摘要

Data security is now a critical component in the digital age. Using cryptography, data can be protected against unauthorized access. A method known as hybrid cryptography blends symmetric and asymmetric using cryptography to increase security. In this paper, a hybrid cryptography-based secure file storage system is proposed. The file is encrypted by the system using symmetric cryptography, and the symmetric key is safeguarded using asymmetric cryptography. A symmetric key-encrypted file that the user uploads to the system can be unlocked. After that, the symmetric key is encrypted in the database using the user’s public key. The system obtains the encrypted symmetric key from the database and uses the user’s private key to decrypt the file when the user requests to access it. File is divided into N segments. Every single component of the file is encrypted using a distinct algorithm. Every file is simultaneously encrypted using a separate technique. For the purpose of decrypting files, the encryption process is reversed.
