- Cryptocurrencies are the digital media of exchange which use cryptography and shared transaction ledgers to create a secure, anonymous, traceable and potentially stable monetary system. Cryptocurrencies take their name from their use of cryptography. Cryptography is the study of the methods of encrypting information, primarily with the intention of sending a message securely and privately but also for tasks such as data security and authentication.

- Protect a Password Database with a One-way Hash. A one-way hash function is a cryptographic algorithm that turns an arbitrary-length input into a fixed-length binary value, and this transformation is one-way, that is, given a hash value it is statistically infeasible to re-create a document that would produce this value. There are three widely used hash algorithms: MD4, MD5, and SHA.

What does a Cryptographer do? A cryptographer is one who practices or studies cryptography, a field primarily involved with keeping secret information secret. Modern cryptography is mostly concerned with encrypting digital information, such as e-mail, to protect it as it's sent from one digital source to another.

Cryptography There are various types of algorithms for encryption, some common algorithms include: 1  Secret Key Cryptography (SKC) - Here only one key is used for both encryption and decryption. This type of encryption is also referred to as symmetric encryption. 2  Public Key Cryptography (PKC): Here two keys are used.

- Encryption is the process of converting a plaintext message into ciphertext which can be decoded back into the original message. An encryption algorithm along with a key is used in the encryption and decryption of data. There are several types of data encryptions which form the basis of network security. Encryption schemes are based on block or stream ciphers.

What does âencryptionâ mean? The encryption algorithm is the chain of calculations that determine what ways the input plain text will be transformed into the output ciphertext. In the simple example above there was only one calculation carried out, which moved each letter of the message one forward in the alphabet.

- An algorithm is a well-ordered collection of unambiguous and effectively computable operations that when executed produces a result and halts in a finite amount of time [ Schneider and Gersting 1995 ]. With this definition, we can identify five important characteristics of algorithms.1  Algorithms are well-ordered.hile these simple algorithms are fine for us, they are much too ambiguous for a computer. In order for an algorithm to be applicable to a computer, it must have certain characteristics. We will specify these characteristics in our formal definition of an algorithm.

- Many disorders can cause eye redness. Some are emergencies, but others are mild and go away without treatment. The degree of redness does not indicate the seriousness of the disorder. The presence of eye pain or vision problems is more likely to suggest a serious cause. The most common causes of eye redness are.

Cryptographic hash function A cryptographic hash function is considered insecure from a cryptographic point of view, if either of the following is computationally feasible: 1  Finding a (previously unseen) message that matches a given hash values. 2  Finding  collisions , in which two different messages have the same hash value. hash function takes a string of any length as input and produces a fixed length string which acts as a kind of signature for the data provided.

Cryptography/Hashes Such processes behave similar to a hash function and so are typically called cryptographic hashes. These hashes are used in serving authentication and integrity goals of cryptography. A cryptographic hash can be described as and has property that the hash function is one way.A given hash value can not feasibly be reversed to get a message that produces that hash value. hash function is the implementation of an algorithm that, given some data as input, will generate a short result called a digest. For Ex: If our hash function is 'X' and we have 'wiki' as our input... then X('wiki')= a5g78 i.e. some hash value. Qualities of a good hash function are.

cryptography Cryptography is closely related to the disciplines of cryptology and cryptanalysis. Cryptography includes techniques such as microdots, merging words with images, and other ways to hide information in storage or transit.owever, in today's computer-centric world, cryptography is most often associated with scrambling plaintext (ordinary text, sometimes referred to as cleartext) into ciphertext (a process called encryption), then back again (known as decryption). Individuals who practice this field are known as cryptographers.

Counting sort Counting sort. In computer science, counting sort is an algorithm for sorting a collection of objects according to keys that are small integers; that is, it is an integer sorting algorithm. It operates by counting the number of objects that have each distinct key value, and using arithmetic on those counts to determine the positions of each key value in the output sequence. Its running time is linear in the number of items and the difference between the maximum and minimum key values, so it is only suitable fo

Cryptography More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography.

Encyclopedia The conversion of data into a secret code for transmission over a public network. Today, most cryptography is digital, and the original text (plaintext) is turned into a coded equivalent called ciphertext via an encryption algorithm. The ciphertext is decrypted at the receiving end and turned back into plaintext.

Symmetric-key algorithm Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext.The keys may be identical or there may be a simple transformation to go between the two keys.ncrypting a message does not guarantee that this message is not changed while encrypted. Hence often a message authentication code is added to a ciphertext to ensure that changes to the ciphertext will be noted by the receiver. Message authentication codes can be constructed from symmetric ciphers (e.g. CBC-MAC).

encryption encryption - Computer Definition. The art or science, or system, of coding or ciphering data into symbolic form to disguise, and thereby secure, the contents of a message. Generally in the form of firmware, rather than software, encryption logic commonly both scrambles and compresses message units (e.g., blocks or packets) prior to transmission.

Cryptographic hash function A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone.These one-way hash functions have been called the workhorses of modern cryptography.The input data is often called the message, and the hash value is often called the message digest or simply the digest.The ideal cryptographic hash function has four main properties: 1  it is easy to compute the hash value for any given message. 2  it is infeasible to generate a message from its hash.ne of the main applications of a hash function is to allow the fast look-up of a data in a hash table. Being hash functions of a particular kind, cryptographic hash functions lend themselves well to this application too.

- 1. Introduction 1.1 K-means algorithm: K-means clustering is a method of cluster analysis which aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean.It is one of the simplest unsupervised learning algorithms that solve the well known clustering problem.The k-means algorithm is an evolutionary algorithm that gains its name from its method of operation. The algorithm clusters observations into k groups, where k is provided as an input parameter.It then assigns each observation to clusters based upon the observation’s proximity to the mean of the cluster.t is one of the simplest unsupervised learning algorithms that solve the well known clustering problem. The k-means algorithm is an evolutionary algorithm that gains its name from its method of operation. The algorithm clusters observations into k groups, where k is provided as an input parameter.
