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 ...

Encryption is essential for protecting data, with both symmetric and asymmetric methods offering unique advantages.

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.

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

Software like BitLocker, for example, uses the AES encryption algorithm with 128 or 256-bit keys, making it a great choice for those that value security and privacy.

SIKE was a contender for post-quantum-computing encryption. It took researchers an hour and a single PC to break it.

Encryption secures digital data by encoding it mathematically so that it can only be read, or decrypted, with the correct key or password.

Using public key cryptography, Alice sends her message to Bob and encrypts it using his public key. Anyone can intercept the message, but only Bob can decrypt it using his private key.

Researchers identified a problem that holds the key to whether all encryption can be broken -- as well as a surprising connection to a mathematical concept that aims to define and measure randomness.
