Secure File Transfer Protocol or sFTP is a way of transferring files using FTP where the data is encrypted.
There are two possible ways to transfer the data securely:
- FTP-TLS/SSL - This uses the standard port 21 and encrypts the FTP session in a TLS layer.
- SFTP -
This uses something called Secure Shell (SSH) and it works almost exactly
like the FTP-TLS method. Although the encryption is not handled by a
browser, it is handled by the SSH server in your web hosting account.
SSH is not supported by all packages and we recommend use of FTP-TLS/SSL which is offered to all.
