Encryption is the process of converting data into a form that is unreadable by unauthorized parties. This is done by using a mathematical algorithm to scramble the data, and then using a key to unscramble it. The key is a piece of information that is known only to the sender and receiver of the encrypted data.
Decryption is the process of converting encrypted data back into its original form. This is done by using the same mathematical algorithm and key that were used to encrypt the data.
This tutorial shows how to use OpenSSL in Linux systems (Kali in the video) for symmetric and asymmetric encryption and decryption. OpenSSL is a free and open-source toolkit that provides a robust, commercial-grade, full-featured toolkit for general-purpose cryptography and secure communication. Internet servers, including most HTTPS websites, widely use it. […]
Tcpcrypt is a protocol that attempts to encrypt (almost) all of your network traffic. Unlike other security mechanisms, Tcpcrypt works out of the box: it requires no configuration, no changes to applications, and your network connections will continue to work even if the remote end does not support Tcpcrypt, in […]
OpenSSL, bir açık kaynaklı sertifika yönetimini ve güvenlik protokollerini (özellikle SSL/TLS) destekleyen bir kütüphanedir. Bu kütüphane, birçok farklı işletim sisteminde kullanılabilir ve genellikle ağ güvenliği ile ilgili çeşitli görevleri yerine getirmek için kullanılır. Örneğin, OpenSSL, bir web sunucusu veya bir istemci arasında güvenli bir iletişim kurulmasını sağlamak için kullanılabilir. OpenSSL, […]
By using math and cryptography, Blockchain is challenging the status quo in a radical way. Will governments and financial institutions embrace it?
