Uploading using SFTP
We encourage you to use SFTP (or FTPS) if possible since it is more secure than plain FTP. This article is about uploading using SFTP connections. For a more in-depth look at the SFTP protocol, you may find this article helpful.
Passwords versus Public Keys
To use a public key instead of a password requires your computer and Host to be suitably set up. By using a public key, the security of the connection is increased since the encryption method is agreed before the handshake. (Suffice to say, if you don't understand this, using a public key is not for you!).
For some background information on public keys, you may be interested in this article.
The Connection Process
Authorizing the Connection
Whenever Sandvox connects to a host by SFTP, it checks the host key (also called fingerprint) of the server.
If the host key has changed since the last time Sandvox connected, you will be alerted. This is because if the host key of a server changes, it is possible that the server has been compromised, placing your personal data at risk.
It is also possible that the file which Sandvox checks host keys against is corrupt. If so, you will be alerted and asked to contact Karelia Support.
If your private key file is protected by a passphrase, Sandvox will prompt you for the passphrase as needed.
