With PGP, they can send or receive secure emails and files, verify the identity of the person that has sent the message, and encrypt files and folders stored on their device or the cloud. That is why numerous people use PGP Desktop as part of their email client. The sender must use this public key to encrypt the message, while the recipient will use the previously generated private key to open the email.Īlthough the process sounds complicated, it’s easy to execute in action. That means, if you wish to send someone an encrypted email, the recipient must first generate a private and public key and then send the public key to you. PGP Desktop uses asymmetric encryption to protect data. What types of files can I encrypt using PGP Desktop? Once encrypted, all files get locked and can no longer be accessed remotely by hackers or viruses. From here, you can select the keys you wish to use and share their details with recipients of the encrypted data. Once launched, the program will ask you to specify the duration of the key, add the hashing and encryption algorithm, and then create a passphrase for the container holding these keys.Īfter you’ve gone through the process of creating PGP keys, you can access them via the application’s primary window. These keys will be used to encrypt data and later act as digital signatures for decrypting the protected information. To begin using the software, you must first create a set of private and public keys. Once you download PGP Desktop and install it on your PC, you’re taken through the process of creating PGP keys, which you need to further protect using a password. You should know that recent studies have shown that with modern hard drives, single pass algorithms are as secure as multiple on-track overwrite passes.PGP Desktop is a Windows application that lets you encrypt data such that only people who have access to the corresponding security credentials can access it. Which algorithm is best for you will depend on how much time you have and on how paranoid you are. Therefore, run this function only when you intend to take a coffee break anyway.įile Shredder supports four different algorithms to wipe files from the hard disk: Simple One Pass, Simple Two Pass, Secure Algorithm with 7 passes, DoD 5220.22-M, Guttmann algorithm with 35 passes. Note that this will keep your hard drive busy for quite some time. This will just overwrite unused disk space to ensure that files that have been "deleted" before can no longer be recovered. Once you have added all files to be erased, you can shred these with one mouse click.Īnother useful feature of File Shredder is the " Shred Free Disk Space" function. You have to first close and re-open the tool. If you already have opened File Shredder, newly added files won't show up right away. File Shredder will add those files to a list that you can view in its user interface. Thus, if you want to erase multiple big folders, you had better choose "Remember to be deleted" later from the context menu. This can take some time for large amounts of data. To "shredder" files, every byte on the disk has to be overwritten. This can be useful if you want to erase a large number of files. You can also mark files to be deleted later.
