Property Value


String that contains "SP800_108_CTR_HMAC_SHA256".


Use the string retrieved by this property to set the Key Derivation Function (KDF) name when you call the OpenAlgorithm method on the KeyDerivationAlgorithmProvider class. The string represents an Sp800-56a algorithm that uses a Hashed Message Authentication Code (HMAC) based on the SHA256 (Secure Hash Algorithm 256) message digest algorithm as the underlying pseudorandom function.

To use this KDF, you must specify the appropriate parameters by calling the BuildForSP80056a method on the KeyDerivationParameters class. The parameters are internally concatenated before the function is used by the CreateKey method to derive a key.
