you can see that there's an alogrithm used to generate that ... and it looks like some Hex keys .. ( the highest letter is an F)

so .. anybody tried to work on that ?!

Are they all consecutive invites, or random. (did you win them, or did you send all 6 invites to yourself all at once).
Also, hopefully, its not dependent on the time/date. Sum mechanisms use time/date along with the mechanism other than just a simple count.

yah, it looks like hex but i doubt they'd base it on anything simple... i mean, cmon, it's google...

hummm .. i found them on site ! and i took 'em like that ! :D


:D


and yeah it's google ... but you know .. it's human afterall ! so there must be an algorithm used to make that huh ?!

[Silver]

But on random invites, it hard to find out.
Its good if there was 3 continuous invites. Then, the mechanism can atleast be studied a bit.

[oblivious]

the hex will also contain information about the email you sent it to and the persons name... I'm sure they also have a date/time stamp in it too since they do expire. I don't think you will be able to crack this one so easy...

So you know the following information is contained in that string of numbers and letters:
-FIRST NAME
-LAST NAME
-EMAIL SENT TO

Potentially could contain:
-Date/Time Stamp

That's about all we know about it... I really don't think you will ever get 3 consecutive.

If this helps... I send myself 3 emails... one right after another with the same FIRST NAME, LAST NAME, and EMAIL They were sent withing 10 seconds of each other :D

*NOTE* ALL TAKEN BY HM MEMBERS... IF YOU NEED AN INVITE... PM ME!

So lets get a cracking... MORE GMAIL FOR EVERYONE!

[undacuvabruva]

oblivios, what was the name and email address they were sent to?
I might want to try altering the name by 1 letter and see how much the result differs.

This could really get interesting.

[oblivious]

hmmmmm... I'm not 100% sure. If you need me to... I can create a couple more invites. I still think it is highly unlikely that you will be able to crack it... and if you do, it probably won't work because of some safegaurd google has come pu with :D

[undacuvabruva]

nah.. i guess it would be pointless
ty anyway

HERES A GREAT IDEA GUYS!!

First People to PM me Get a Gmail Account Invite from Me.
PM me your Name and Email.
I only have 3 Invites Right Now, I will let you know when I get more So Hurry!

[oblivious]

ummmmmmmmmm....

A) There is a forum dedicated to gmail and posting invite offers
....Best way to do it is to send yourself the invites with a temporary name and then post the links on the forum (like we have done)

B) I don't think there are very many people without gmail :D Once one person on a forum gets gmail, it spreads like wildfire and everyone has one within a week :D I have seen it many times... This forum is already burned down :P

[megaman_c]

yuuuuuuuuuup .. that's what happened to me, 1 week after i got my invitation, i recieved like 20 invitations from google ! :D

i sent all of them to some friends of mine ! lo0oll

[Akallen]

I'v only got 6 so far... G-mail hates me...

[fma]

I have only got 6 so far too so.... yeah. Now i only have 3.

[Silver]

Um... maybe the first character of query string, namely 'a' in this case represents the general group of invites.
b2c4d16b29 probably contains the Email Address of the addressee, but i havent yet tried and cracked it. I am trying to though to find out.
05df28a20f-ed308d8816 -> This part i cannot understand. I mean all the part after the email. Seems like date/time stamp, or maybe, not. Maybe, it serves multiple purposes. It maybe like sum sortof a identity string, which is meant for identity of the string and the validity. Also, the same thing, maybe was randomised with the help of the date mechanism, and may also contain the date stamp inbuilt too.

[Lord Magicdka]

I have tons of gmail accounts and I STILL havent gotten any invites....I think the most I ever got at 1 time was 2 on the first account I had....

[mck9235]

Hmm magic, i have two accounts and they both got 6 invites in 3 days. LOL. Maybe google just doesnt like you. :P
