How does end-to-end encryption work? End-to-end encryption works by encrypting (scrambling) data sent on one end that can only be unencrypted with a special secret number, known as a key.

Forget invisible ink, how about super-secret ink? Scientists have successfully hidden a 256-bit cipher key within molecules of ink on a handwritten letter.

As the attack surface expands and the threat landscape grows more complex, it’s time to consider whether your data protection ...

Encryption is the key Encryption has for a long time been seen as the answer for preventing threat actors being able to use data if they ever get their hands on it. Yet if the cryptographic keys ...

Public-key algorithms are important too. They help get around the fundamental drawback of symmetric-key encryption, which is that you need a secure way to share symmetric keys in the first place.

One change is that Zoom will now offer AES 256 encryption on all meetings, meaning data will be encrypted with a 256-bit key.

Though Zoom meetings already have some level of encryption, that process usually happens when Zoom's own servers generate encryption keys and distribute them to meeting participants via the Zoom app.
