Cryptography is the study or science of techniques of secret writing and message hiding. Cryptography constitutes any method in which someone attempts to hide a message, or the meaning in some medium. One specific element of cryptography is encryption, which hides the data or information by transforming it into an undecipherable code. Encryption uses a specified key to perform the data transformation. The length of the key for the encryption can vary from being very short to extremely long and the length of the message being encrypted.
Encryption is used in everyday life most commonly used among transactions over insecure channels of communication. The protection of data being transferred between ATMs and the bank, and the use of cell phones is the most common everyday encounter with encryption. To encrypt and dec...

...re not able to break the code.
Arther Scherbius invented the Enigma, an electro-mechinal machine used for encryption and decryption of coded messages. The machine allowed up to 10114 configerations, making the Egnima almost completely unbreakable. The biggest downfall of the Egnima was no letter could be replaced by itself, which allowed allied cryptographers to decrypt many messages sent by the Germans. During the time Allied forces used to crack the Egnima, the Japanese built their own encryption machine called Purple. The Japanese were very thourough in the destroying of their Purple machine; not one complete Purple machine has been recovered. An American team broke Purples code and were now able to intercept Japanese secrets during World War II.

- Decrypting Cryptography Cryptography is the study of techniques and implementation dedicated to the solving of complex problems. Today, its primary use is to protect sensitive information by maintaining the privacy of communications. In general, the secret information is transformed into an altered text by a process referred to as encryption, thus preventing the message from being read by anyone besides the intended receiver. It is this cipher text that is transmitted to the intended recipient, who must use the proper key to reverse the process, that is convert the encoded message back into its plain text form....

- Abstract: The use of encryption by individuals is growing at a tremendous rate, and since 1991 cryptography issues have engulfed both the U.S. government as well as the computing industry. One of the most controversial of these issues is whether encryption should be made supremely secure to the highest-level current technology will allow, or whether a "master key" should be locked away somewhere, only to be used when absolutely justified. Both sides of the issue have their benefits and detriments; the problem is finding the middle ground that will provide the greatest benefit to society.... [tags: cryptography issues]
