Questions in the title really - I'm just curious. If I were to make a community site such as a community codebase, could I calculate the hash and integrate it to the profile here?

it's probably a simple md5 of the password, then cross-referenced by the stored md5 of the password using the username as the reference. Given the username has to be an email address it might also use the name - @email.domain

doubt there's much need for it to be much more secure than that anyway

I really doubt it has anything at all to do with the password.
If it did, then everyone's password would be publically visible - not good.

I kinda figured it was an MD5 of something (32 HEX characters) - i just cant quite see the input string. I've tried MD5 of the email (on my own account)... Doesn't seem to work.

I agree that publishing the MD5 of the password as an ID would be a little silly, although as MD5 is non-reversible then I suppose its secure enough as long as the password is mixed with another variable like email address...

I doubt it'd be the password as that can change, it's more likely to be the email address as that doesn't change, while the username does

Technically (and this might sound pedantic) the USERNAME is the email address... Kentaree you are right - the User's NAME changes, but the USERNAME is the EMAIL.

Hmmm... I'm just curious really!

Oh, and this makes it more fun, you seem to be able to change your email address for the forum aswell

ok... in that case there must be some kind of internal ID system going on. Maybe the MD5 (if that's what it is) is calculated upon registration based on a shed load of data such as registration date, email, etc. If so - it'll be impossible to work out.

why would it matter if the data can change?
although, sure you do get a 1024bit hash when you register; but somehow I doubt that it would use static data like that.

i mean if everyone is going to go on about security, then it would be better for the hash to simply be the current session md5. to me that would make the most sense, which if the case would be impossible to figure out as it'd change each time the user started a new session.

Raven - how would MD5'ing the session help?

Your profile "hash" is: 64121eaa20d2387c8616e306d30fe8ac

That is the unique ID you have on this forum. The question I was asking was how this is made, that way if I were to develop a community site I could easily link the profiles together.

It's probably generated like a GUID is, just to provide a unique identifier instead of using a standard increasing integer primary key.

The ID could then be generated from any random seed, such as the time of day and date etc.
