C# create aes key
WebNov 16, 2016 · First, I create a hash with SHA2 (256 bit) from the password, this hash is the key and IV in the AES Encryption. The IV can only be 128 bit, so I just cut it to the right length. You can only decrypt it if you have the password. Using the Code SecurityController.cs class code: C# Shrink WebJun 10, 2024 · You'll often generate a symmetric key and encrypt it using an asymmetric algorithm. This way you take advantage of the asymmetric algorithm to exchange the key, and you can use the speed of AES compared to RSA to encrypt the data. Plus, the symmetric key is small enough to be encrypted using RSA.
