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 ...

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 ...

A quick hands-on guide to AES, RSA, and post-quantum encryption. Learn how they work, how to use them safely, and what to do to stay secure.

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 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 ...

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, ...

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 ...

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 ...
