In essence, it means to jumble up all of your messages into a complex code that attackers cannot decipher. So why use it then? Because the other options all have their faults as well. Certificates also tend to cost money, which is another downside.

Instead, it takes messages that have certain specifications, then swaps them out for a link to a Microsoft server. The recipient gets sent the link, which sends them to the server where they can view the message. Another issue with each of these types of encryption is that they occur in the Microsoft environment.

This brings us back to PGP encryption. Although it does take some effort to configure in Outlook, PGP comes with many advantages. It also operates on a decentralized model that gives its users a range of choices when it comes to how their information will be encrypted and how they want to trust other users.

This all depends on your threat level. If you have more extreme privacy concerns, or deal with extremely sensitive and valuable information, it may be best to use Gnu Privacy Guard GPG with an email client like Thunderbird running through Enigmail instead. The first step for installing it is to download Gpg4win. This is an open-source package of encryption tools for Windows. It includes the Gnu Privacy Guard, which is the main encryption program, as well as some certificate managers, plugins and a user manual.

All of these come for free in the download package.

You will be brought to another popup that asks you to select your language.Perhaps for a little paranoia or for being diligent with the privacy of our communications, we want that some messages we send can only be read by whom we want to be read, for that we use encryption.

What is encryption? It is merely to take a readable message and turn it into something unreadable for anyone, except for the indicated recipient if he uses the appropriate tools. One of the most popular methods to encrypt messages in our era is to use PGP technology Pretty Good Privacywhich is a cryptography system quite widespread on the Internet. In this article, we will deal with the installation of software for its use although there are online applications that allow us to do this without installing anythingcreate and import keys and encrypt and decrypt messages.

There are many applications that we can choose, for this example we will use Gpg4win which is free, based on the OpenPGP standard. By default, it includes Kleopatra that is more complete and whose use is similar, but we chose GPA for this guide since we find it more simple and didactic. In the data that you are going to ask us next, it is not necessary that we place our real information.

In fact, it is quite common to place a false name and email address. It is a normal behavior among people who are extremely jealous of their privacy. It will also ask if we want to create a backup of our password, which is always advisable.

A few seconds after filling in the data, you will ask us to generate a password for our private key. It would also be ideal that it is not the same password that we use for other applications. If we have selected the option to save a backup, it will ask us where we want to locate it. After this, the key has been created. So he will request the password to be able to import it into our key manager.

Once done, we will see that the key already appears on our keychain with the data that we have placed.

Encrypting and Decrypting Text with PGP

If we place ourselves on the key we have just created, we can see below in its details a very important message: the key has a secret part that resides only in the device where we created or imported itanother public one which we can publish for others to encrypt messages just for us and serves for certification, signing and encryption.

What does this mean? We can not only encrypt and sign messages with it but also decode those that are sent to it. Being a bit lost at this point is normal if you have never worked with these security protocols, but with the exercise below, we will take a little more practice.

The first thing we need to send an encrypted message through PGP is to know the public key of the recipient. People who are available to receive encrypted messages usually post their public keys on their social profiles or websites. Once we have the public key of whom we are going to write, we save it in a.

This will open a dialog box where we must locate the mentioned. Once this is done, it will give us a message confirming the import, and we will see the key on our keychain. As seen in the previous image, we now have two keys.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

You should receive Adele's response after a short time period. Most e-mail programs also have special program extensions "plugins"which can be used to perform the encryption and decryption process directly in the e-mail program.

You can read this section now, or later when you need this function. Start MS Outlook and open Adele's response e-mail. Until now, you have only known Kleopatra as a certificate administration program. However, the program can do much more than that: It can control the actual GnuPG encryption software and hence not just manage your certificates but also take care of all cryptographic tasks with GnuPG's assistance.

Kleopatra provides the visual user interface, hence the dialogs which you as the user see while you encrypt or decrypt e-mails. Hence Kleopatra processes Adele's encrypted e-mails. To decrypt the message, Kleopatra will now ask for your passphrase that protects your private key. Enter your passphrase. The decryption is successful if you do not see an error dialog! You can now read the decrypted e-mail. Adele's decrypted response will look something like this 4 :.

In the next chapter, you will import this certificate and add it to your certificate administration. You can use imported public certificates at any time to encrypt messages to the people you are corresponding with, or to check their signed e-mails.

The application is a. The application run every week day in the evening at 6h30pm and sometimes the CMD line return the message: no secret key. The application failed because the file was not decrypted.

But it doesn't failed every evening, just random evening. It looks totally random. The secret key is imported in Kleopatra and it work fine with other application that run in the morning. And it work fine when I used it. We fix the problem. We must not log off the application user. If we log off the user, one key is not working, but the others are working. I've been wrong before. You might notice something out of place with your private decryption keys.

For example, if the key is listed as either. Then it's a primary or sub respectively key located on a smart card for storage. If the card, for whatever reason, isn't in the machine when the app runs it'll fail to decrypt. If the keys are stored on removable or unreliable media then that could also result in a failure to decrypt. Check that the item failing to decrypt was encrypted properly. If there is some secondary recipient necessary for the app to run there may be a required key that you don't know about I gather from your post you didn't create this app, just maintain it.

It may even be that the app is trying to decrypt a different file erroneously, but that kind of thing can only be found out by stepping through your source code and resident files.
