With the rapid rise of cryptography, the RSA algorithm was a groundbreaking creation that forever changed the landscape of secure communication. Conceived in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman, RSA harnesses the computational challenge of prime number factorization to create a robust public key/private fundamental framework. This…
OCSP stapling renders it more accessible and more rapid for a customer than ever to check the status of an SSL/TLS certificate’s revocation. It is an enhancement over the existing industry standard, OCSP. But what exactly is OCSP stapling, and why does it matter for the security of your website?…
Homomorphism is an algebraic term that gives rise to the word homomorphic. “A homomorphism is a structure-preserving map between two identical algebraic structures, such as two groups, two rings, or two vector spaces.” (Wiki source) Homomorphic encryption is a kind of encryption that enables users to carry out binary operations…
Ciphers are often grouped based on their operation and how their key is applied to encryption and decryption. Block ciphers combine symbols into a fixed-size message (the block), whereas stream ciphers use a continuous stream of symbols. The same key is used for encryption and decryption when utilizing a symmetric…
The foundation of Public Key Infrastructure (PKI), which secures billions of online transactions, is the X.509 digital certificate standard. But what will happen if these certificates or the keys that go with them have an issue? They need to be revoked since it is clear that they can no longer be…
Browsers verify the validity of a website’s TLS certificate before connecting to it, and they display a warning message if the certificate has been revoked. OCSP, CRLs, OCSP must-staple, and OCSP stapling are revocations status-checking techniques browsers use. This article analyses and compares two techniques, named CRL vs OCSP. The…
If you have a website, you must have an SSL certificate. In general, you’re certainly aware of how SSL certificates work. It utilizes the Transport Layer Security (TLS) protocol to ensure that the communication between your website and the web browser (used by the user) is protected and secured. Furthermore,…
Securing Digital Communication: The Vital Role of Public Key Infrastructure (PKI) With increasing cyber threats, robust data encryption has become crucial to any organization, regardless of dimension or sector. Encryption is the process of converting plaintext into ciphertext, rendering it unreadable to unauthorized users. It plays a crucial role in…
Block ciphers and stream ciphers are the two main encryption processes in cryptography. While both ciphers serve the same purpose of data security, they vary in many important ways, making them appropriate for various uses. In this article, we will look at the differences between Block ciphers and Stream ciphers…
Hashing vs. Encryption has been a long-standing debate in the technology world. Both security measures have pros and cons, uses, and capabilities, driving a long wall of separation between them. Consider them as one-way and two-way roads. On a one-way street, you can only move in one direction, unlike a…
The advancement of information security has led to the development of numerous methods for preventing valuable information from being decrypted by attackers. Every company works with the transmission of information from a certain point to another. As a consequence, considerable effort expended to secure this data. That’s why today we…
In today’s world, where technology has taken over every aspect of our lives, it’s essential to secure our online presence. Cyberattacks are on the rise, and we are all vulnerable to them. This is where Encryption comes in. Encryption is like a secret code that only the intended recipient can…
