Let’s dive directly into the topic
Bitcoin on May 19 declined almost 30 percent to $31,000, wiping out more than $500 billion in value from the coin’s peak market value.
According to reports, another cryptocurrency Ethereum also tanked more than 40 percent whereas Bitcoin fell about 9 percent to as low as $38,940 and slipped below a key 200-day moving average.
The Decline in the two most Traded Crypto-currencies almost lie in 2 reasons-
China’s announcement on Tuesday that it is banning financial institutions and payment companies from providing services related to cryptocurrency transactions.
Also, cryptocurrencies were sparked last week…
Cors is a short term for Cross-Origin Resource Sharing, which is indeed an HTTP Header-based mechanism that helps a server to allow access only for specific origins or all origins(*) as per requirements of a project.
In this tutorial, we would completely study how we can handle CORS in the Express JS framework. First of all, we gonna study the 2 important types of XML HTTP Requests which come under the CORS-
Simple Requests are those requests which don't trigger CORS preflight. These requests need access to GET or POST methods. …
Do you know that there are more than 2 Billion websites on the World Wide Web, but less than 400 Million sites are Active. And unexpectedly 11.8 Million websites rank in Google Search Engine Result Pages(SERP’s).
Indeed, almost all of these 11.8 Million websites uses Best Search Engine Optimization (SEO) tactics which defended the 400 Million sites. Important Search Engine Optimization techniques involves
If these 6 elements played as Professional can lead a website into SERP’s, but is this all we do to…
In this tutorial, you will learn everything about how you can use JSON Web Tokens (JWT) in Node.js to authenticate users. If you are not familiar with JWT, you can follow the link here — this explains everything about JWT with many interesting examples.
In this tutorial, we will create APIs for signup, login, and logout using Node.js. Firstly, let’s recall the basics of JWT.
JW-Token consists of 3 parts:
The header includes the type of algorithm used to generate tokens. It looks like this:
Payload is nothing but the user data.
We have often heard this wording a lot times as, Signup with Google or Signup with Facebook. This sounds us convenient and we often click such buttons to save our time. In this tutorial, we would built an Amazing Web Application using React JS Framework which would Authenticate Users using the Auth0 Authorization Framework.
Yes, you have got there, how we gonna use Authorization Framework to Authenticate users?
Nowadays, big-tech companies use the concept of OAuth to Authenticate users in much convenient manner. We gonna learn the same, in this tutorial.
In this tutorial, you would understand everything about how OAuth exactly works, basic terms of OAuth, and various important flows. Let’s know from the beginning.
OAuth is short for, Open Authorization for access delegation commonly used in services to access data or resource from another service. To know a much more detailed understanding of OAuth, you can refer to this.
Now, let’s understand the important aspects of Terminologies. Here are some of the terms which are necessary to start with Flows of OAuth, let’s look at them one by one-
Resource is something we all know, a term…
In this tutorial, we would understand everything about what exactly OAuth is, and also we would look at analogy to understand much clearly.
Let’s be frank, OAuth is ultimately known as Open Authorization. OAuth is a Standard for access delegation, commonly used for websites or applications which have to access to data of other website accounts without sharing any passwords. To speak clearly, OAuth is the access of the data from one service to another service without sharing any passwords.
Now, let’s look at an example which can make you understand much clearly,
Imagine a Rich Guy came…
JWT or JSON Web Token is an open standard (RFC 7519) which is used to securely transfer information between two parties.
To understand the detail concept of JWT, it’s very important to first know about Session tokens.
Session Tokens are an encrypted unique strings that are used to identify Session Instances. Look at the understandable example below-
Think of a Customer Care Dept. in a city, if a person(A) enters into it who has any queries to speak with representatives. Initially a person would speaks about all his problems and queries, then normally the care dept. would note down all…
