Property Value

Byte[]

The value that is appended to the beginning of the secret agreement during key derivation.

Remarks

This value is used for key derivation if the KeyDerivationFunction property is set to one of the following values:

• Hash

• Hmac

The value is prepended to the secret agreement, and the combined value is passed to the key derivation function (KDF) to generate the key material. By default, the value is null.
