This is the first time I ever do a discussion so I apologies if I don't make sense,
I'm trying to pwn a HTB machine (ARCHETYPE) and so far, I've been stuck with this problem for days, when using mssqlclient.py with the correct syntax and pressing enter, it shows the { [*] Encryption required, switching to TLS } and then goes back to normal terminal which doesn't make any sense.

I've changed the configuration in the tds.py file which was about the TLS configuration, here's what it looks like rn:

 if resp['Encryption'] == TDS_ENCRYPT_REQ or resp['Encryption'] == TDS_ENCRYPT_OFF:
            LOG.info("Encryption required, switching to TLS")

            # Switching to TLS now
            ctx = SSL.Context(SSL.TLSv1_METHO)
            ctx = SSL.Context(SSL.TLSv1_2_METHOD)
            ctx.set_cipher_list('RC4, AES256')
            tls = SSL.Connection(ctx,None)
            tls.set_connect_state()
            while True:
                try:
                    tls.do_handshake()
                except SSL.WantReadError:
                    data = tls.bio_read(4096)
                    self.sendTDS(TDS_PRE_LOGIN, data,0)
                    tds = self.recvTDS()
                    tls.bio_write(tds['Data'])
                else:
                    break

            # SSL and TLS limitation: Secure Socket Layer (SSL) and its replacement,
            # Transport Layer Security(TLS), limit data fragments to 16k in size.
            self.packetSize = 16*1024-1
            self.tlsSocket = tls

Looking at videos and other peoples discussions never talk about this problem, could this be a problem in my device or something in Impacket? I didn't want to skip this pen testing method because I don't want to do things without knowing whats going on so yeah.

one final thing to mention is that I tried entering the password after it connects:

Tell me if there's anything I missed.

I also get this all the time using Impacket main v0.12.0.dev1+20231114.165227.4b56c18a. If I switch to the Impacket version that comes by default in Kali 2023.4, v0.11.0, this works.

Hi,
linking this issue with #1356, to take into account when analyzing it. In the context of that PR the SSL connection set up has been changed.
however that code is the same both in v0.11 and in current master

Hey, Sorry for replying late, I haven't done any training ever since I made this discussion.
I actually used both v11 and v12, but I had the same response, I was going to show that I get the same response using the pre built version, but when I did, it actually worked, I'm losing my mind, I literally used both version to which never worked and now after all this time, it finally worked when I wanted to proof something.

Thank you again for helping, I actually bamboozled that it worked rn.
