GostSharedSecretAlgorithm	Распределенный секрет.

Overrides

Gost3410Algorithm.CreateAgree(Gost3410Parameters)

Dispose(bool)

Освобождает неуправляемые объектом класса Gost3410EphemeralCryptoServiceProvider ресурсы и, по выбору, управляемые.

Declaration

protected override void Dispose(bool disposing)

Parameters

Type	Name	Description
bool	disposing	true, чтобы освободить и управляемые, и неупавляемые ресурсы; false, чтобы освободить только неуправляемые.

Overrides
