Anyone how to calculate pub key length

What do you mean? How many characters/digits in a pubkey? Compressed, Uncompressed?
compressed, starts with 02 or 03:

Code:

03284635D3127EA5E6AFFAD7213BED1BBB63535D9B2B4E22F63ED5093CB30FDAA5

uncompressed:

Code:

04284635D3127EA5E6AFFAD7213BED1BBB63535D9B2B4E22F63ED5093CB30FDAA5F30279671068A413636A6116F3E43CFB2B476067C8CF6F801EE68E8C3E6D5F4F

I know difference from compress and uncompress i want to know how to check what is lenght and which range belong example i saw here 64 is from 8:f if you explain

Ok, it sounds like you are talking private key versus public key. Because 64 bits is from 8000000000000000:FFFFFFFFFFFFFFFF . The pubkeys are always the same length, just start with different number, 02, 03, 04 (uncompressed) and there is no way of knowing what range a pubkey lies in, unless you have the private key.

I see but how then you set a range when search with kangaroo you guessing a range or you know something also what about hash160 is there some converter to pub key

For most people here, we know the ranges that the puzzle addresses lie in. Look here and you can see all the ranges of the puzzle wallets
https://bitcointalksearch.org/topic/m.53649852 only every 5th one has a known pubkey in which you can use this kangaroo program. The other wallets would need to be brute forced.

@MrFreeDragon

HT Max : 9 [@ 01598C]
HT Min : 0 [@ 000003]
HT Avg : 0.88
HT SDev : 0.94

This is the distribution of DP in the HashTable:
9 DP at hash 01598C (largest entry)
0 DP at hash 000003 (smallest)
0.88 DP per hash in average
0.94 standard deviation of DP distribution in the HashTable

Sorry for old bump, but using the example quoted, does it mean that 9 kangaroos made it to the 01598C? JLP says the "largest entry" does it mean the longest? Meaning the longest (jump distance that found a dp) that any kangaroos has made it is 01598C? If so, do you want this number higher? Example, would FA02BC119 be better than 01598C?

Can anyone try my tool on a 2080ti? On a 2080S it gets around 1300MKeys/sec when using 24-bit DP.

is this Bitcrack GPU version ?!

No,
Bitcrack support GPU

Thank you brichard19 for OpenCL version of Pollard's kangaroo
I get 263.40 Mpt/s for my RX480 8Gb.

what is your gpu-mem-usage setting?

I've used --gpu-mem-usage 0.5

pubkey less then 85Bytes.

4000 Mkey/sec totla.

-d - default

nothing found in 1,5h Count - 2^42 . Only 1 dead kangaroo.

why not founded 1 privkey ?

How to fix it ?
Huh

First you range in not less 85bit but equil to 85bit

Why bro

?? My range from 0 to 85.

How to set range from 0 to 85 Huh

?

Secon bit and bytes very different things..
Third Expected OP for your range = 2^ 43.55
Fourth, the public key must lie in a given range, otherwise it will never be found.

Think it's worth running Vega VIIs with this program? I took all AMD cards offline b/c no one had openCL or one that was worth a flip. I know the Vega VIIs kick a$$ compared to any RTX or GTX card when it comes to mining ethash. But that's because they have 16GB HBM2 memory and a wide bus. Not sure the same would be true for this program.

speed eclambda on 2080ti 1350Mpt/s
on 5700 - 640Mpts/s --gpu-mem-usage 0.8
bad news that there no multi-gpu support.
Kangaroo from JeanLuc have multi-gpu support but nvidia only GPU
