We were sent this formula to encrypt a string written in Java:

String        myInput = "test1234";
MessageDigest      md = MessageDigest.getInstance("SHA");
byte[]            myD = md.digest(myInput.getBytes());
BASE64Encoder    en64 = new BASE64Encoder();
String       myOutput = new String ( 
                            Java.net.URLEncoder.encode( en64.encode(myD)));
// myOutput becomes "F009U%2Bx99bVTGwS3cQdHf%2BJcpCo%3D"

Our attempt at writing this in C# is:

System.Security.Cryptography.SHA1 sha1 = 
    new System.Security.Cryptography.SHA1CryptoServiceProvider();
string myOutput = HttpUtility.UrlEncode( 
                      Convert.ToBase64String( 
                          sha1.ComputeHash( 
                              ASCIIEncoding.Default.GetBytes(myInput))));

However the output is no where near the same. It doesn't even have percent signs in it. Any chance anyone would know where we are going wrong?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
