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 ...

Ever since writing has existed, people have wanted to send secret messages to one another--and others have wanted to intercept and read them. This is the third installment of the blog series taking ...

For the first time, researchers have demonstrated that a large portion of cryptographic keys used to protect data in computer-to-server SSH traffic are vulnerable to complete compromise when naturally ...

Czech academics have detailed this week a new cryptographic attack that can recover private keys used to sign operations on some smart cards and cryptographic libraries. Once obtained, the private key ...

In 1994, the computer scientist Peter Shor discovered that if quantum computers were ever invented, they would decimate much of the infrastructure used to protect information shared online. That ...

As a Bitcoiner, you’re going to need a secure way to communicate privately, without relying on a company to encrypt your data for you. For example, freely available methods with end-to-end encryption ...
