Originally, it was used to enable individual users to communicate on bulletin board system computer servers.

PGP was one of the first public-key cryptography software publicly available for free. PGP aims to solve this and enhance email security by encrypting the data to make the communication method more private. PGP software was owned and sold by a company called PGP Corporation, which was founded in 2002 then sold to Symantec in 2010.Įmail is a prime attack method for cyber criminals who can easily forge messages using a victim’s name or identity. PGP was first designed and developed in 1991 by Paul Zimmerman, a political activist. TrueCrypt doesn't do whole-disk encryption, but it does offer a way to conceal the fact that an encrypted volume exists-although that handy feature isn't yet available on OS X and Linux.Pretty Good Privacy (PGP) is a security program used to decrypt and encrypt email and authenticate email messages through digital signatures and file encryption. I should also note here that a free volume encryption utility called TrueCrypt was released for OS X last week (it was previously available for Windows and Linux). A perpetual license for PGP Whole Disk Encryption 9.8 for Windows costs $149. Its whole-disk encryption utility for Windows in May 2005.

And a paper (click for PDF) published last year by Jacob Appelbaum and Ralf-Philipp Weinmann found other potential security weaknesses. Earlier versions of OS X didn't encrypt the swapfile used for virtual memory, meaning the password could in many cases be easily extracted. Some applications including Thunderbird save working copies of documents in an unencrypted area outside the home directory.Īnother problem with FileVault is that it hasn't always been implemented that securely. Without whole-disk encryption, Unix-derived systems including OS X store in unencrypted form details about VPN usage, login times, and what applications are installed in the default location. OS X already features FileVault, of course, but that focuses on encrypting the user's home directory. Right now there's no way for OS X users to encrypt their entire boot disks. This promises to be a boon for OS X users, especially laptop users who are more likely to lose their machines or run into snoopy border police and airport security guards who want to poke around the contents of their hard drives. Callas didn't want to elaborate on a shipping date, unfortunately. Jon Callas, PGP's chief technology officer, told me on Monday that the software is 'in active development' and will run on Intel-based Macs.

is planning to release a version of its whole-disk encryption software for Apple Macintosh computers running OS X.
