Is there a .Net 1.1 compatible String.GetHashCode implemented in .NET 2.0 code?

I have an existing application in which I made a mistake using String.GetHashCode and saving it to disk. Now, when I upgrade the application to .Net 2.0, I find that this solution has returned to bite me in the butt.

I am interested to know if anyone knows about the .NET implementation of the .NET compatible string hashing algorithm.

Obviously, the best solution would be to buy a time machine and go back to 2002, as well as hit yourself in the shin even to use the hash code in this way. Since this does not seem likely, I am looking for a workaround. I have existing users with this data in my systems, so I am not able to do one big hash conversion or something like that.

When changing to 2.0, I will update the code so that of course it uses MD5 or SHA.

I considered extracting the String.GetHashCode source from Mono, but since Mono is the GPL and my application is commercial, this is really not an option. I don’t even know if the Mono implementation is compatible with the MS.Net implementation, since the contract for GetHashCode does not require it to be compatible.

Any ideas?

You're not the only one it seems: Getting the .NET 1.1 CLR String Hash Codes in the .NET 2.0 CLR

Link to BackCompatibleStringComparer , which (supposedly, I can not check) shows the implementation of the old GetHashCode().
