Question

talk about database encryption and what type of encryption for database

Answer 1

Data is the most valuable asset in this century. And this data is stored in databases. And database must be secured very well. To do this we encrypt the data inside the database using encryption algorithms. This is called database encryption. The data is changed from readable forms to cipher text using algorithms. There are various types of encryptions used but mostly these are:-

• 3DES:- Triple Data Encryption Standard. It encrypts the data 3 times and make it secure. So security is very high as a hacker has to break thecode 3 times. It is a symmetric key block cipher.But being encrypted 3 times, the data becomes slow to access.
• AES:-Advanced Encyption Standard:- It is a block cipher technique where each block length can be 128,192 or 256 bits. Data is encrypted and the key is shared directly using other
• RSA:- Rivest-Shamir-Adleman. In this method 2 keys are generated called public key and private key. Data is encrypted using public key and decrypted by private key.

There are various other algorithms too but mostly these are used.
