encryption

In an era where data breaches and cyber threats are commonplace, understanding data encryption is crucial for protecting sensitive information. Data encryption transforms readable data (plaintext) into an unreadable format (ciphertext) using mathematical algorithms and keys, ensuring that only...

Hardware Security Modules (HSMs) are specialized devices designed to securely store cryptographic keys, perform cryptographic operations, and protect data in accordance with high security standards, including PCI DSS (Payment Card Industry Data Security Standard). Using HSMs for encryption is an...

Implementing encryption in accordance with the Payment Card Industry Data Security Standard (PCI DSS) is a key element to protect cardholder data (e.g. card number, name, expiration date) at rest and in transit. PCI DSS (version 4.0 as of August 2025) sets strict encryption requirements to...

Almost a year ago I wrote an article about post-quantum cryptography and in this article I decided to continue this topic, since every year the moment approaches when cryptography as we know it today will go under. With the advent of quantum computing, interest in asymmetric encryption...

Progress is unstoppable, but there are still unanswered questions. Recent media reports that Chinese scientists have broken "military encryption" using quantum computers have sparked widespread speculation about the future of cybersecurity. However, a detailed analysis showed that such claims...

Digital thieves are celebrating their victory over a new security feature. Developers of popular infostealers have told customers that they have learned how to bypass Chrome's App-Bound Encryption feature and collect authentication cookies that were previously returned encrypted. A new...

The EU authorities expressed their intentions to disclose correspondence in messengers. Danish Justice Minister Peter Hummelgaard proposed to restrict access to WhatsApp, Telegram and Signal messengers, as they are used by criminals to coordinate their activities. Hummelgaard said that existing...

New algorithms bring us closer to the moment of truth in the digital world. Modern encryption methods, such as RSA, are based on the fact that even the most powerful classical computers are not able to quickly decompose a large number into prime factors. However, quantum computers promise to...

NIST releases the world's first post-quantum encryption standards. The US National Institute of Standards and Technology (NIST) has approved three new encryption standards designed to protect information from threats related to the development of quantum computers. The standards were developed...

Cloud services will revolutionize privacy. Apple introduced a new package for homomorphic encryption in the Swift programming language. This package, which is publicly available, allows you to perform calculations on encrypted data without having to decrypt it. This solution provides a high...

British police have shut down a network of phone scammers. UK law enforcement agencies have announced the closure of the Russian Coms platform, which was used by hundreds of scammers to deceive victims around the world. The platform, which was launched in 2021, resulted in tens of millions of...

CVE-2024-27198 opened a compromise portal for hackers. When will the administrators close it? Attackers continue to actively exploit vulnerabilities in the JetBrains TeamCity software, deploying ransomware, cryptocurrency miners, Cobalt Strike beacons, and Spark RAT remote access Trojans. The...

You can't intercept it now, you can't decrypt it later: Tuta has introduced a new super-secure protocol. German company Tuta, developer of the secure email service Tuta Mail with more than 10 million users, has introduced a new quantum-resistant encryption protocol — TutaCrypt. The development...

Are the authorities fighting for the safety of children or are they afraid of losing access to user data? Nevada authorities are taking drastic steps against Meta, demanding that minors restrict access to encrypted messages in the Messenger app. The initiative of the State of Nevada is aimed at...

The Strasbourg Court has defended the right of ordinary citizens to privacy of correspondence. A recent decision by the European Court of Human Rights (ECHR) called into question laws requiring weaker encryption and longer data retention times, such as those promoted by the European Chat...

Fully homomorphic encryption allows you to process data without revealing its contents. In the world of computer security, a breakthrough is being planned thanks to fully homomorphic encryption (FHE) technology, which allows programs to work with encrypted data without decrypting it. The...

US Senator Lindsey Graham has introduced the Eliminating Abusive and Rampant Neglect of Interactive Technologies Act, which allows law enforcement and tech companies to work together to protect children. The bill applies to any company offering "interactive computing services", including...

End-to-end encryption What is end-to-end encryption and what other options are there End-to-end encryption is when messages are encrypted on your device and decrypted only on the device of your interlocutor (in English, this is called end-to-end, which can be translated into Russian as "from...

Anonymity of I2P network participants is achieved by using tunnels. An important feature of I2P is that only the person who created it knows the length of the tunnel, its beginning and end. Each node of the network has its own incoming and outgoing tunnels, and by default it also acts as a...

When people talk about crypt in general, there are some fundamental principles. One of them is the Kerkhoffs principle, which says that open source is very important in cryptography. More specifically, it provides general knowledge about the protocol design. The point is very simple: the...
