Cryptography is a science and art of maintaining the security of the message which is going to be sent to the recipient so that the data or message is safe and cannot be known by other parties. Various organizations, companies, or other parties have used database technology to store and manage the data of their organizations or companies. To prevent it, an encryption method, science as well as art are necessary to maintain the files. It is also called cryptography. One of the algorithms provided by Softether in data encryption is AES128. AES128 algorithm is combined with several other encryption algorithms such as SHA and GCM. AES128 is a cryptographic algorithm that is used to secure the data. The AES algorithm uses 128, 192 and 256-bits cryptographic keys to encrypt and describe data in 128 bits blocks.
