certificates and Domain Validated (DV) certificates. Both of them use the same data encryption while transferring sensitive data between two hosts.

However, the difference is in identity verification. In an Extended Validation (EV) certificate, the Certificate Authority or CA verifies the domain ownership, business registration and address, phone number, and other pertinent information manually. But, Domain Validated (DV) certificates verify only the registration of the website’s domain.

So, if we think about the security perspective, an Extended Validation (EV) certificate is much more secure than a Domain Validated (DV) certificate, as an EV certificate vouches for the authenticity of the website in a better way.

How to identify an Extended Validation (EV) certificate

Most of the recent browsers have an enhanced display for Extended Validation (EV) certificates. It includes :

The name of the company or entity that owns the certificate.
The name of the Certificate Authority or CA that issued the Extended Validation (EV) certificate.
Sometimes, a different color, usually green, in the address bar indicates that the browser has received a valid Extended Validation (EV) certificate.

Compatibility of EV certificates with browsers

Most of the Extended Validation (EV) certificates are compatible with the following browsers :

Microsoft Edge 12+
Google Chrome 1.0+
Internet Explorer 7.0+
Firefox 3+
Safari 3.2+
Opera 9.5+

What is Cholesky decomposition? A square matrix A is said to have Cholesky decomposition if it can be written as a product of a lower triangular matrix and its conjugate transpose. $latex A=LL^{*} $ If all the entries of A are real numbers, then the conjugate...

Tensor Hadamard Product using Python

We can use numpy nd-array to create a tensor in Python. We can use the following Python code to perform tensor addition and subtraction. import numpy A = numpy.random.randint(low=1, high=10, size=(3, 3, 3)) B = numpy.random.randint(low=1, high=10, size=(3, 3, 3)) C =...

How to create a tensor using Python?

by Amrita Mitra | October 3, 2023 | Featured, Linear Algebra | 0 Comments

What is a tensor? A tensor is a generalization of vectors and matrices. It is easily understood as a multidimensional array. For example, in machine learning, we can organize data in an m-way array and refer it as a data tensor. Data related to images, sounds, movies,...

How to combine NumPy arrays using horizontal stack?

by Amrita Mitra | October 3, 2023 | Featured, Linear Algebra | 0 Comments

We can use the hstack() function from the numpy module to combine two or more NumPy arrays horizontally. For example, we can use the following Python code to combine three NumPy arrays horizontally. import numpy A = numpy.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) B =...

How to combine NumPy arrays using vertical stack?

by Amrita Mitra | October 3, 2023 | Featured, Linear Algebra | 0 Comments

Let’s say we have two or more NumPy arrays. We can combine these NumPy arrays vertically using the vstack() function from the numpy module. For example, we can use the following Python code to combine three NumPy arrays vertically. import numpy A = numpy.array([[1, 2,...

Singular Value Decomposition (SVD) using Python
