Need a specialist to set up secure data exchange via SSH
I am looking for a professional to implement secure file exchange between two machines. The task includes:
Creating and configuring cryptographic infrastructure (key pairs);
Encrypting data using the public key;
Transferring encrypted files via SSH;
Decrypting received data on the recipient's side.
I am expecting clear instructions or an automated script that performs the above actions. Preferably — with a brief explanation of how it works

Good day! I can write a script that encrypts files and transfers files over an encrypted channel via ssh (scp) or rsync over ssh + pgp. I will also include clear instructions in the scripts explaining how I did it and how to use it. Write to me, I will be happy to cooperate!

The ssh protocol provides encryption of all data by default, sftp which uses ssh transmits data encrypted
