Encryption is commonly used to secure online banking sessions and to protect credit-card data. But for the average computer user, it remains a mystery.

Full disk encryption, also known as whole disk encryption, protects data that's at rest on a computer or phone, as opposed to email and instant messaging data that's in transit across a network.

Nearly. Since encryption is just a really complex equation, theoretically it can be broken by a powerful enough computer, given enough time.

In an era where cyber threats are ever-evolving, ensuring the security of our data is paramount. From quantum-resistant ...

Using side-channel technology, researchers at Tel Aviv University can extract decryption keys from RSA and ElGamal implementations without altering or having control of a computer.

Active Cypher built a mini-quantum computer (repurposed hardware running quantum algorithms) to prove that conventional encryption (RSA + AES) is nearing ...

The more immediate impact of a medium-scale quantum computer is the threat it — and those that come after it — will pose to how we all use encryption today.
