Advanced AES Encrypter 0.0.1

Advanced AES Encrypter is a small application created to encrypt/decrypt files using AES (Advanced Encryption Standard).

About AES

In cryptography, the Advanced Encryption Standard (AES), also known as Rijndael, is a block cipher adopted as an encryption standard by the U.S. government. It has been analyzed extensively and is now used worldwide, as was the case with its predecessor, the Data Encryption Standard (DES). AES was announced by National Institute of Standards and Technology (NIST) as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001 after a 5-year standardization process (see Advanced Encryption Standard process for more details). It became effective as a standard May 26, 2002. As of 2006, AES is one of the most popular algorithms used in symmetric key cryptography. It is available by choice in many different encryption packages. This marks the first time that the public has had access to a cipher approved by NSA for top secret information.

Serpent was a finalist in the AES competition. The winner, Rijndael, got 86 votes at the last AES conference while Serpent got 59 votes, Twofish 31 votes, RC6 23 votes and MARS 13 votes.

The cipher was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, and submitted to the AES selection process under the name "Rijndael", a portmanteau of the names of the inventors. (Rijndael is pronounced, which sounds almost like "rain dahl").

Unlike DES (the predecessor of AES), AES is a substitution-permutation network, not a Feistel network. AES is fast in both software and hardware, is relatively easy to implement, and requires little memory. As a new encryption standard, it is currently being deployed on a large scale.
