A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

Digital signatures may not be as hard to forge as previously thought. Scuttlebutt from the ponytail and Birkenstock set is that the algorithm most commonly used for creating a unique digital ...

Imagine a world where the most widely-used cryptographic methods turn out to be broken: quantum computers allow encrypted Internet data transactions to become readable by anyone who happened to be ...

It will encrypt a victim's files and then display a ransom note. Unlike most other ransomware, though, Globe uses the Blowfish encryption algorithm rather the commonly used AES encryption. Furthermore ...

When the IBM PC was new, I served as the president of the San Francisco PC User Group for three years. That’s how I met PCMag’s editorial team, who brought me on board in 1986. In the years since that ...
