# What are symmetric key algorithms?

### Some articles on key, keys, symmetric, algorithms, key algorithms:

Key Derivation Function - Uses of KDFs
... Key derivation functions are often used in conjunction with non-secret parameters to derive one or more keys from a common secret value (which is sometimes also referred to as "key diversification") ... Such use may prevent an attacker who obtains a derived key from learning useful information about either the input secret value or any of the other derived keys ... A KDF may also be used to ensure that derived keys have other desirable properties, such as avoiding "weak keys" in some specific encryption systems ...
Key Derivation Function
... In cryptography, a key derivation function (or KDF) derives one or more secret keys from a secret value such as a master key or other known information such as a password ... Keyed cryptographic hash functions are popular examples of pseudo-random functions used for key derivation ...
Key - Other
... Churchkey, various kinds of bottle and can openers Clef (from the French for "key"), the symbol that assigns note names to the lines and spaces of the musical staff Greek key pattern, a meander pattern Key (basketbal ...
Vector Sigma - Transformers Animated
... In Transformers Animated, the key that the AllSpark created for Sari Sumdac from her building access key resembles the key to Vector Sigma from Both Beast Machines and ...
Key Generation
... Key generation is the process of generating keys for cryptography ... A key is used to encrypt and decrypt whatever data is being encrypted/decrypted ... Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA) ...

### Famous quotes containing the word key:

They have thrown away her electric toothbrush, someone else slips
The key into the lock of her safety-deposit box
At the Crocker-Anglo Bank; her seat at the cricket matches
Is warmed by buttocks less delectable than hers.
Randall Jarrell (1914–1965)
