Secure Sockets Layer (SSL) is a cryptographic protocol used to secure internet communications. SSL encrypts data that is transmitted between a client and a server. This makes it possible to protect sensitive data, such as passwords and credit card numbers, from being intercepted by third parties.
OpenSSL is a free and open-source implementation of the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols.
OpenSSL, the open-source cryptographic library, has released its 3.2 version in beta, introducing several new features and improvements. This update brings initial client-side support for QUIC, a transport layer network protocol developed by Google and adopted by the IETF. Future versions, OpenSSL 3.3 and 3.4, are set to refine this […]
The article from IoT For All delves into the importance of ensuring the security of IoT devices, especially with the increasing migration of systems and services to the cloud. The piece provides a comprehensive overview of strategies to bolster MQTT infrastructure system security from various angles. Here are the key […]
Demonstration of using OpenSSL to create RSA public/private key pair, sign and encrypt messages using those keys, and then decrypt and verify the received messages. Commands used: OpenSSL. Created by Steven Gordon on 7 March 2012 at Sirindhorn International Institute of Technology, Thammasat University, Thailand. Using the RSA algorithm, RSA […]
OpenSSL 1.1.1, launched in 2018 as a Long Term Support (LTS) version of the open-source secure communication library, has reached its end of life. This means users must transition to a newer version unless they are willing to pay for extended support. For those not prepared to shift to the […]
The change in OpenSSL’s licensing to the Apache License v2 (often referred to as ALv2) has several implications for businesses and developers. Here’s a breakdown: Permissive Licensing: The Apache License v2 is a permissive open-source license. This means that the software can be freely used, modified, and distributed, even in […]
The OpenSSL migration guide provides details on the changes required to migrate to new versions of OpenSSL, specifically covering OpenSSL 3.0 & 3.1. Some of the main changes include: Further details can be found in the original documentation.
SSL (Secure Sockets Layer) bir güvenlik protokolüdür ve internet üzerinde veri iletimini şifreleyerek güvenli hale getirir. SSL, web tarama ve e-posta gibi internet üzerinden veri iletimi yapılan uygulamalar için kullanılır ve verilerin güvenli bir şekilde iletimini sağlar. SSL, bir sunucu ve bir istemci arasında bir bağlantı kurulurken kullanılır ve bu […]
Demonstration of using OpenSSL to create RSA public/private key pair, sign and encrypt messages using those keys, and then decrypt and verify the received messages. Commands used: OpenSSL. Encryption And Decryption Encryption is converting data into an unreadable form by unauthorized parties. This is done by using a mathematical algorithm […]
In this video, we will learn how to generate an SSL/TLS certificate signing request (CSR) and have it signed by a Certificate Authority (CA). We won’t submit the CSR to a real CA for this tutorial. Instead, we will play both the certificate authority and the certificate applicant. We will […]
Onion Architecture, or Hexagonal Architecture, is a software design pattern separating an application’s core logic from the surrounding infrastructure. It is designed to create a flexible and decoupled architecture that is easy to test and maintain. The Onion Architecture is a software development approach commonly associated with Domain-Driven Design (DDD). […]
