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 ...

Symmetric encryption: uses an identical private key to encrypt and decrypt data. Examples: AES, DES, 3DES. Vulnerable to Grover's algorithm.

It is a symmetric encryption algorithm that uses keys up to 256 bits in length. It is not only fast and secure, but it’s in the public domain, just like its predecessor.

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 ...

A so-called trapdoor function typically lies at the heart of modern encryption algorithms. Trapdoor functions are mathematical operations that are easy to perform in the forward direction but much ...

The file data is then encrypted with a symmetric algorithm called as DESX. Encrypting File System (EFS) The key used for these kinds of symmetric encryption is called as File Encryption Key (or FEK).
