Abstract

In our daily lives, passwords are the primary form of authentication on various web applications and stored in a hashed format in the database. Password security only using hashing algorithms is cracked with password cracking attacks like Brute force attack, Dictionary attack, and Rainbow Tables. In our research project, we have developed a hybrid model, where the password is hashed with Argon2i hashing and encrypted using AES encryption scheme to provide strong security against brute force attacks. To increase the security level of the encryption key, we have derived the crypt-key from PBKDF2 and hashed it again using SHA-256. The performance of our proposed model has outperformed existing hybrid approaches like Bcrypt with AES and Scrypt with AES in terms of Encryption time, Decryption time, and Throughput.
