Jul 10, 2011 · SSL (TLS) establishes a secured, bidirectional tunnel for arbitrary binary data between two hosts. HTTP is a protocol for sending requests and receiving answers, each request and answer consisting of detailed headers and (possibly) some content.

The first thing to be sent over the connection is a SSL/TLS handshake, and all application data will be sent encrypted. HTTPS will always be Implicit SSL. By contrast, Explicit TLS means that SSL/TLS will be negotiated explicitly as part of the underlying application protocol. This is common e.g. in the case of application protocols such as ...

Oct 7, 2018 · While all network models are imperfect, this question can only be answered by looking at what SSL (TLS really) does. (1) On top of a reliable network stream (TCP at OSI layer 4) it provides an encrypted bidirectional stream and (almost always) guarantees the identity of the server and (optionally) the client.

Sep 28, 2012 · which version of SSL/TLS it is running, what ciphersuites it wants to use, and; what compression methods it wants to use. The server identifies the highest SSL/TLS version supported by both it and the client, picks a ciphersuite from one of the client's options (if it supports one), and optionally picks a compression method.

Dec 17, 2024 · While analyzing the handshake process in TLS 1.3 and comparing it to TLS 1.2, I began to wonder if the simplified handshake structure in TLS 1.3 introduces new vulnerabilities. This concern is particularly relevant in scenarios involving SSL/TLS flood attacks. Assuming both TLS 1.2 and TLS 1.3 use ECDHE:

SSL/TLS supports renegotiation feature to allow the Client and Server to change the Cipher negotiated during the first handshake which provided the flexibility to change the Authentication Method as well as Cipher for Data Transfer.

EDIT: See here: How does SSL/TLS work? Or Here Self-signed cert - how it works I don't undertand, when I signed the certificated by CA the protocol is this: client send Hello to Server--- Server send hello and certificate to Client--- Client verify certificate with a CA and send confirmation to Server--- Finally Server send confirmation signed ...

According to nginx documentation the ssl_trusted_certificate parameter contains trusted CA certificates used to verify client certificates and OCSP responses if ssl_stapling is enabled and the list of these certificates will not be sent to clients.

The attacker then proceeds to do a normal SSL/TLS handshake with the server. The attacker injects a command X to the server S (the kind of command that requires user authentication). Somehow , a renegotiation is triggered: this is a new handshake, complete with messages, performed within the already established A->S SSL connection.

Nov 18, 2016 · So the simple answer to your question, "determine the version of SSL/TLS", is "TLS 1.2". Now, I've seen varying reports as to whether Wireshark can properly parse TDS packets with encoded TLS. I think that the answer is what you started with - it will tell you TLS is there, but won't parse the details as it would with a native TLS session.
