SSH with ssl_openssl and Synapse?
« on: July 13, 2020, 06:04:16 pm »
Hi,

I'm trying to connect to a SSH server with ssl_openssl and Synapse - unfortunately with no luck until now.

P.S. Reading a https page with THTTPSend works, so I think OpenSSL works.

My system: Linux Mint Xfce 18.3 64 Bit.

Are there examples or small demos?

Thank you!

You are probably trying to connect with one of the legacy protocols that have been removed from openssl (and all serious others). Try a connection with at least tls 1.1 and nothing like ssl2/3/tls1.0.

I don't think openssl is enough. You'll need a libssh2.sll to do SSH (or cryptlib which isn't opensource).

You can begin here
https://forum.lazarus.freepascal.org/index.php/topic,28053.msg178389.html#msg178389

Wasn't there a wiki page with a ssh connect example somewhere?
Yes. Here https://wiki.freepascal.org/Synapse

They're completely distinct protocols. As others have said: look for the appropriate libraries. Or alternatively, investigate whether you could wrap a standard SSH client in your code.

ópenssl is capable of ssh on its own.

I'm sure you can provide us with an example in Lazarus to connect to a SSH server with just openssl, right  :D

Yess. I will do a write up. Takes 2-3 days.
