If you wish to alter from Windows to GNU/Linux you can still carry that same key and a similar interface for your working.
Like we have mentioned above, Gpg4usb is “cross-platform”. You can abolish it with the master key and create your own subkey. Subkeys are crucial as they can be abolished to decrease the damage from a key that has already been compromised. The master key that will be offered to you will be used for signing other keys, abolishing subkeys, and also formulating new subkeys. Gpg4usb formulates RSA keys along with an encryption subkeys as well as a master key. In these cases you will not be owning the keys so you cannot be completely sure that they are not decrypting or encrypting texts that are meant for viewing by you only. You will need to keep in mind to avoid using online PGP methods like iGolder. This can be unsafe as, for instance, Kleopatra does not generate subkeys. This implies that they are not up to the date with the new version of GnuPG to cater to the latest standards of PGP. Others like Kleopatra, PGP4Win, and GPA use the depreciated versions of the GnuPG. Keep a note that not all the versions of PGP are formulated equally, there are some PGP programs that employ an unsafe or insecure version of PGP that have the chance of compromising the encrypted text. The OS that is used in this article will be Linux Mint, but the UI will remain similar across GNU/Linux distros and the versions of Windows. Like most of the PGP methods, it utilizes GnuPG as the backend. It offers a very lucrative user interface, portability so that it can be operated from multiple devices, and is of course open source. Gpg4usb is a PGP tool that can be operated on a USB drive and function on both GNU/Linux and Windows with the planned support of OS X.
