Cryptography is used to ensure message security during transmission. An example is the use of codes to hide your identity and transaction details when purchasing goods over the internet via you credit card.
Encryption is used to protect your essential data and documents and with it you can also store your encrypted data in strong encrypted vaults and also get instant and reliable data security.
Any where concealing information is needed.

The most common application for encryption is in Internet browsing; whenever someone enters a "secure" website (indicated by shttp as the page protocol type) an encryption system is used to secure traffic between the user and the site.
Encryption would be a prime example. [excuse the pun!] Choosing a randomized trial would be another application.
Encryption
One interesting application of HUGE prime numbers is in encryption. Many systems used nowadays for encryption use more or less random prime numbers, of over a hundred digits each. This is by no means the only practical application of prime numbers. More examples of practical uses can be found here: http://en.wikipedia.org/wiki/Prime_number#Applications
People have developed many encryption algorithms. One particular encryption algorithm is the Rijndael algorithm, usually called the AES or Advanced Encryption Standard.
Encryption is converting plain text into cipher text . Yes, encryption can be cracked and then the text can be decrypted.
"Evaluating cryptography is difficult since without 'breaking' the encryption its hard to say whether one encryption is better or not. Pretty Good Encryption (PGP) is asymmetric, that is the encryption and decryption keys are different which may give it an edge on symmetric encryption."
Basic encryption (up to 256 bit encryption) software costs around $400 per year. Encryption softwares are not 100% foolproof.
what does the word skit stand for in encryption
Encryption
Mostly for performance - symmetric encryption is much much faster (order of magnitudes) than asymmetric encryption.
The top read application for a Blackberry phone is the push email system. Blackberries are the exclusive cell phone provider for secure communications in the Federal government due to their proprietary email system that allows high level encryption.
