MD5 Hash a String to a Base64, Hex, or URL-Encoded String

Download: Chilkat .NET Assemblies

C# code showing how to MD5 hash a string returning the result as an encoded string.

	// Create an instance of the Chilkat encryption class.
	Chilkat.Crypt2 crypt = new Chilkat.Crypt2(); 

	// Any code begins the 30-day trial.
	crypt.UnlockComponent("30-day-trial"); 

	// Set the hashing algorithm
	crypt.HashAlgorithm = "md5"; 

	// Indicate that we want Base-64 output.
	crypt.EncodingMode = "base64";

	string inputString = "This string is to be hashed.";

	string hashStr = crypt.HashStringENC(inputString);
	MessageBox.Show(hashStr);

	// Return the hash as a hexidecimalized string.
	crypt.EncodingMode = "hex";
	hashStr = crypt.HashStringENC(inputString);
	MessageBox.Show(hashStr);

	// Return the hash as a URL-Encoded string.
	crypt.EncodingMode = "url";
	hashStr = crypt.HashStringENC(inputString);
	MessageBox.Show(hashStr);
