A public key is used to encrypt a file and verify a signature.
A private key is used by the owner to decrypt and to add a digital signature to files.
A key ring (otherwise known as a key store) is a small binary file which can store one or more OpenPGP keys. Public keys are stored in Public Key Rings and private keys are stored in Secret Key Rings.
You can manage OpenPGP keys thru the GoAnywhere key manager. You can access the PGP key manager thru the Tools drop down menu.
You will need your Trading partner’s public key to encrypt a file.
Your trading partner will use their private key to decrypt that file.
