#Data encoder crypter password#
This constant determines the number of iterations for the password bytes generation function.
#Data encoder crypter code#
We divide this by 8 within the code below to get the equivalent number of bytes. This constant is used to determine the keysize of the encryption algorithm in bits. If you require something more complex, and which offers authenticated encryption, check out this post for an implementation. For example, if your "receiver" of an encrypted string is receiving the string directly from a trusted "sender", then authentication may not even be necessary.

Without knowing your exact requirements, it's difficult to say whether the code here is sufficiently secure for your needs, however, it has been produced to deliver a good balance between relative simplicity of implementation vs "quality". recipient knows message was sent by the sender). message is unknown to 3rd parties), whilst authenticated encryption aims to provide both privacy and authenticity (i.e. Encryption alone provides only privacy (i.e. (Note this is an improvement of the first version's use of the older PBKDF1 algorithm).įinally, it's important to note that this is still unauthenticated encryption. The "strength" of using this comes from using the RijndaelManaged class to perform the encryption for you, along with using the Rfc2898DeriveBytes function of the namespace which will generate your encryption key using a standard and secure algorithm (specifically, PBKDF2) based upon the string-based password you supply. The result of this is that encrypting the exact same plaintext with the exact same password gives and entirely different ciphertext result each time. Since salt and IV must be the same between the encryption and decryption of a given string, the salt and IV is prepended to the cipher text upon encryption and extracted from it again in order to perform the decryption. Unlike the first version of this code, which used the exact same salt and IV values every time, this newer version will generate random salt and IV values each time. Of course, there's an equivalent method to decrypt the encrypted string with the same password. The following class is one I wrote a while ago to perform exactly the kind of thing you're after, a simple single method call to allow some string-based plaintext to be encrypted with a string-based password, with the resulting encrypted string also being represented as a string. but this is precisely the kind of detail that can be somewhat abstracted away within your "wrapper" class.

The RijndaelManaged class does indeed normally require you to "muck about" with byte arrays, salts, keys, initialization vectors etc. Rijndael is the algorithmic name of the current Advanced Encryption Standard, so you're certainly using an algorithm that could be considered "best practice". You can, however, "roll your own" wrapper class around something like the built-in RijndaelManaged cryptography class. See the end of the post for a list of specific improvements.Īs other people have said, Cryptography is not simple so it's best to avoid "rolling your own" encryption algorithm.

UPDATE 23/Dec/2015: Since this answer seems to be getting a lot of upvotes, I've updated it to fix silly bugs and to generally improve the code based upon comments and feedback.
