Password hashing standards

Across the board standard for MD5?

[mcfly]

Hi all,

I'm using ASP MD5 hashing for unique non-reversible identification of pieces of software, along the lines of a licence key. ie. we can generate a key from some attribute of the software, but users can't reverse engineer the key to determine how it is generated.

Is there a standardised MD5 function which is implemented across different languages? So far all I've found in ASP is a number of 'home-made' implementations. Or am I mis-understanding this, and and MD5 gives the same resulting hash across all implementations?

Thanks for your input.

MD5 should give you identical results whoever's implementation you choose, as they should all be using the same algorithm, it may just be coded differently.
