“Secure Shell or SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices. Used primarily on Linux and Unix based systems to access shell accounts, SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notably passwords, in plaintext, leaving them open for interception. The encryption used by SSH provides confidentiality and integrity of data over an insecure network, such as the Internet.”
What SSH’ing your device will allow, is customizing almost every part of your device.
A working Wi-Fi connection will be required for this guide.
Go ahead and open Cydia on your device. When Cydia has started, tap Search.
