This article will explain the difference between let and var in the Swift language. Most of the time, we deal with different data types in any programming language. However, we need to identify values by name. These names are called variables. Like C, Swift uses variables to store and refer to values by an identifying name. Swift also makes extensive use of variables whose values can’t be changed. These are known as constants. They are more powerful than constants in C. Constants are used throughout Swift to make code safer and clearer in intent. This is because you work with ... Read More
A cybersecurity consultant supports the prevention of cyberattacks and other threats to their client's data. To fight against attacks on businesses' networks and computer systems, cybersecurity consultants analyze vulnerabilities, assess security concerns, evaluate risk, and execute solutions. Before building and implementing cybersecurity defenses, a client hires professional consultants to assess the company's current securities. Who are Cyber security consultant? This might sound different from what you think about cybersecurity consultants. Typically, you might think of a very technical person sitting in front of a computer typing, not interacting with humans. This is a misconception people might have about cyber security ... Read More
Let's learn how to modify the colour of the error message in JavaScript while using jQuery form validation in this tutorial. Form validation is the process of verifying the pertinent data that the user has submitted in the input field. Here, we'll demonstrate how to use jQuery to validate a straightforward form with a login, password, and confirmed password. Necessary requirements − The fundamentals of HTML, CSS, JavaScript, and jQuery must be familiar to you. Method To start, you must create an index.html file that contains an HTML form containing input fields for the user name, email address, password, ... Read More
Cybercrime or Cyber-attack is a much-talked topic recently, and cybercriminals use different techniques to disable one or multiple computers & networks. Cyberattacks can disable computers and steal data. Cybercriminals use varied technologies to steal data from computers. Cyber-attacks include Phishing, malware, etc. Types of cyber Attacks Undoubtedly, cyber-attacks have substantial negative impacts. A cyber-attack can cause data breaches or data manipulation. Once an organization faces a cyber-attack, it can suffer huge losses. Today, all need to have a bit of knowledge of different types of cyber-attacks. Malware − Malware is a malicious virus, including spyware, Trojans, adware, etc. Trojan ... Read More
In this tutorial, we will talk about how we can use the plist in the application to store information. Let’s first understand what is plist. What is plist? The plist file is also called the property list and is used by operating systems (e.g. iOS) and users. The information is stored in a key-value format similar to a dictionary. A plist file can contain different types of values like strings, arrays, dictionaries, booleans, dates, data, and numbers, such as integers. Most of these types correspond to native Swift types, such as Array and Bool. You can also store nested arrays ... Read More
Cryptography and Cryptanalysis are two sides of the same coin. Cryptography disguises plaintext into ciphertext to prevent it from being comprehended by unauthorized people. Cryptanalysis seeks the reverse, i.e., to decode encryptions. Cryptanalysis is a fascinating area of study with great scope, which will be explored in this article. What is Cryptanalysis? Cryptanalysis is the process by which an encrypted code is decrypted without knowing/partially knowing the key, the original plaintext source, or the algorithm used. It is a scientific technique and a practiced art all in one. The method tries to retrieve the readable plaintext block from the encrypted, ... Read More
An object-oriented programming language called JavaScript was created to make developing websites more appealing and simple. The majority of the time, JavaScript is used to build dynamic, responsive elements for websites, improving customer experience. The most widely used lightweight, compiled, and interpreted programming language is JavaScript. It is additionally known as web page scripting language. It can be applied to both client-side and server-side programming. The interactions between an HTML/CSS document, or more properly the Document Object Model (DOM), and JavaScript are made simpler by the open-source JavaScript library known as jQuery. By defining the keywords, it makes navigating and ... Read More
The study and practice of decrypting and analyzing codes, ciphers, and encrypted text without using the actual key is known as cryptanalysis. It is a way of gaining access to the plain text content of a communication when the decryption key is unavailable. Define the relevant terms Cryptology is divided into cryptography (the creation of secret codes) and cryptanalysis (the study of cryptographic algorithms and the splitting of such codewords). A Cryptanalyst is someone who practices Cryptanalysis. Role of Cryptanalysis Cryptanalysis plays a significant role in the process of developing robust cryptosystems. If the designers of the cryptosystems did not ... Read More
A network application known as client-server architecture, sometimes known as a client-server model, divides workloads and tasks between clients and servers housed on the same system or connected via a computer network. Client-server architecture often consists of workstations, PCs, or other devices belonging to many users that are linked to a central server over the Internet or another network. When the server receives a request for data from the client, it complies and transmits the requested data packets back to the user. A client sends a request using a network-capable device, the server accepts and processes the request, and then ... Read More
