How does encryption work?
When you use encryption, your data gets converted into meaningless symbols by using a key, which is nothing but the algorithm that helps you to encrypt or decrypt data.
The more random the method of key conversion, the stronger the encryption will be. A pass phrase (or password) generally needs to be easy to remember, so it has significantly less randomness than its length suggests. For example, a 20-letter English phrase, rather than having 20 x 8 = 160 bits of randomness, only has about 20 x 2 = 40 bits of randomness.
So, cryptographic software converts a pass phrase into a key through a process called 'hashing'' or 'key initialization'.
At the heart of the process is the algorithm (or method), which is devised so as to make deciphering the encrypted file impossible without using the secret key. Some of the popular encryption algorithms include Blowfish, DES, Diffie-Hellman, IDEA, RC4, RSA and Skipjack. Many of these use 64 and 128-bit encryption systems i.e. devise keys of 2*64 or 2*128 length.
The Blowfish encryption algorithm on which CryptoExpert is based, was specially designed to encrypt data on 32-bit microprocessor. It is significantly faster than DES and GOST when implemented on 32-bit microprocessors, such as the Pentium or Power PC.
Is encryption really safe?
An ordinary user may find it difficult to unscramble even a simple algorithm. However, experts using sophisticated methods can employ a number of means to break an algorithm. The most common of these is "brute force" wherein a number of computers are simultaneously employed to break the code by a "trial and error" system which physically checks all possible combinations (or possible passwords).
However, a well developed encryption system can withstand even such brutal attacks. Encryption based on the algorithms mentioned above are generally immune to these kinds of attack assuming that no backdoors (or bugs) exist in the program. Calculations show that the period of time required to crack them through brute force is gigantic (at times in the range of thousands of years).
Statistically speaking, if 100 billion computers are used to break a 3DES (three 64-bit keys used together on a single password) key using brute force, they would need to process data continuously for an approximate of 457,351,814,728 years.
I'm sure that clears up any remaining doubt about the effectiveness of ciphers or encryption as a whole.

I have used a better software called WinEncrypt CryptArchiver from www.WinEncrypt.com which has all these features in the free version, and also feature to encrypt USB drives, and create self-extracting encrypted .exe files. This is also a free version.

arun madan, Rigndael algorithm is only current AES By the way there are too much good open source softwares like true crypt are there, so why this commercial version? In true crypt we can use about 10 algorithms including AES 256 and we can create "hidden volume" in which we can hide more sensitive information in case somebody retrieves the primary password.

This one is good but for simple security u can use "Hide files & folder".i m using it for a long and it's good enough to secure my files and above all the program hides itself also. u can't find it in "Add or remove programs" so nobody gets a hint about it.

dear here we r not talking about applying simple attribute to file to hide it, we r talking about organizational business security a complex algorithm of making passwords. TRY BESTCRYPT ITS FAAR BETTER THAN THIS SOFTWERE . FOR FOR ENCRYPTING PASSWORD BEST ALGORITHM IS AES METHOD.

Good info... The cost of full version is also good.. Another software which I had used which costs more & provides these features is DriveCrypt... But its more complex for new users... Will definitely try this one...Anyway for small data this Lite version seems OK for most...
