Why would you want to search random key space?

Someone mentioned in this topic(OP?) that there is a possibility, but I have not found..
At first glance, a random start in a given range seems more promising than a long straight road.
Something like Vanitygen, where the number changes every 1000000 passed keys

Why not add the ability to search by ripemd160 [...] to speed up

ripemd160(base16) <--> btcaddr(base58) <--> Int/Dec(base10) <--> Hex(base16) <--> Binary(base2)
it's the same thing, just the bases are different, converting

Why not add the ability to search by [...] known public key to speed up

Matching against pubkey would be handy (if it doesn't already do this?)

..because main target(puzzle) assumes a public key unknown (only its ripemd160 hash is known).
and if pubkey is known then sequential key search in a limited space (which uses bitcrack) is the stupidest and slowest way to search compared to baby-step-gigant-step algo and pollard-rho/kangaroo algo
when BitCrack compute 10M keys, its checked 10M keys
when BSGS/Pollard compute 10M keys, its checked (10M)^2 = 100000000M keys (!!!..undestand?)

And which bitcrack version supports random key space function ?

This fork https://github.com/pikachunakapika/BitCrack

Code:

-r, --random
    Each point will start in random KEYSPACE

Is this 2123626 million or 2,123,626?
I'm using a Vega 64 with "clBitCrack.exe -b 500 -t 256 -p 1024 -c -u"

? 2123626 Mkey/s . this is unrealistic speed. looks like a bug.
guys how much gives vega56?

Telariust, thank you very much

This function


-r, --random
    Each point will start in random KEYSPACE


must work in software clBitCrack.exe ?

I tried running on my laptops ( AMD A6-3420M APU with HD Graphics AMD Radeon HD 6520G ) - getting an error.

You sure are using this fork of software?

If not I am mistaken took software clBitCrack.exe from this page - https://github.com/brichard19/BitCrack/releases

It absolutely other version software clBitCrack.exe?
In her there is no function "-r  --randoom"  ?

Description does not specify this function, so it is only in this fork - https://github.com/pikachunakapika/BitCrack

Here it is necessary to load completely (green button " Clone or download ") all in ZIP archive, and then to open archive on the computer?

Whether and there is a combined variant of use of functions " - keyspace " and " -r, - randoom ", i.e. that worked so:

For example - we write -- keyspace 100000000000:500000000000 and -- random OR -- random 100000000000:500000000000 then The search is made only in a range 100000000000:500000000000, but casual (random like a flea or a kangaroo ) by jumps?

[Angelo1710]

Can OP please add random (-r) function in the latest version of bitcrack?

Cheers

This version: https://github.com/pikachunakapika/BitCrack
Does not save private keys in txt at all, it is broken.

This is the source code, you need to compile it in executable file (section "Building in Windows/Linux")

https://github.com/pikachunakapika/BitCrack This version does not save key text file at all, just tested it, it's broken. Can someone add -r to the latest Bitcrack version, please?

[avw]

This version does not save key text file at all, just tested it, it's broken.

Maybe bitcrack writing output file to the wrong directory where you're looking?

Well I tried with -o file command and without and no file was saved when the key was found, then I tried the same in the latest version and it worked perfectly.

When I tried on Windows to run the original bitcrack, it saved output file in windows/system32.
Try naming the file non-standard way, run bc, and then searching for the file in system.

Tried and no textfile was found in system32. I really wish someone can add -r to the latest version.

[iparktur]

If to add function " -r, - randoom " in last version, it is desirable to make two variants it is functions:

1 - " -r, - randoom " - the search by casual jumps in all space is made;
2 - " -r START:END, - randoom START:END " - the search by casual jumps in the given (desirable) space is made

OR

1 - if not the function - keyspace - is given then the search by casual jumps in all space is made;
2 - if the function - keyspace - is specified then the search by casual jumps only in the specified space is made;

Got it to work but it seems it just randomly searching in 252-256 space, so it is not 'really' random.

[avw]

It looks like it can work random in the specified keyspace:

https://github.com/pikachunakapika/BitCrack/issues/3
Try "--keyspace START:END" and "-r" flags together
