Webb29 aug. 2024 · In short, AES is a symmetric type of encryption, as it uses the same key to both encrypt and decrypt data. It also uses the SPN (substitution permutation network) algorithm, applying multiple rounds to encrypt data. These encryption rounds are the reason behind the impenetrability of AES, as there are far too many rounds to break … Webb18 nov. 2024 · C# Aes aes = Aes.Create (); CryptoStream cryptStream = new CryptoStream ( fileStream, aes.CreateDecryptor (key, iv), CryptoStreamMode.Read); The following example shows the entire process of creating a stream, decrypting the stream, reading from the stream, and closing the streams.
