uses an algorithm that allows you to collapse the text you want to save time transferring and then send the message encrypted so that the recipient receives the document with the highest possible security.
Also, when using PGP the message is digitally signed. Therefore, the receiver trusts its authenticity due to the security process that the message has passed.
If you want to know how to install and use PGP on a Linux computer you should continue reading this article. We will show you the steps you need to do for this task.
Why should you install PGP on Linux? Advantages of doing it
when you use PGP in linux you will be able encrypt all messages you send through your email, which will strengthen security because no one, except the recipient, will be able to decrypt the email. Also, You will have the possibility to use two types of keys, one public and one private. The first being the one that you must share with the sender so that he can decrypt the message.
This benefits the security process because the recipient receives the email with a high level of certainty, since it is digitally signed by the sender. Public keys are visible to everyoneso it is not necessary to hide this information, since it is only part of the process of decoding the message. This allows trust and transparency in the .
Every time you encrypt a folder you use a session key, which is used only once fortifying the encryption system.
Another point you should keep in minda is that when encrypting the messages through the PGP protocol the size of the mail or the files are compressed. This makes it possible to save time, not use so much mobile data (if that’s what you do on the street with a phone) and not take up too much space on the storage disk.
Accessing a PGP protocol program for Linux is not difficult, so any user can download it for free an encryption software. And if you prefer, you can contract payment tools or work with online platforms.
Finally, if you use the Ubuntu distro you will not need to do any steps, since GnuPG is the program that comes installed with an operating system. This means that you will save time and that you only need to activate this tool to start using it.
Are PGP and GPG compatible on Linux or is it better to choose one of them?
So much Pretty Good Privacy (PGP) as GNU Privacy Guard (GPG) are two tools that are used for the encryption of emails and the encryption and decoding of data through online functions that allow you to maintain the security of the sent items at all times.
For this reason, no need to install PGP and GPG on the same computersince their results will be similar. gpg is a derivative of the project PGP and is in charge of the Guard of GNU, which generates the keys for the management of encryption through NIST Advanced Encryption Standard.
Although there are other more complex technical differences, the one we mentioned above is the most important that exists with PGP, since this protocol uses encryption International Data Encryption Algorithm.
Therefore, it can be concluded that when the level of encryption is not bulky you should use GPGbut if you need to encrypt the hard drive of a large database of including emails it is recommended to use PGP.
Learn step by step how to install PGP on a Linux computer
To install PGP on a computer with a Linux operating system you must follow this step by step:
Install the software on your computer
The first thing you should do is open the terminal and type sudo apt-get install gnupg2 GPA to know the dependencies to work correctly with gnuPG with Gnu Wizard . Once you have completed this step, you must confirm the space by pressing the key “Y”.
Create the encryption keys
At this time you will have to use the protocol RSA of 4096 bits to increase the level of security (if you prefer you can use shorter ones, but it is not recommended). So you will have to enter the command gpg –gen-key and then 1, when the program asks what type of security is desired. Next, you will have to choose the length of the key, which is given from 4096 bit. In addition, you will have to choose the duration time of the key, you can do this by typing key does not expire. When you have finished you will have to enter “Y” and then Enter.
Enter an ID to be recognized by the sender
In this step you will create one so that people who receive the message can identify the key. In this case you will have to choose the option EITHER that the system offers you and then enter a that only you know.
Do not forget that the encryption system is asymmetric. This means that the sender uses the recipient’s public key to encrypt the message, then the recipient uses their private key to decrypt the mail or file.
Access the Key Manager
You are now in a position to be able to safely use the keys. For this you will have to open the Key Manager from the program by typing the command sudo gpa. Next, you will have to click on keys and then in Export Keys… in order to access the button Save.
encrypt the message
What you should do now is enter the option Clipboardin the tab windows, and select the recipient who will have the mail. Once you have done this you must click on the button To accept for the message.
