In cryptology, Web of Trust (WOT) is the idea of securing the authenticity of digital keys through a network of mutual confirmations (signatures), combined with the individually assigned trust in the confirmations of others ("owner trust"). It is a decentralized alternative to the hierarchical PKI system. Public key encryption offers the advantage (compared to symmetric encryption) that the key … [Read more...]
How Digital Signature Can Be Generated
At its core, a digital signature is a cryptographic scheme that enables the verification of the authenticity and integrity of a digital message or document. It involves the use of mathematical algorithms to generate a unique digital fingerprint, or signature, for a specific piece of data. We have discussed the basics of digital signature in our earlier articles. In the case of digital signatures, … [Read more...]
Difference Between Electronic Signature and Digital Signature
Confusion between Electronic Signatures and Digital Signature is a common problem. When I write "Abhishek Ghosh" on a paper, you name it as "ink signature". If you write "Abhishek Ghosh" on S24 Ultra with my S Pen, that becomes an electronic signature. A digital signature is a cryptographic method which we have explained in our earlier article. While both terms are often used interchangeably, … [Read more...]
Who Needs Hardware Security Token for Authentication
In an era marked by increasing cybersecurity threats and data breaches, ensuring secure authentication mechanisms is crucial for individuals and organizations alike. While traditional methods such as passwords and PINs offer some level of security, they are susceptible to various vulnerabilities like phishing attacks, brute-force attempts, and password reuse. Hardware security tokens provide an … [Read more...]
Explanation of Digital Signatures With Example
In an increasingly digital world, the need for secure and trustworthy communication, transactions, and document management is paramount. A digital signature is an asymmetric cryptosystem in which a sender uses a secret signing key (the private key) to calculate a value for a digital message (i.e., any data). This value allows anyone to check the indisputable authorship and integrity of the message … [Read more...]

What is a Magic Number (With Code Examples)
In computer science, a magic number typically refers to a unique numerical value or code embedded within a file or data structure that serves a specific purpose. Magic numbers are often used to identify file formats, data types, or special conditions within binary data. A magic number has three meanings in programming: Originally from the Unix world, it is a special value that identifies a … [Read more...]
What is a Plug-in
A plug-in is an optional software component that extends or modifies an existing piece of software or a computer game. The term is sometimes also used as a synonym for "add-on" and "add-in". Plug-ins are usually installed by the user and then integrated by the corresponding main application during runtime. Plug-ins can't run without the main application. Software vendors often define … [Read more...]
What is XHTML (XHTML5) – Working Examples
The W3C Extensible Hypertext Markup Language (extensible HTML; XHTML) is a text-based markup language for structuring and semantically marking up content such as text, images and hyperlinks in documents. It is mostly a reformulation of HTML 4.0 in XML. In contrast to HTML, which was defined using SGML, XHTML uses the stricter and easier to parse SGML subset XML as the language basis. XHTML … [Read more...]
