Here, we discuss several great PGP encryption app options thanks to which you can rest assured that private, confidential data you share with friends or someone else online remains safe and secure. Before we check out these apps, we should briefly discuss what is PGP encryption, how it works, and how it protects your private data.
PGP encryption that stands for Pretty Good Privacy is a powerful encryption technology that is used for encrypting, protecting emails and filers. In other words, this encryption technology delivers cryptographic privacy via its encryption program released back in 1991. The program was crafted by Phil Zimmermann and it works across a variety of platforms including desktop devices powered by macOS, Linux, and Windows.
Since its beginnings in 1991, Pretty Good Privacy has become the most used security and privacy stands when it comes to email technology and communication. When you have a reliable, safe to use PGP encryption app, you can easily encrypt as well as decrypt emails, text messages, and files with the main purpose of boosting the security of your private, confidential data.
What is a PGP Encryption App?
As mentioned in the previous section, Pretty Good Privacy is a computer program that grants authentication and cryptographic privacy for emails and other online communication channels. This technology always uses cryptography, hashing, and data compression alongside both asymmetric and symmetric keys in order to encrypt private, sensitive data that will be transferred across different networks.
The Pretty Good Privacy technology also combines public and private key cryptography features with every public key being associated with an email address and user name and every step of the encryption process features a unique algorithm. With a PGP encryption app, when you encrypt plaintext, the text is first compressed to boost cryptographic security, save disk space, and save some transmission time.
Public keys are traded among two parties while private keys are used for signing the content that has been encrypted. With a reliable, safe PGP encryption app and there are many great options out there, you can confidentially communicate with others online, protect your private messages as they travel from your device to the recipient’s device, and even check whether your messages have been altered or not. Further, we take a look at several great options if you are looking for a PGP encryption app that does the work the right way.
