Column level encryption is a type of database encryption method that allows user to select specific information or attributes to be encrypted instead of encrypting the entire database file. To understand why column level encryption is different from other encryption methods like file level encryption , disk encryption , and database encryption ...
Salting helps defend against attacks that use precomputed tables (e.g. rainbow tables), by vastly growing the size of table needed for a successful attack. [2] [3] [4] It also helps protect passwords that occur multiple times in a database, as a new salt is used for each password instance. [5] Additionally, salting does not place any burden on ...
A main encryption/decryption key is derived from user's password by PBKDF2 function. [2] Particular data binary large objects can be encrypted in a way that salt is added and/or an external user-prompted password (aka "Strong Key Protection") is required. The use of a salt is a per-implementation option – i.e. under the control of the ...
One issue that arises when using hashing for password management in the context of database encryption is the fact that a malicious user could potentially use an Input to Hash table rainbow table [31] for the specific hashing algorithm that the system uses.
PBKDF2 is for generating an encryption key from a password, and not necessarily for password authentication. PBKDF2 can be used for both if the number of output bits is less than or equal to the internal hashing algorithm used in PBKDF2, which is usually SHA-2 (up to 512 bits), or used as an encryption key to encrypt static data.

SocialDocs file encryption uses AES256 to provide a free-online file encryption tool XFire uses AES-128, AES-192 and AES 256 to encrypt usernames and passwords Certain games and engines, such as the Rockstar Advanced Game Engine used in Grand Theft Auto IV , use AES to encrypt game assets in order to deter hacking in multiplayer.
These tables compare the ability to use hardware enhanced cryptography. By using the assistance of specific hardware, the library can achieve greater speeds and/or improved security than otherwise. Smart card, SIM, HSM protocol support
The strength of Keccak derives from the intricate, multi-round permutation f that its authors developed. [5] The RC4 -redesign called Spritz refers to the sponge-construct to define the algorithm. For other examples, a sponge function can be used to build authenticated encryption with associated data (AEAD), [ 3 ] as well as password hashing ...
