PGP BitLocker TrueCrypt File Encryption

PGP Bitlocker Truecrypt  – Some of the symmetric encryption types I found were Blowfish, Rijndael, Triple DES, Gost, and Standard AES.. The major differences in many of these listed is the how large the bit key is. Standard AES has been chosen by the National Institute of Standards and Technology as the standard for all encryption. Asymmetric algorithms are used encrypt and decrypt with different keys. Data is encrypted with a public key, and decrypted with a private key. In addition, asymmetric algorithms are extremely slow and are impartial to use them on large amounts of data.

How do these different approaches offer different types of projection (file encryption, disk encryption, and so forth)?

As stated above asymmetric is extremely slow to use on whole disk encryption but would be more suitable for a file encryption. Using commercial Linux server operating system you can use Linux Unified Key Setup-on-disk-format (LUKS) to encrypt the entire hard drive on installation using Advance Encryption Standard (AES). Enterprise and Ultimate versions of Microsoft Windows 7 ship with BitLocker, which is their version of the entire disk encryption.

Which product would you recommend to management for use throughout the organization?

Truecrypt has been noted as one of the most efficient whole disk encryptions. One reason it is tremendously successful and popular is it is completely free. Unlike PGP, which also offers extremely good protection is very costly for an organization; although, may be the best option for trade secrets or other extremely sensitive information. Unlike many algorithms such as BlowFish and BitLocker have been rumored to have backdoor programs, PGP and TrueCrypt are unhackable even by the United States Government’s finest.

Which product PGP BitLocker TrueCrypt would you consider adopting for yourself?

Unlike many corporations, I do not have extremely sensitive information. The likelihood someone will dedicate all the time and energy to break an encryption on my system is unlikely. I would probably default to the Windows built in whole disk encryption of BitLocker, and use the free PGP Desktop program for transferring any particularly sensitive information I may come across.
