Publickey mode:
Selecting the Public key mode will bring up the Pairing mode options: Auto, Download, Upload .
Auto Camera will generate a key pair and auto pair public key with the SFTP
server.
Download Camera will generate a key pair and download the public key for the user to
upload it to the SFTP server. The supported formats are: ED25519 (default.
Elliptic curve signature scheme Edwards-curve Digital Signature Algorithm;
with faster key creation, encryption and decryption ), RSA ( Rivest–Shamir–
Adleman, with greater portability ), ECDSA ( Elliptic Curve Digital Signature
Algorithm ).
Upload Upload the private key here and upload the public key to the SFTP server.
A private key is a guarded secret and it can be stored on disk in an encrypted
form. A passphrase is used in order to decrypt it. It is a login password to the
SSH server, the passphrase is only used to decrypt the private key on the
local system. The passphrase is not transmitted over the network.
When using SFTP, you can authenticate using a public/private SSH key pair instead of a
password. If key authentication is not enabled, you need to specify a password instead. The
administrator of the SFTP server will need to manually add the corresponding public key to the
SFTP server.
The key benefit of a key-based authentication is that instead of a using a password, you are less
vulnerable to brute-force attacks and you do not expose valid credentials, if the server has been
compromised.
