Understanding the algorithms of ransomware is important not to replicate the attack, but to recognize the threat in time, minimize damage, and build defenses. Ransomware blocks access to data, encrypts files, and demands a ransom. In this article, we will explore their lifecycle, cryptographic principles, typical signs of infection, preventive measures, and the order of actions during an incident.

Data encryption methods help protect personal information, corporate documents, payments, correspondence, and backups from being read by unauthorized parties. In this article, we will discuss the types of encryption that exist, the differences between symmetric and asymmetric algorithms, where AES, RSA, ECC, and TLS are applied, and how to choose the right approach for a website, application, database, or device.

How to recover encrypted data is a question that arises after a ransomware attack, disk failure, password loss, or errors when working with an encrypted archive.
