A brief guide on how to create encrypted containers in Linux using Cryptsetup, giving you tools for keeping your most important files and data protected.
There are a lot of cloud services that tout encryption strength as a measure of how well they guard your data. It is quoted in bits, which is the
size of the key. So you see services quoting 128 bit, 256 bit or even
2048 bit.
Being concerned with the security of online communication and information exchange is absolutely OK. It is a reflection of the fact that you
are aware of global surveillance happening every second of our presence online. Our online activities are monitored, intercepted, collected, and stored. And now imagine that what you know is only the small fraction of what is really happening with our information.
Imagine, you are messaging your business partner about a super secret idea, it is worth $ 1m, will you trust the messaging application not to read your super secret conversation? No, right. No one will, still people across the world use whatsapp for such sensitive messaging (although I prefer telegram for my secret conversations). Well, turns out, it is because most messaging apps(including whatsapp) use a technique called End to End Encryption, which doesn’t allow these messaging services or their employees to read your conversations with your contacts. But how does this works, well, that is what we will try to understand here.
Organizations nowadays are storing and performing computation of the data on the cloud instead of handling themselves. Cloud Service Providers (CSPs) provide these services at an affordable cost and low maintenance. But to ensure compliance and retain privacy, organizations need to transfer the data in an encrypted format, which does ensure the confidentiality of the data. However, once the data reaches the cloud, the CSP has to decrypt the data to perform operation or computation.
In 2019 our devices know us better than close friends and relatives. Browsers, messengers, social media trackers analyse the actions you do online and your interactions with content to expand their manipulation. The history of browsing is used to target ads and create more triggering banners for you exclusively. These technological advancements might look smart and comfortable, but the invasion of privacy has gone too far.

Keeping information secured and protecting the integrity of data over the internet is now becoming a huge and complex task, due to the increasing number of threats to the information security.
You hear the sound of an alarm clock. The first thing you see after you wake up is a notification. The entire user base of your WordPress* app has leaked into Darknet. According to GDPR, you’re both data controller and processor so now you’re facing a number of fines and court hearings. Not fun at all.
We use passwords to access personal information and user accounts. With so many applications requiring passwords (e.g. online banking, shopping and social media just to name a few), it can be hard to track and at worst remember. Some applications require users to change their passwords every so often, and that can lead to users forgetting them or getting careless by writing down their password on a piece of paper. That piece of paper can later be misplaced which can lead to worse things. The problem with requiring frequent password changes and applying complexity to passwords is that it can become more complicated for users.
The 21st century is the age of technology and the Internet. Today, the whole world is online. We are increasingly moving all our business to the Internet space. It is the place where we work, communicate, order food, pay for purchases, watch movies and listen to music.

Now, it’s the age of information society and data has replaced petrol as the economy’s driving force. The reason is that with the help of Big Data, people significantly improve production efficiency and business economics. That’s true.
With two recent vulnerabilities making headlines this month, notably CVE-2019-14899, impacting VPNs running on Linux distros and Atlassian’s zero-day flaw reported by SwiftOnSecurity concerning leak of private keys, it should be no surprise anymore as to why encryption merely breeds a feeling of security rather than guaranteeing it.
The Second World War brought to the front burner the world of espionage, which is the precursor of cybersecurity, as is seen in the modern world. Technological advancements such as the quantum computer necessitate that we take the war against cybercrimes to another level.
Encryption makes the digital world work. It consists of a few elegant math equations that scramble data before being sent over the internet where prying eyes could otherwise intercept it, read it, and manipulate it. Encryption is the reason everything from financial transactions to state secrets get passed around the internet nearly instantaneously, unlocking massive amounts of innovation, wealth, and prosperity as a result.
Complacency with privacy invasion has become our 6th sense. Handing over the intimate details of our lives to corporate and government stooges has become a virtue and civic duty. It should come as no surprise that, even for a society dripping with tech-savviness, the average person would rather their government act than to take action themselves. According to Pew Research:
