Through this software, you can encrypt all of your important data , files , folders , etc. These additional software work with Kleopatra and provide additional features to it, especially added encryption features. The process of encryption used by this encryptor is quite similar to other software where first, you need to generate a key pair by providing the information like name , email , and passphrase password.
After that, you need to select file or files that you want to encrypt and press Encrypt button to start encryption. Similarly, at the time of decryption, you would be required to select the same key pair that you have used for the encryption and right password to decrypt files. Besides encryption and decryption features, this software also contains features like Export Secret Key , Change Expiry to set the expiry date of the key , Create Checksum Files , etc.
It is a free desktop tool that allows you to protect sensitive files , folders , etc. Conventional encryption methods use a single key or password to encrypt the information, while this PGP encryptor uses much safer dual-key asymmetric system.
Similar to encryption, you or another authorised user can also decrypt files with ease by selecting the right key pair and providing the correct password. Apart from encryption and decryption, you can also use this software to digitally sign and verify documents. An Integrated Key Manager is also present that allows you to quickly create , import , export , and manage keys. 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. 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. Of these three uses, the first — sending secure email — is by far the dominant application of PGP.
As in the example above, most people use PGP to send encrypted emails. In the early years of PGP, it was mainly used by activists, journalists, and other people who deal with sensitive information. 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. As more users have realized just how much information corporations and their governments are collecting on them, huge numbers of people now use the standard to keep their private information private. A related use of PGP is that it can be used for email verification. 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.
If even one character of the message has been changed in transit, the recipient will know. 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. A third use of PGP is to encrypt files. In fact, this algorithm is so secure that it has even been used in high-profile malware such as the CryptoLocker malware. This software offers PGP encryption for all your files, whilst also hiding the complexities of encryption and decryption processes.
Whether you need to use PGP encryption will depend on how secure you want your communications or files to be.
As with any privacy or security software, using PGP requires that you do a little more work when sending and receiving messages, but can also dramatically improve the resilience of your systems to attack. The major pro of PGP encryption is that it is essentially unbreakable. Symantec's Quick Start Guides:. Boot sectors, system files, and swap files are all encrypted.
Whole disk encrypting your boot drive means you do not have to worry if your computer is lost or stolen: to access your data, an attacker would need your encrypted drive's "passphrase", provided that the computer is not already booted.
PGP Zip allows you to create an encrypted, compressed, portable archive from any combination of files and folders. You can use a PGP Zip archive to send data to other people securely or to back it up securely. PGP Shredder completely destroys files and folders that you delete so that even file recovery software cannot recover them.
When you delete a file using the Recycle Bin on Windows systems or Trash on Mac OS X systems , it is not actually deleted; just the directory information pointing to it is deleted. PGP Shredder, however, immediately overwrites file's data multiple times.
The Symantec Encryption Management Server provides central administration of encryption applications, creation and delivery of configuration policy, reporting and logging, and management of PGP private and public keys. The biggest problem with Symantec Drive Encryption is even though the data on your hard drive is encrypted, after you log in and unlock the encrypted disk, your data is freely accessible.
Making sure that everyone uses a login password and has that password activated when the computer wakes up from sleep or the screensaver can help with that problem. However, on Windows, if you use Hibernate rather than Sleep , when your computer turns itself off, Symantec Encryption Desktop will protect your computer when it wakes.
