  Find a text is encryted or not

  Feb 18, 2021 05:12 PM|Senthil S R|LINK

  Hi,

  i have 100 texts and some of those are encrypted. I want to know which are encrypted texts and which are plain texts. Is it possible or not? If possible, how?

  Thanks in advance.

  Hi Senthil S R,

  As far as I think,you could prefix an encrypted string with "!=!enc!=!".And then, you can simply determine whether a piece of text is encrypted or not,

  Just like this:

  private static bool IsEncrypted(string text)
  {
      if (string.IsNullOrEmpty(text)) return false;
      return text.StartsWith("!=!enc!=!", StringComparison.InvariantCulture);
  }

  More details,you could refer to below article:
