Not sure what public and private keys are? Read our full breakdown of what they are, how they work, and how important they are today.

The mathematics underpinning the modern method of elliptic curve cryptography originated with Renaissance architect Filippo Brunelleschi ...

Post-quantum cryptography Traditional public-key cryptography algorithms will be broken easily when a quantum computer of sufficient size appears.

Why is VPN encryption important? You may have seen some VPN providers boasting about using AES-256 encryption, but it’s not immediately apparent what this means or how it helps keep your data safe.

What to expect with Quantum and the threat to encryption: We need to arm ourselves with quantum safe encryption and crypto-agility.

What’s the difference? Public key cryptography (asymmetric encryption) involves a pair of keys, while private key cryptography (symmetric encryption) uses a single shared key. Understanding the ...

Symmetric keys use the same key for encryption and decryption, while asymmetric keys use a public and private key pair. Encryption keys are used in secure communication, data storage, and privacy ...

In public key cryptography, the “public” and “private” keys work just like the first and second ingredients in this special invisible ink: One encrypts messages, the other decrypts them.
