I did follow this tips https://rietta.com/blog/openssl-generating-rsa-key-from-command/

 

Perfect!

Did you chmod the private key to only match your user?

chmod 700 private.key

What is the purpose of your signing process? Authenticity( making sure the data is not tampered with and is from you ) or for no one else to see the content.

I did not chmod... should I?

The purpose is to make sure that the data is not tampered with and that it belongs to me.

Private keys should never ever leave the owning user's home directory. Ideally you should use a memory stick for your keys, and only copy the public key to your computer. Put the memory stick in a physical safe.

It is in the same home directory "I am using MAC OXS", let me say all 3 files (file_to_be_delivered; Public e private key) are in home directory

I have to encrypt it and send the public key & File to the finance Department. How can I do it?

Pardon my interrupting a trolling session in progress, but...

I am not sure I fully understand your question. And I am even less sure why are you asking it here. Allow me to explain:

While it may be possible to encrypt a message using a private key, it is not the accepted method for proving the message's authenticity. Normally you would generate a digital signature of the message in a separate file. You should check with your recipient what their exact requirements are. 

Filemaker cannot encrypt the data for you. If it turns out that's what they want you to do, you will need to use another tool (e.g. the Terminal). Filemaker can help automate such process via Applescript  - but the actual contents of the script have nothing to do with Filemaker and require a different expertise altogether.

Filemaker can generate a digital signature file - but you will need version 18 for this. Your profile says "11 Advanced".

Hopefully this helps to put things in some perspective.
