To connect to our z/OS mainframe FTP server using FTPS, I was given certificate files in .crt format. It seems that REBEX wants to use .pfx certificate file format. Is there any way to get REBEX to use the .crt files?

And/or do you have any information about connecting to a z/OS mainframe FTP server?

Which certificate does the .crt file actually contain? Is it the server certificate (and you just want to validate whether the server actually presents this one to the client), or is it a client certificate you would like to use to authenticate yourself (the client) to the server?

The newly added CertificateChain.LoadDer method might handle those .crt files.
