C# encrypt/decrypt password with salt

Web2 days ago · I am encrypting a file using C# implementation of the AES algorithm. I am able to encrypt and decrypt successfully the file using a well-defined couple of IV and Key arrays. I generate also the key and the IV from a password string with the SHA256 and MD5 algorithm as described here: Password as key for AES Encryption/Decryption WebThe encrypt decrypt C# string functions are in a simple class. An example project shows how simple it is to use them. Thus: Encryption of a string in C# with a password is as simple as: textBoxEncrypted.Text = Encrypt.EncryptString (textBoxString.Text, textBoxPassword.Text); Decryption is just as easy:

WebA salt is a unique, randomly generated string that is added to each password as part of the hashing process. As the salt is unique for every user, an attacker has to crack hashes one at a time using the respective salt rather than calculating a hash once and comparing it against every stored hash. WebThus, to complicate the search by the rainbow tables (databases), it is recommended to add salt (a prefix or a suffix) to the password.
