Description: This particular algorithm is a brute force attack on the popular DES Encryption standard. The DES algorithm consists of 4 main classes which will be briefly discussed
-The first class takes into consideration the assumption that the in the inputs are in hex format. Therefore a method was created to convert the hex into binary so that it could be easily permuted.
-The second class takes the converted binary input and passes it through a variety of member permutation functions.
-The next class also known as the key class handles operations on keys that have not been permuted.
-The S-box functionality is provided by the last class.

Description: Digital Images and video encryption plays an important role in today’s multimedia world. Many encryption
schemes have been proposed to provide security for digital images. Usually the symmetric key ciphering algorithms
are used in encrypting digital images because it is fast and use the techniques for block and stream ciphers. Data
Encryption Standard is symmetric key encryption algorithm. In spite of the successful cracking of the data
encryption standard by massive brute force attacks, data encryption standard algorithm is an entrenched
technology and still useful for many purposes. In this paper, we use some of the image quality encryption
measuring factors to study the effect of data encryption standard algorithm in image ciphering. The results show
that the data encryption standard algorithm is fast and it achieves a good encryption rate for image ciphering using
different modes of operation.

Description: AES is the Advanced Encryption Standard, a United States government standard
algorithm for encrypting and decrypting data. The standard is described in Federal
Information Processing Standard (FIPS) 197.1
On January 2, 1997, The National Institute of Standards and Technology (NIST)
published a request for comments for the “Development of a Federal Information
Processing Standard for Advanced Encryption Standard.”2 NIST sought to “consider
alternatives that offer a higher level of security”3 than that offered by the Data Encryption
Standard (DES), which grew vulnerable to brute-force attacks due to its 56-bit effective
key length.AES candidates were required to support a symmetric block cipher that
supported multiple key lengths. The algorithm had to be publicly defined, free to use, and
able to run efficiently in both hardware and software
