::context::pem); ctx.set_verify_mode(boost::asio::ssl::verify_peer); </p> </blockquote> <p> } </p> <hr /> <p> When use_private_key is executed then the password callback is not called and I have to enter the password manually in the console.
