Here, we will discuss how to encrypt the SQLite DB file using an AES encryption method in .NET C#, encrypting using AES symmetric encryption algorithm, which stands for Advanced Encryption Standard. Using key and IV - -initialization vector encryption will be done from the sender. From the receiver, the same key will be used and decrypted from the other end.
IV is a pseudo-random value multiple times encrypting the plain text, IV size typically 16 bytes (128 bits). AES supports different key sizes like 128 bits, 192 bits, and 256 bits. Hash key using SHA256 method example is given here.
Using Security.Cryptography library AES encryption encryption is handled, and CryptographicException is used for Exception handling. SHA256CryptoServiceProvider is used to get the hash key.
Using the FileStream class, an Encrypted SQLite DB file will be created.
