Message privacy, increasingly important to Bitcoiners, can be achieved with public and private key cryptography. As a Bitcoiner, you’re going to need a secure way to communicate privately, without ...

An encryption method for transmitting data that uses key pairs, comprising one private and one public key. Public key cryptography is called "asymmetric encryption" because both keys are not equal. A ...

Encryption is one of the pillars of modern-day communications. You have devices that use encryption all the time, even if you are not aware of it. There are so many applications and systems using it ...

Public key encryption has long been a cornerstone in securing digital communications, allowing messages to be encrypted with a recipient’s publicly available key while only being decrypted by the ...

In my previous article/video how does encryption work? I wrote about the principles of encryption starting with the Caesar cipher and following the development of cryptography through to the modern ...

What are cryptographic keys, and why should they be kept safe? A cryptographic key is a string of data that is used to encrypt data (to the data secret), decrypt data (to perform the reverse operation ...

In recent weeks, I’ve written about protecting data stored locally on a hard drive, against both people with physical access and potential remote attacks. But your data is much more vulnerable in ...

In our last episode of Private I, I explained the basics of public-key (PK) cryptography, a way to scramble messages in a way that only someone possessing a particular key can decrypt, without that ...

The advent of Bitcoin has revolutionized the money culture, ownership, and financial security of people. In contrast to conventional banking institutions where centralized power controls accounts, ...

The actions of certain large social networks have recently highlighted how a small number of people possess significant power over the masses and how this power is sometimes misused. Consequently, ...

Learn how to protect the information handled by your .NET applications by encrypting and decrypting the data using either a single key or a public/private key pair. Encryption transforms data into a ...
