What is public key infrastructure and how does it works?

Hello my dear friends! How are you doing? Today we are going to discuss about public key infrastructure. Let's discuss about what is public key infrastructure and how does it work. Public key infrastructure is something connect with computer security. It ensures and helps for computer security. Firstly let's see what is public key infrastructure? Public key infrastructure is a set of hardware, software, people, policies and procedures needed to create, manage, distribute, use, store and revoke digital certificates. PKI directly connect with cryptography.…

Asymmetric Key Encryption

Hello friends! Today we are going to look at asymmetric key encryption. So far we were talking about many security topics. If you are newbie for cryptography please go through our introduction to cryptography concepts post. You can learn the basics of encryption. https://youtu.be/AxD5Vt8AX0o What is symmetric key encryption What is asymmetric key encryption? asymmetric encryption is also known as the public key encryption. The meaning of asymmetric means two things, not same. In asymmetric key encryption we use two keys for the encryption.…

Symmetric Key Encryption

Hello dear friends! How are doing I hope all of you are fine. Today I have brough you another information system security post. So far we have discussed about many system security details. If you can remember we firstly had a brief intro to encryption. Then secondly we learned about different ciphers. As per that we discussed ciphers can be divided into types. They are block ciphers and stream ciphers or substitution ciphers or transpositions. We do the encryption based on any method above.…

Types of Ciphers for encryption

Hello dear friends! how are you? I hope all of you are doing well. Today we are going to discuss another information system security post. So the topic we are going to discuss is the types of ciphers for encryption. I hope all of you have a sound of knowledge about encryption. If you don't have a basic knowledge about key concepts of encryption, please visit our introduction to cryptography article. Introduction to Ciphers Let's have a brief introduction about ciphers first. The encryption…

Introduction to cryptography concepts

Hello dear friends! How are you doing? Hope everyone is fine these days. Today I am hoping to discuss another interesting topic. This is a topic which is never been discussed in the myexamnote until now. Although from today onwards I hope to write more articles about this. So let’s see what is the topic for today. So today’s topic is an introduction to cryptography concepts. Firstly let’s see what kind of thing today we are going to talk about? We are going to…
