I want to generate a hash code for a file. Using C# I would do something like this then store the value in a database.

byte[] b = File.ReadAllBytes(@"C:\image.jpg");
string hash = ComputeHash(b);

Now, if i use say a Java program that implements the same hashing alogorithm (Md5), can i expect the hash values to be the equal to the value generated in C#? What if i execute the java program from different environments, Windows, Linux or Mac?

Is hashing of just "username + password" as safe as salted hashing

as seen on Programmers - Search for 'Programmers'
I want to hash "user + password". EDIT: prehashing "user" would be an improvement, so my question is also for hashing "hash(user) + password". If cross-site same user is a problem then the hashing changed to hashing "hash(serviceName + user) + password" From what I read about salted hash, using… >>> More

It is currently said that MD5 is partially unsafe. Taking this into consideration, I'd like to know which mechanism to use for password protection. Is “double hashing” a password less secure than just hashing it once? Suggests that hashing multiple times may be a good idea. How to implement password… >>> More

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
