8 Best PGP Encryption Software for Windows


Are you searching for encryption software for your system? Or do you want free, open-source encryption software for Windows? Then this article gives you good information about PGP encryption software because data encryption and decryption are essential in today’s world.

Phil Zimmermann developed Pretty Good Privacy (PGP) Encryption software in 1991. It is used for various purposes like encryption, decryption, signing, directories, whole disk partitions, etc. It works on the cryptology technique.

What is Cryptography?

It is also termed a synonym of encryption. It is a set of protocols studied and practiced for secured communication in an adverse environment. This technique prevents third parties from reading private messages.

PGP Encryption can be done through various steps. The algorithms support each step. These steps combine hashing, data compression, symmetric-key cryptography, and public-key cryptography. Each public key consists of two variables, i.e., username and e-mail address.

Background procedures for PGP Encryption are as follows:

  • Data is entered, and a random key is generated in the system.
  • Then, this random key encrypts the data.
  • This random key is also encrypted using a receiver’s public key.
  • Next, the encrypted message is generated, consisting of encrypted data and a random key.
  • Then, this encrypted message is sent to the receiver.

PGP encryption is beneficial to all users. It secures the message you are sending and the data, files, and folders stored in the network. Some applications of these are:

  • E-mails and attachments
  • Digital signatures
  • Disk encryption
  • Security of files and folders on the network
  • Batch file transfer and many more

Now, we will discuss in detail the best 8 PGP Encryption Software for Windows, which is open-source software and free. You can download it and use it for prevention and security purposes.
