See How you Rank Data Risk Assessment Non-intrusive, hassle-free.At the highest level, this is how PGP encryption works: In this guide, we’ll show you how.PGP shares some features with other encryption systems you may have heard of, like Kerberos encryption (which is used to authenticate network users) and SSL encryption (which is used to secure websites).At a basic level, PGP encryption uses a combination of two forms of encryption: symmetric key encryption, and public-key encryption.In order to understand how PGP works, it’s useful to look at a diagram:The mathematics behind encryption can get pretty complex (though you can take a look at the math if you like), so here we’ll stick to the basic concepts.

So by encrypting the symmetric key using the (asymmetric) public-key system, PGP combines the efficiency of symmetric encryption with the security of public-key cryptography. Using symmetric encryption requires, though, that a sender share the encryption key with the recipient in plain text, and this would be insecure. Public key cryptography is much, much slower than symmetric encryption (where both the sender and recipient have the same key). Why would we encrypt the encryption key itself?Well, the answer is pretty simple. PGP Encryption UsesThere are, essentially, three main uses of PGP: If you are communicating to users outside of ProtonMail, you need to send them your public key first.And so, although the message was sent securely, the recipient does not have to worry about the complexities of how this was done. The email will look like this (the email addresses have been blurred for privacy reasons):ProtonMail – like most email clients that offer PGP – hides all of the complexity of the encryption and decryption of the message. You will see a padlock icon on the subject line of their emails. The PGP system was originally designed, in fact, by a peace and political activist named Paul Zimmerman, who recently joined Startpage, one of the most popular private search engines.Today, the popularity of PGP has grown significantly. In the early years of PGP, it was mainly used by activists, journalists, and other people who deal with sensitive information. But let’s take a brief look at all three Encrypting EmailsAs in the example above, most people use PGP to send encrypted emails. Encrypting files stored on your devices or in the cloud.Of these three uses, the first – sending secure email – is by far the dominant application of PGP. Verifying the identity of the person who has sent you this message. This can indicate either the sender is not who they say they are, that they have tried to fake a Digital Signature, or that the message has been tampered with. If even one character of the message has been changed in transit, the recipient will know. This is then encrypted using the sender’s private key.The recipient of the message can then decrypt this data using the sender’s public key. This generates a “hash function,” another algorithm that can convert a message to a block of data of fixed size. If a journalist is unsure about the identity of a person sending them a message, for instance, they can use a Digital Signature alongside PGP to verify this.Digital signatures work by using an algorithm to combine the sender’s key with the data they are sending. Digital Signature VerificationA related use of PGP is that it can be used for email verification. How tosearch for words on macDo I Need Pretty Good Privacy Encryption?Whether you need to use PGP encryption will depend on how secure you want your communications (or files) to be. This software offers PGP encryption for all your files, whilst also hiding the complexities of encryption and decryption processes. Since then, Symantec has become the dominant vendor of PGP file-encryption software through such products as Symantec Encryption Desktop and Symantec Encryption Desktop Storage. In fact, this algorithm is so secure that it has even been used in high-profile malware such as the CryptoLocker malware.Back in 2010, Symantec acquired PGP Corp., which held the rights for the PGP system. Because the algorithm used by PGP – normally the RSA algorithm – is essentially unbreakable, PGP offers a highly secure way of encrypting files at rest, especially when used alongside a Threat Detection and Response Solution. This is changing – thanks to off-the-shelf solutions that we will come to shortly – but using PGP can add significant extra work and time to your daily schedule. Cons of PGP EncryptionThe biggest con of PGP encryption is that it is not that user-friendly. In short, it is essentially impossible for anyone – be they a hacker or even the NSA – to break PGP encryption.Though there have been some news stories that point out security flaws in some implementations of PGP, such as the Efail vulnerability, it’s important to recognize that PGP itself is still very secure. That’s why it is still used by journalists and activists, and why it is often regarded as the best way of improving cloud security. Pros of PGP EncryptionThe major pro of PGP encryption is that it is essentially unbreakable. Their subject lines are not encrypted either, so you shouldn’t put any sensitive information there. Unlike anonymous browsers using proxy servers or working through a VPN to hide your true location, emails sent through PGP can be traced to a sender and recipient. In terms of storing data, anonymisation can be a good alternative to encryption and can be a more efficient use of resources.Finally, you should be aware that PGP encrypts your messages, but it doesn’t make you anonymous. There are encrypted messaging apps like Signal, for instance, that offer encryption that is more straightforward to use. This means that businesses considering a move to PGP will need to provide training.For that reason, many businesses might want to consider alternatives. Symantec, for example, offers PGP-based products such as Symantec File Share Encryption for encrypting files shared across a network and Symantec Endpoint Encryption for full disk encryption on desktops, mobile devices and removable storage. In recent years we have also seen the emergence of a number of online email systems that include PGP by default (the most famous being ProtonMail).For those of you looking to use PGP to encrypt your files, there are a number of large-scale software solutions available. There are add-ons like this available for Thunderbird, Outlook, and Apple Mail, and we will describe these below.
