How to connect server by quickfix using private key

Question

Im connecting to server using FIX protocol 4.4. Previously i used username and password for authentication.

Below is my configuration file

[DEFAULT]
ConnectionType=initiator
HeartBtInt=30
ReconnectInterval=30
ResetOnLogout=Y
ResetOnDisconnect=Y
FileStorePath=/tmp/msgs/
FileLogPath=/tmp/msgs/log/
StartTime=00:00:
EndTime=00:00:00
UseDataDictionary=N
SocketConnectHost=193.~.~.~
SocketNodelay=Y
PersistMessages=N

[SESSION]
BeginString=FIX.4.4
SenderCompID=abcdefh
TargetCompID=abcdefh
SocketConnectPort=7000
SenderSubID=abcdefh
Password=abcdefh

Now have to connect without using SenderSubID & password, but using private key. The keys are given in a pem file. I am giving sample of the code below

Bag Attributes localKeyID: 12 23 34 45 56 AX SC DV FV FB 12 23 34 45 56 AX SC DV FV FB subject=/CN=abcdefgh issuer=/C=GB/ST=London/L=London/O=DB/OU=GM/CN=demo fix dev -----BEGIN CERTIFICATE----- abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890 -----END CERTIFICATE----- Bag Attributes: subject=/C=GB/ST=London/L=London/O=DB/OU=GM/CN=demo fix dev issuer=/C=GB/ST=London/L=London/O=DB/OU=GM/CN=demo fix dev -----BEGIN CERTIFICATE----- abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890 -----END CERTIFICATE----- Bag Attributes localKeyID: 12 23 34 45 56 AX SC DV FV FB 12 23 34 45 56 AX SC DV FV FB Key Attributes: -----BEGIN RSA PRIVATE KEY----- abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890 -----END RSA PRIVATE KEY-----

I don't know how to proceed or what to do with this PEM file
I am new to java and FIX protocol

If anyone can explain the solution with java code, that would be very helpful

thanks

Answer 1

in order to connect with a counterparty with a PEM key, you have to install and config a new software.

In our production environment, we use sTunnel (https://www.stunnel.org/index.html) , a free software for tunnel and encrypt messages over a SSL layer.

Please download this sotware and read the manual for the config settings.
