Encrypting Data Transmission

Encrypting Settings Data

All communication with Settings can use SSL encryption if you access the Settings page by changing "http://" to
"https://" in the browser address bar or click [Secure Connection] from the login window. Once you are logged in
using the HTTPS connection and wish to disable SSL encryption, click [Normal Connection] from the login window.

Encrypting FTP Transfer Data

You can encrypt passwords and files using SSL/TLS for secure FTP communication. First, open a shared folder's
settings and click [Edit]; under "LAN Protocol Support", select the "FTP" checkbox and click [OK]. Afterwords, enable
SSL security in the setup screen for your FTP client. The procedure depends on the FTP client software.

SSL Keys

SSL keys are used during setup screen operations and FTP communication. SSL (Secure Socket Layer) is a type of
encryption system called public key encryption. Generally, SSL is managed by the two files below.
server.crt (SSL Certificates)
The LinkStation sends the file to a computer, and the computer uses it to perform encryption. The LinkStation
receives the encrypted data and uses server.key (the private key) to decrypt the data.
In SSL, this key contains the server certificate, and depending on your computer environment, a check may be
performed to determine the trustworthiness of the certificate. The server certificate included in the LinkStation's
default settings was created by Buffalo, and in some cases, the security certificate warning message may appear in
your browser or another security software. Disregard this message and continue.
server.key (SSL Private Key)
This file is used as a pair with server.crt (server certificate). This is required for decrypting the data that was
encrypted by the server certificate, and this is normally not revealed.
Note: The passphrase for the private key must be removed before importing to the LinkStation.
