How do I generate an encryption hash in ASP.NET MVC?

Question

I am looking into creating a custom members login system (for learning) and I haven't been able to figure out the C# command to generate an encrypted hash.

Is there a certain namespace I need to import or anything like that?

Thanks for any help.

Well, first of all an encryption hash is a contradiction. Like a vegetarian steak. You can use encryption, or you can hash them (and you should hash them), but hashing is not encryption.

Look up a class starting with Md5 ;) Or Sha1 - those are hash algoryithms. It is all there in .NET (System.Security.Cryptography namespace).

One way hashes are simpler to run and MUCH safer.

Answer 4

Using the namespace System.Security.Cryptography:

MD5 md5 = new MD5CryptoServiceProvider();
Byte[] originalBytes = ASCIIEncoding.Default.GetBytes(originalPassword);
Byte[]  encodedBytes = md5.ComputeHash(originalBytes);

return BitConverter.ToString(encodedBytes);

or FormsAuthentication.HashPasswordForStoringInConfigFile method
