Data security has emerged as a major challenge. Many techniques and procedures have been developed in order to reach a level of security like data encryption, data backup, data masking, etc., which may require high initial costs and maintenance. Also, once sensitive data has been masked, it cannot be changed back to its original form. Cryptography can be used for data security by data encryption and decryption. One can quickly discover the existence of concealed information in carrier files by employing cryptography. The strategy used in this project utilizes cryptographic methods. In cryptography, the proposed method uses AES algorithm. This helps to maintain the data in a secure way. Cryptography is used to conceal the data in any text file document by utilizing the AES technique. This ensures that no other network user can access the information that is protected. The original message can only be viewed by the sender and can be exchanged with the recipient with the help of a key which is used to encrypt and decrypt the data. The method uses three types of AES algorithms namely AES-128, AES -192 and AES-256. AES-256 is taken as the most efficient one when compared to other two algorithms. This study offers an ASCII-based cryptography technique as a solution to data security.
