I am searching for this tool for a long time, however I cannot find it, can someone please help me where it is? Thank you.
No. As far as I know, the Windows Vista/7 method has never been deciphered. That's why even sanity-testing Windows 7 keys takes a long time per key, compared to Windows 8 and beyond.
No, that takes a long time because the crypto is time-consuming*, and reimplementing the validation won't magically make the process faster. If you are sufficiently good at code optimization; if you have libraries like GMP/MPIR with their hand-optimized assembly code at your disposal; then you might beat MS's pidgenx.dll (it is not particularly picky with bignum primitives and is further slowed down by the obfuscation) by maybe 10%**. Definitely not 10 times. And if you're okay with the MS checker, there are plenty of tools already. * without knowing the encoded data. The validation basically bruteforces the encoded data; once you got internal results of a successful validation, you can re-validate much faster. In particular, MS activation servers don't waste their time because the activation request contains not only the product key, but also the data encoded in that key. ** an estimate, I haven't actually tried, SageMath definitely won't cut it in terms of speed, and it's too much work otherwise
Well, yes, but... Wouldn't that be kinda beating a dead horse at this point? NT 6.0 and 6.1 are on their last support phase, and any result would be purely educational. My wild guess is that product keys will go away completely, eventually.
But still it would be cool to crack the pkey algorithm, for educational purpose. Then we can achieve many things like slp activation of all edition (albeit with fake serial). Out of support dont really matter that much, for example telephone activation for xp was cracked too many years after end of support. And even if NT 6.0/1 was in support, the tool wont be very practical due to secret embedded in the keys.
For why you need this ? For activation use KMS_vl_all or ezwindslic uefi or windows loader for csm aka legacy mbr Or massgravel for windows 10 and 11 any edition For office you have serial key up to office 2007 / 2010 up to 2024 kms or massgrave ( ohook ) and for office 365 use ohook are recommanded Keyinfo are useless and for check if key Are geniune better are pidgenX and variant Only product of microsoft you cannot activate are windows 8.0 embedded standard To fix shutdown , just disable 1 service to fix this And server azure core aka datacenter azure sku are bad outside azure subscription ( hotpatch not works fines... )
