Online published on 04 December, 2021. Abstract Nowadays, to Implement Communication Applications, security is quite possibly the main feature, particularly when sharing private documents. One strategy that can be utilized to get information by encoding and decoding data is Advanced Encryption Standard (AES). AES is the most widely used and best secure algorithm as it implements the encryption process very quickly during the transfer of data over the network. This algorithm is open-source cryptography that uses symmetric keys to perform encryption and decryption of documents. This algorithm is used to encrypt any media file like pictures, audio, and video. In this paper, the importance of secure communication using cryptography has been addressed, also various existing Cryptography mechanisms have discussed. The proposed system uses AES and SHA256 algorithms to perform encryption and decryption of user documents. The file is encrypted using a secret key which is given by the user and the encrypted file can be decrypted by using the same key. In this way, only authenticated users can perform decryption and restricts access to unauthenticated users. The results section illustrates the successful implementation of encryption and decryption of user documents using the secret key.
