For database driven web applications, when user signs up to your website, you may need to verify the email address of the person who signed up in your website. You may send the verification email to the person's email address with the link that he/she needs to link in order to verify the email adress.
The key has to be supplied for security reasons; for example, http://example.com/verifyemail.aspx?key=--somekeytext--
To achieve this, you need to generate random but unique keys to avoid the inconsistency and maintain the security. Here is the code to generate the unique strings. You can then store this key in the user table and match it with the key text in the verification link.
public string
GetUniqueKey()
{
string
Key = System.Guid.NewGuid().ToString();
Key = Key.Replace("-", "");
return
Key;
}
There are several other ways available. but this is the simplest way.
These are the random keys that are generated using above code.
