Hi all,

there are dozens of tools available out there and I am not sure if I listed them all. Please add them if they're worth to mention. I am trying to find out which tools are preferable and mostly used out there. This list is focused on GPU capable tools, because using CPU only is kinda useless (except BSGS) for puzzle solving above #66. What I've found so far is:

keyhunt-cuda
- what's the main difference between keyhunt-cuda and bitcrack? both support CUDA, so what's the use case?

Bitcrack
- supports GPU, but not really multi-gpu capable as described in its readme. You need to open one window and access gpu1 on your system (first bitcrack process running), open an additional new window and run another copy of bitcrack (second bitcrack process running) and so on.
- does not support random mode

Bitcrack2
- as far as I can tell the only addition in BitCrack2 is, that you can run it in random mode. It will then search randomly through the range search space.

VanBitCrackenRandom
- was that a tool that was created and published before or after Bitcrack2, Kangaroo, etc... ? I have no idea how old and useful this tool might be and what the main differences to the other tools here presented are. Any information?

VanBitCrakcenS
- was that a tool that was created and published before or after Bitcrack2, Kangaroo, etc... ? I have no idea how old and useful this tool might be and what the main differences to the other tools here presented are. Any information?

Kangaroo
As far as I see this tool can be only used when the pubkey of an adress is known. That means that there must have been minimum one outgoing transaction from this address or a message that was signed by this address, right?

BSGS-Cuda
- runs on CPU only and cannot make use of GPU. As far as I know there is a CUDA-capable modification available, however I was not able to install and run it. Is there anyone out there who can provide a download link for the old and free version of purebasic v5.3 ? Without purebasic it's impossible to run this tool which was made by Etayson. The user was online hear about 1-2years ago for the last time, no reaction at all. Any clues?

Looking forward to hear your comments, what tool is best-suited for which purpose and case and which tools you puzzle-hunters out there are using.
