Can you please tell your configuration for 1080ti? (b, t, p and any other relevant info). What CUDA do you use? (9.2 or the newest 10.1).
I tried on the week to test 1080ti (Gigabyte Gaming OC 11Gb) and received thr result 150 Mkey/sec (as another guy posted earlier) with -b 56 -t 512 -p 2048.

I've not tried running BitCrack with newer GPU's, i have 3 older ones running, but they are tweaked to the max of their capacity.

I have not seen any significant performance issues running CUDA 9.xx vs. 10.xx, i know that there is more features in some particular BitCrack builds running CUDA 10.xx

I've looked up your 1080i specs, and according to those i would try and run with any these settings:

-b 88 -t 448 -p 2048
-b 176 -t 672 -p 2048

if you encounter a crash or a message displaying your GPU is out of memory, you need to tweak the -p parameter to a lower value, let us know how this turns out Wink

And if this is running just fine, you might as well add more value to -p as this GPU has a lot of memory

It is possible that some private keys to be "outside" of the standard agreed key space? Somewhere where nobody will search?

That won't work. A key value outside the curve literally means that it's invalid (presumably, the public key cannot be computed from such a private key). Once you go above the maximum value, the key will either be rejected (if the software checks), or the value will overflow back to the start of valid key space.

Your post is very informative, but goes down in history, maybe you should create a separate topic?

This "another" key works as well. Try to check it in bitcoin address generator, or try to import this file into your wallet. You will receive the access to the same address of wallet #62 lol )

Maximum value for secp256k1 is:

FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE6 AF48A03B BFD25E8C D0364141

Your key is above this value:

FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE6 AF48A03B F60FB2AB 8647ED2F

Some software will correctly reject this out of range value, but others will just overflow and wrap max+1 to 0.

The result of F60FB2AB 8647ED2F minus BFD25E8C D0364141 is 363D541E B611ABEE, which is the "proper" key. That's why your key works: when wrapped around it ends up being the same calculated value.

(If this was a clever joke, sorry that I spoiled it.

It turns out the transition to the second round (to a new ring)?

This private key does not appear to be on the ECDSA curve

Yeah I know vanitygen has been around a while but I found another vanity program called vanitysearch that is 10 times faster than vanitygen and 3 times as fast as bitcrack, at least it is with my 1080ti!

https://github.com/JeanLucPons/VanitySearch

This one ( VanitySearch.exe 1.15 ) is infected with a virus.

Ah crap is it? what virus?

Edit: I just scanned it with kaspersky online and it said no threats found, also my windows defender didn't pick anything up?

Edit 2: Zielar already found it lol https://github.com/JeanLucPons/VanitySearch/issues/23

SecureAge APEX - Malicious
Sophos ML - Heuristic

As almightyruler said, it's probably just picking up on the fact that it's essentially a modified crypto miner, but can you provide more details? I have it running on my main PC and I don't want any viruses

hey has anyone checked out vanitysearch?

With vanitygen I get 100MKey/s, with cubitcrack I get 350Mkey/s but with vanitysearch I get 1000Mkey/s and that's on a 1080ti

Vanitysearch has a starting point parameter but no end point parameter but I reckon the code could be altered for keyspace parameters

can u show me example bat command?

Could be a false positive, since searching for vanity addresses is similar to proof-of-work mining. It may be detected as mining malware.

I've seen some coin clients that I compiled myself -- on a NON Windows system -- throw up antivirus warnings...
