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 (unencrypted information) into ciphertext (encrypted information) and vice versa for decryption algorithms.It can change data so that it occurs random and “locks” it so that only the corresponding key can decrypt it. Keys can also define transformations in other algorithms, including digital signature schemes and message authentication codes. An encryption ... Read More

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 been produced to encrypt the encryption. For instance, substitution techniques, transposition techniques, MD5 algorithm, SHA algorithm, IDEA algorithm, etc.Data encryption is an approach of securing information confidentiality by converting it to encoded information, known as ciphertext. It can only be decoded with a unique decryption key, produced either at the ... Read More

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 block cipher because its publication. NIST later issued a new standard (FIPS 46-3) that confirm the use of triple DES (repeated DES cipher three times) for future software.The DES has a 64-bit block size and need a 56-bit key during implementation (8 parity bits are deprived off from the complete ...

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 to encrypt the information. The algorithm need the same key to encrypt and decrypt the information.DES is a symmetric key algorithm can encrypt digital data. Its short key length of 56 bits renders DES too insecure to secure most current applications that is based on encryption.Triple DES − Triple DES ... 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 has to remain as difficult as applicable. It is completed by spreading out the single plaintext digit over several Ciphertext digits, including when a single bit of the plaintext is changed.In confusion, it should influence the complete cipher text or change should appear on the complete cipher text and the ...

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. It is completed by substitution.For example, suppose that it can have a Hill cipher with an n x n matrix, and suppose that it can have a plaintext-ciphertext pair of length n2 with which it is able to solve for the encryption matrix.If it can change one character of the ...

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 encryption model than some models used within the several Microsoft distributions.When a username has been produced, the user generally creates a password to associate with this username. After the user has submitted the password to the salt-allowed system, the system add the password to the username. Therefore, the new string ... Read More

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 internet authentication is a general practice. For instance, it can be used to safely save passwords in a database, but can also provide the security of other element of data such as files and documents.Hash algorithms are frequently used to support a digital fingerprint of a file’s contents used to ...

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 can only implement confusion, including the Shift Cipher or the World War II encryption machine Enigma are not protected. Neither are ciphers which only implement diffusion. However, through the concatenation of such service, a strong cipher can be constructed.Diffusion means that if it can change an individual bit of the ... Read More

There are some popular Encryption Algorithm are as follows − Triple DES − Triple DES was intended as a successor to the once generally used Data Encryption Standard (DES) algorithm. This symmetric-key approach of data encryption was create obsolete by the hackers who continually exploited its vulnerabilities.Triple DES succeeded that develop into the most broadly used symmetric algorithm in the industry. The algorithm need a 56-bit individual key with the total key length inserting up to 168 bits. Because it is consecutive encryption, there is a middle-level vulnerability that reduce its protection to the level of a 112-bit key. Advanced Encryption Standard ... Read More
