What every encryption software requires is an effective password recovery mechanism. Secure and safe recovery mechanisms are essential for large scale deployment of any kind of encryption. The solution must be easy yet secure.

A challenge or Response password recovery mechanism allows the password to be recovered in a secure manner and is offered by a number of disk encryption solutions. When a challenge or response password recovery mechanism is used there is no need for the user to carry a disk with the recovery encryption key, no secret data is exchanged during the recovery process.  More importantly it does not require a network connected and can therefore be used in remote locations without any internet access and no information can be sniffed.

Another method of recovery is the ERI method or the Emergency Recovery of Information file password recovery mechanism.

An Emergency Recovery Information or ERI method provides an alternative if a challenge or response password recovery mechanism is not feasible or has implementation challenges.

ERI or Emergency Password Recovery Mechanisms have their own pros – It is cost efficient so pretty much anyone with the basic technical knowledge to do so can set it up without implementation difficulties. Like challenge recovery mechanism no secret data is exchanged in the recovery process and no information can be sniffed. It can work from a remote location without internet access.

That’s all for now folks!

Equipping your PC with a firewall and antivirus tool may keep out most hackers, but doesn’t guarantee your security. If someone gets physical access to your system (it’s stolen, say, or a computer repair technician is snooping around) then the best internet security suite will be no use at all, and there’s only one way to ensure you’re protected: Encryption.
Personally i use this open source encryption software called TrueCrypt. TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data is automatically encrypted or decrypted right before it is loaded or saved, without any user intervention.No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfiles or correct encryption keys. The entire file system is encrypted (such as file names, folder , contents of every file, free space, meta data and so on).I believe that all of us should have encrypted systems as they protect us from not only virtual  threats but also from snoops or people who just like messing around with personal files on your computer . for example your nosy college roommate who just wants to know where you have the hidden assignment for next days class.
just encrypting your system, drive or file will protect it from from normal users but if
you’re really interested in protecting your data from the government or hackers then use a password that is at least 20 characters long with alphanumerics and special characters. Also ensure that you use upper and lower case  characters AND never use personal information like a dogs name or your birthday as a part of your key!
if you followed everything i said above then CONGRATULATIONS!! you have a very secure device.
