KeyDerivationAlgorithmNames.Sp800108CtrHmacMd5 | sp800108CtrHmacMd5 property

Applies to Windows and Windows Phone

Retrieves a string that contains "SP800_108_CTR_HMAC_MD5".

Syntax

Public Shared ReadOnly Property Sp800108CtrHmacMd5 As String

Property value

Type: String [JavaScript] | System.String [.NET] | Platform::String [C++]

String that contains "SP800_108_CTR_HMAC_MD5".

Remarks

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 Sp800-108 algorithm in counter mode that uses a Hashed Message Authentication Code based on the MD5 digest algorithm (HmacMd5) as the underlying pseudorandom function.

To use this KDF, you must specify the appropriate parameters by calling the BuildForSP800108 method on the KeyDerivationParameters before calling the CreateKey method to derive a key.
