I can't help you much on the server side of the equation, but this excerpt from
an FTP client job will get you started:
01 //FTPS EXEC PGM=FTP,REGION=4M,
02 // PARM=('ENVAR("_CEE_ENVFILE_S=DD:STDENV")/10.1.1.1 5521 -e')
03 //STDENV DD *
04 GSK_PROTOCOL_TLSV1_2=ON
05 //* GSK_TRACE=0xFFFF
06 //* GSK_TRACE_FILE=/tmp/gsk.trc
07 //* The 2 stmts above can be temporarily uncommented for debugging
08 //SYSFTPD DD *,SYMBOLS=(JCLONLY)

02 _CEE_ENVFILE_S=DD:STDENV
- Allows you to specify LE overrides via a SYSIN DD rather than a VB dataset
0.1.1.1 5521
- Your server IP address & port
-e
Exit step with FTP return code instead of 0 (probably overridden)
05 & 06
GSK_TRACE...
Turns on GSK tracing for FTP client, writes trace records into /tmp/gsk.trc
file
Use gsktrace "gsk.trc > gsk.out" command to format into human readable.
Very helpful
13 You will have to have a public/private key known to the server, and a
public key or
CA cert shared with the client (if on the same system, then on the same
key ring is fin)
11 & 16 are also important
You'll need to use the manuals to understand most of the commands, but this
will get you started.
Some of these manuals may help:
SC14-7495-30 Cryptographic Services System Secure Sockets Layer Programming
SC27-3651-30 IP Configuration Reference
GC27-3652-30 IP Diagnosis Guide may be useful if you are getting GSK errors.
SA23-2292-30 Security Server RACF Command Language Reference contains the
syntax for the RACDCERT instructions.
