Происходи ошибка:
System.Security.Cryptography.CryptographicException: Error occurred during a cryptographic operation.
в CryptoApiHelper.SignValue(SafeProvHandleImpl providerHandle, SafeHashHandleImpl hashHandle, Int32 keyNumber, Byte[] hashValue)
Конкретно при вычислении размера подписи, в этом кусочке:

        if (!CryptoApi.CryptSignHash(hashHandle, (uint)keyNumber, null, 0, null, ref signatureLength))
        {
            throw CreateWin32Error();
        }

Часто повторяется, в чем может быть проблема?
