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 ...

Nathan Eddy works as an independent filmmaker and journalist based in Berlin, specializing in architecture, business technology and healthcare IT. He is a graduate of Northwestern University’s Medill ...

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 ...

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 ...

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 ...

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

Public-key cryptography (PKC, or asymmetric cryptography) had a revolutionary effect on the theory of cryptography. PKC’s use of pure mathematical hard problems led to a study of academic, theoretical ...

The inventors of public key cryptography have won the 2015 Turing Award, just as a contentious debate kicks off in Washington over how much protection encryption should really provide. The Association ...
