Like we explained, PGP uses two keys – public and private key to encrypt and decrypt an email message.In the Terminal, type gpg -gen-key; Next, you can choose your RSA key length, which can be from 1024 to 4096 bits long. The longer the key, the more secure it will be; You ...

Ensure that your Windows user account has been set up with apassword that is strong and hard to crack. Using EFS requires your user account to have a password, and unless that password is strong, it might be brute forced by someone with physical access to the computer. Your file encryption...
How does Linux encrypt my data?Traditionally in Linux a beefed-up loopback device was used to mount a file. This loopback device then did de-/encrypt the data passing through to it. There were several different and incompatible versions of these loopback encryption engines, most supporting ...

To open an encrypted file, the process is similar. Right-click on it, selectServices>OpenPGP: Decrypt Filesand voila! The file is decrypted. If we are referring to any of themacOS devices, they secure all the data very well indeed. So leaks are rare, because their systems are truly rob...
PGP encryption is based on apublic key protocol, where a key pair (a public and a private key) is used to encrypt and decrypt messages. The public key is available to potential email contacts and is directly transferred or uploaded on an external key server. This key enables your contacts...
