Get a SHA1 hash of a string

public static byte[] GetHash(string inputString)
{
	HashAlgorithm algorithm = SHA1.Create();  // SHA1.Create()
	return algorithm.ComputeHash(Encoding.UTF8.GetBytes(inputString));
}
 
public static string GetHashString(string inputString)
{
	StringBuilder sb = new StringBuilder();
	foreach (byte b in GetHash(inputString))
		sb.Append(b.ToString("X2"));
 
	return sb.ToString();
