This particularly affects the use of encryption keys in OpenSSH, OpenVPN

This is a simple “encryption” tool to work with common simple encryption algorithms (ROT13, Caesar, Vigenère, …) Gcipher does not provide any strong encryption and should not be used to encrypt any private data.Gcipher can run as either a GUI, a command-line application, or a network proxy.
