EC curves not working in Response Proxy

[Vincent Boidyo]

Hello Dennis,
I'm trying now concept with Server, Reponse-proxy and Client.
Bewlo the commands :-
Sever:- ./uftp -M 232.X.X.X -R 99999 -B 7355555 -p 9094 -t 10 (path)
Response Proxy:- ./uftpproxyd -r -t 10 -e sect163k1 -d -M 232.X.X.X -C (Clientfile_list) B 7355555 -p 9094
Client:- ./uftpd -B 7355555 -S (Serverfile_list) -R (Response-proxy IP) -p 9094 -d -D /tmp/dir1 -T /tmp/dir2
Server-->> Response-Proxy it works fine.
Response-Proxy to Client, it dosen't work.
Running cmd in Client:-
Say, Sent KEY_REQ to (Response-proxy IP):9094
Runing cmd in Response proxy:-
Recieved KEY_REQ from (Client IP)
error exporting public key

And as sugested for prime256v1 but still the same error.....

I've tried all EC curves: prime256v1, secp384r1, and secp521r1.
But still I get the same error message.
Not sure what is missing and where I'm making a mistake.
Please help me figure this out.
Thank you.

What OS and version are you running?

[Vincent Boidyo]

I'm using Mojave 10.14.4 version.

thank you.

I don't have a Mac handy so I can't reproduce the issue. You should still be able to use the proxy without encryption support. Remove the -e option from the proxy and see if you can get that working.

[Dennis Bush]

Did you compile with encryption support disabled? If so that would explain the error as there's no key to export. Currently, using a response proxy requires encryption to be enabled but not necessarily used.

Hello Denis,

How do I compile with encryption support disabled?
I'm not sure how to do it.

Please help me the steps

Thank you.

[Dennis Bush]

If you don't know how then you probably didn't disable encryption, which means it still doesn't explain the issue. Did you compile the code yourself or did you download executables from someplace?

[Vincent Boidyo]

I've generated an ssh-keygen and saved in default location. The Ecurve I got it from the website which was listed. I haven't compile any code.

how do I got from here, please help me.

Hello Dennis,

Please let me know if any addition informatrion required.

Cos, I'm stuck and awaiting for your response.

Thank you.

[Dennis Bush]

It sounds like you got the code precompiled from some external source which you didn't specify. Whoever compiled it may not have enabled encryption. If that's the case then you need to compile the code yourself, and you need to download the OpenSSL libraries which are needed for encryption.
