(Unlike asymmetric encryption algorithms, which use two different keys.)Įncryption algorithms, in general, are based in mathematics and can range from very simple to very complex processes depending on their design. Symmetric encryption algorithms use the same encryption key for both encryption and decryption. Convert the ciphertext back to plaintext. Convert readable text (plaintext) into unreadable, encrypted text (ciphertext). Symmetric encryption algorithms are used (combined with an encryption key) to do two main things: They’re a set of instructions or steps that computers follow to perform specific tasks relating to encrypting and decrypting data.įeel like you need a universal translator? Okay, let’s break this down a bit more. Symmetric algorithms are the cryptographic functions that are central to symmetric key encryption. What Is a Symmetric Algorithm and How Does It Work?
#You must supply the bulk decryption key lotus notes series
We’re about to take a deep dive into exploring what symmetric encryption algorithms are, why they’re important, and what the most common symmetric encryption algorithm types are.Įditor’s Note: This article is the first in a series of articles on symmetric encryption.
Make sure to refresh your coffee (or earl grey tea, if that’s more your speed). Damn it, Jim, I’m a cybersecurity writer, not a cryptographer.) While fascinating, symmetric key algorithms aren’t exactly “light” or easy reading - so I’ve got to have some fun when writing. (Yes, I know, I’m really flying my nerd flag high today. They’re integral to information security and are what help your business move forward with data encryption securely and at faster-than-light speeds. If you were to put it into Star Trek-related terms, symmetric algorithms are the warp drive for your starship’s propulsion system. Symmetric encryption algorithms are the underlying processes that make secure communications possible. We’ll explore symmetric key algorithms and take you to places no non-IT person has gone before In Beyond Hashed Out, Everything Encryption, ssl certificates Much like tribbles in Star Trek, symmetric encryption is everywhere.
