{
sha1 = HashAlgoFactory.Create<SHA1>();
random = new RNGCryptoServiceProvider ();
LastSecretGeneration = DateTime.MinValue; //in order to force the update
secret = new byte[10];
previousSecret = new byte[10];
random.GetNonZeroBytes(secret);
random.GetNonZeroBytes(previousSecret);
}示例2: TokenManager
public TokenManager()
{
sha1 = SHA1.Create();
