问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 6 years ago . 2nd update : Now the server says: "Ready to start TLS", how to modify my code to perform this TLS negotiation? I am trying to use boost asio to send an email from one account to another, but failing. #include <istream> #include <ostream> #include <string> #include <boost/asio.hpp>

openssl to negotiate SSL encryption for STARTTLS

北慕城南 提交于 2019-12-18 12:29:14
问题 I'm using openssl to connect to an SMTP server normally (without encryption), send a STARTTLS command, negotiate the SSL encryption, and then interact with the encrypted session. This is the command I'm using (through telnet): openssl s_client -starttls smtp -crlf -connect 1.2.3.4:25 How can I ensure that TLS handshake was successful? This is the sequence of commands used so far: << 220 example.com ESMTP ready >> EHLO localhost << 250-smtp.mail.yahoo.com << 250-PIPELINING << 250-AUTH PLAIN

Java Netty Unknown SSL content type error

梦想与她 提交于 2019-12-08 15:43:01
I'm trying to write a HTTP client using Netty 5.0.0.Alpha2 to connect to a proprietary server. I can only describe the connection as being similar to Websockets but not. The server utilizes StartTLS which is expected to be initialized by the client after the server responds with 200 and Content Type and if you don't, the server disconnects you. Once the connection is secure, the server will keep the connection alive indefinitely while responding to client commands. Anyways, below is my SSLDump log and regarding the line "Unknown SSL content type 1", this happens once I try to send my first

Using StartTLS with LDAP from System.DirectoryServices

前提是你 提交于 2019-12-04 14:38:48
问题 I'm trying to connect to an LDAP server which requires StartTLS, but having no luck - whenever I use either the SessionOptions.StartTransportLayerSecurity(..) or set SessionOptions.SecureSocketLayer to true, I get exceptions. Here's the code I'm using: using (var connection = new LdapConnection(new LdapDirectoryIdentifier(config.LdapServer, config.Port, false, false))) { connection.SessionOptions.ProtocolVersion = 3; connection.Credential = new NetworkCredential(config.BindDN, config

tls: oversized record received with length XXXXX

纵然是瞬间 提交于 2019-12-04 14:13:17
I use the built-in standard SSL socket client library (net + crypto/tls) like this: conn, err := net.Dial("tcp", "exploit.im:5222") //... config := tls.Config{InsecureSkipVerify: true} tls_conn := tls.Client(conn, &config) fmt.Println(tls_conn.Handshake()) And am getting the message: conn, err := net.Dial("tcp", "exploit.im:5222") I managed to find out it is somehow related to the default maximum packet size (16384 + 2048 set in common.go:31). Is there any standard work around (without patching this value & rebuilding the lib)? You get this kind of messages if you try to do a SSL handshake

Using tls-extra for simple smtp

青春壹個敷衍的年華 提交于 2019-12-03 12:37:19
I am trying to write a simple script to send a mail via my gmail account. But I am a beginner so it is not that simple. I tryed google but exept for hackage, there is no help or examples at all. The problem is that I did not find the way to use tls-extra(or tls) to initiate the STARTTLS exchange. Ok, here is the code: import Network import Network.TLS.Extra import System.IO import Text.Printf server = "smtp.gmail.com" port = 25 --that has to chage, I think forever a = a >> forever a main = test1 write :: Handle -> String -> IO () write h s = do hPrintf h "%s\r\n" s printf "> %s\n" s listen ::
