Encryption is the conversion of information, called plaintext, into a ciphertext (also called cipher or keytext). A secret key is used, which may only be known to authorized persons. With knowledge of the key, the ciphertext can be converted back into the plaintext, which is called decryption. Encryption is used to maintain the secrecy of […] The post Basics of Encryption – Encrypt, Keys, Decrypt and Deciphering appeared first on The Customize Windows ..read more

In a world where climate change is intensifying and energy consumption is a growing concern, designing and building houses that stay cool without relying on air conditioning is becoming increasingly important.

A nonce is a word, a string of letters or numbers that is intended for use only once. In the past, nonce stood for a word that would soon be replaced by something better. In cryptography, a nonce is a random or pseudo-random number generated for a specific purpose and used only once within a […] The post Role of nounce in Cryptography appeared first on The Customize Windows ..read more

U2F (Universal Second Factor) is an industry standard for general-purpose two-factor authentication, based on adapted challenge-response authentication. In addition to an access password, it is used to prove access authorization, for example for web-based services, and can also be used in combination with digital personal documents to establish identity. The U2F specifications were developed by […] The post What is U2F (Universal Second Factor) of Security Tokens appeared first on The Customize Windows ..read more

Iris recognition is a method of biometrics for the purpose of authenticating or identifying individuals. For this purpose, images of the iris of the eye are taken with special cameras, the characteristic features of the respective iris are identified using algorithmic methods, converted into a set of numerical values (feature vector, or “template”) and stored […] The post How Iris Recognition Works appeared first on The Customize Windows ..read more

Crypto mining is the process by which new cryptocurrency coins are created and transactions are verified and added to the blockchain ledger. Miners use powerful computers to solve complex mathematical puzzles, known as proof-of-work (PoW) algorithms, in exchange for rewards in the form of newly minted coins and transaction fees. Popular cryptocurrencies like Bitcoin, Ethereum, […] The post Factors Influencing Profitability From Crypto Mining appeared first on The Customize Windows ..read more

A replay attack is a crypto-analytical form of attack on the authenticity of data in a communication protocol. In this case, the attacker sends previously recorded data to simulate a foreign identity, for example. Suppose Alice wants to prove her identity to Bob. They both know Alice’s secret password. Alice calculates the hash value of […] The post What is a Replay Attack? appeared first on The Customize Windows ..read more

Dash (Digital Cash), initially (2014–2015) also known as XCoin or Darkcoin, is an open-source peer-to-peer cryptocurrency that offers functionalities comparable to Bitcoin, but also beyond. Special attention is paid to data protection. For example, with Dash, unlike other cryptocurrencies, transaction information is not public; this is made possible by the PrivateSend (formerly Darksend) system. In […] The post Basics About Dash (cryptocurrency) appeared first on The Customize Windows ..read more
