Encryption by AES

i-effect^® *CRYPT encrypts ZIP archives according to AES ( Advanced Encryption Standard ) combinated with the compression module *ZIP. Encrypted data can be decyphered and edited cross-platform anytime with every AES compatible application.

At the end of the ninetees reasonable doubts on safety of DES ( Data Encryption Standard ) were being confirmed in a test deciphering. This has been the beginning of the triumphal processing of AES (also the so called Rijndael algorithm) becoming the leading crypto-system.

AES is a block cipher which dispose of a viariable block size valued 128, 192 or 256 bit and a variable length of key valued 128, 192 or 256 bit. This means in decimals:

3.4 x 10^38 possible 128 bit key
6.2 x 10^57 possible 192 bit key
1.1 x 10^77 possible 256 bit key

Assuming that a machine recovered a DES key in a second (i.e., try 7.2 x 10^16 keys per second), then the machine would take approximately 149 thousand billion years to crack a 128 bit AES key. No wonder that in the United States AES is accredited for governmental documents with strictest degree of secrecy.
