Hello,

I have created an updater for my application. When the application starts the user can launch an updater that will check for the latest version. Download it and copy the files to where the installation is.

Everything works fine.

However, I am looking for a more robust technique. And I have discovered it is better to hash the files on the web server with a hash algorithm and then when they have downloaded use the same hash algorithm to compare the hash values. If they are different either the files were corrupted when downloaded or some modified them without permission.

However, my problem is where do I store the hash values? I was thinking of hashing the files, and storing all the hash values for each file in a text file, and my updater will download that text file.

I am not sure if that is the best technique to use of not? Is this the normal and best way to do this?

Many thanks for any advice,
