DES is a strong encryption standard that works on a 64-bits plaintext block and restore a 64-bits ciphertext. Therefore, DES results in a permutation between the 264 possible arrangements of 64 bits, each of which can be either 0 or 1.DES has 16 rounds and it can use the same set ... Read More

SHA stands for secure hashing algorithm. SHA is a modified version of MD5 and used for hashing information and certificates. A hashing algorithm shortens the input information into a smaller form that cannot be learned by utilizing bitwise operations, modular additions, and compression functions.SHAs also help in revealing if an ...

DES stands for Data Encryption Standard. The Data Encryption Standards (DES) algorithm was invented by IBM in the early 1970s. It obtain the plaintext in 64-bit blocks and changes it into the ciphertext that need the 64-bit keys to encrypt the information. The algorithm need the similar key to encrypt ... Read More

There are various types of keys are as follows −Symmetric key −A symmetric key is one that can be used both to encrypt and decrypt information. This can define that to decrypt information, one should have the same key that was used to encrypt it.Symmetric encryption is generally more effective ... Read More

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

Key management define as managing cryptographic keys within a cryptosystem. It can manage with generating, exchanging, saving, using and replacing keys as required at the user level.A key management system will also contains key servers, user process and protocols, including cryptographic protocol design. The security of the cryptosystem is based ... Read More

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 ...
