Data Encryption Standard (DES) is a block cipher algorithm that creates plain text in blocks of 64 bits and transform them to ciphertext using keys of 48 bits. It is a symmetric key algorithm, which defines that the similar key can be used for encrypting and decrypting information.The encryption phase ... Read More

An encryption key is a random string of bits produced explicitly for scrambling and unscrambling information. Encryption keys are designed with algorithms designed to provide that each key is unpredictable and unique.In cryptography, an encryption key is a string of characters used in consolidation with an algorithm to change plaintext ...

In DES, it is a symmetric-key block cipher introduced by the National Institute of Standards and Technology (NIST). DES was introduced as FIPS 46 in the Federal Register in January 1977.NIST can represent DES as the standard for use in unclassified software. DES has been the most broadly used symmetric-key ...

Encryption is the procedure of changing plain text into ciphertext, i.e., changing the text from readable format to non-readable format to protect the conversation among two parties or from the unauthorized person.A private key can be used to fastly encrypt the plain text. There are several techniques and algorithms have ... Read More

ConfusionConfusion defines making the relationship between the key and the cipher as difficult and as included as possible. In other words, the technique provides that the ciphertext provides no clue about the plaintext.In this regard, the relationship between the data of the cipher text and the value of the encryption ...

There are some techniques of Data Encryption are as follows −DES − DES stands for Data Encryption Standard. The Data Encryption Standards (DES) algorithm was invented by IBM in the early 1970s. It accepts the plaintext in 64-bit blocks and transform it into the ciphertext that need the 64-bit keys ... Read More

Password salting is a form of password encryption that includes appending a password to a given username and thus hashing the new string of characters. This is generally done through an MD5 hashing algorithm.Password-salting is generally found within Linux operating systems, and it is usually considered a more secure password ... Read More

Confusion defines that the key does not associate in a simple method to the ciphertext. In specific, each character of the ciphertext should be based on several elements of the key.In confusion, the relationship between the data of the ciphertext and the value of the encryption key is made difficult. ...

Hashing is basically a one-way cryptographic function. Because hashes are irreversible, understanding the output of a hashing method does not enable us to regenerate the contents of a file. It enables us to assess whether two files are same without understanding their contents.The use of hashing in information security and ... Read More

Diffusion is an encryption process where the authority of one plaintext symbol is spread over some ciphertext symbols with the objective of hiding statistical properties of the plaintext. A simple diffusion element is the bit permutation, which can be used frequently within DES. AES need the more advanced Mix-column process.Ciphers ... Read More
