Just to clarify, is the filter precomputed? Yes, precomputed bloom filter, same as original keyhunt but Slait version has a few enhancements. How much time it takes to find a #75 key ? Only few seconds? Yes, only a few seconds as you can see in the .gif Here is scanning some ranges, about 200 seconds for each subrange of 76 bits. ❯ ./keyhunt -m bsgs -f 135.txt -D deep.txt -n 0x1000000000000 -k 16384 -t 192 -q -s 1 -S [+] Version 1.0.4.20260113 Slait Edition, developed by AlbertoBSD [+] K factor 16384 [+] Threads : 192 [+] Quiet thread output [+] Stats output every 1 seconds [+] Mode BSGS sequential [+] Loaded 13 ranges from deep.txt [+] Opening file 135.txt [+] Added 1 points from file [+] Range [+] -- from : 0x5851eb8551eb8550000000000000000000 [+] -- to : 0x5851eb8551eb855fffffffffffffffffff [+] N = 0x1000000000000 [+] Bloom filter for 274877906944 elements : 942249.56 MB [+] Bloom filter for 8589934592 elements : 29445.30 MB [+] Bloom filter for 268435456 elements : 920.17 MB [+] Allocating 4096.00 MB for 268435456 bP Points [+] Reading bloom filter from file filters/bloom/k16384n0x1000000000000/keyhunt_bsgs_1_274877906944.blm (headers) Done!

1. Check your hard drive space; it should be more than ~300GB (~200GB source + ~100GB fuse filter) 2. Increase the swap file by at least 80GB, or better yet, 120GB After that, the problem will go away You've already lost 256 out of 54 packets, which means you've lost ~1/5 of your original file.

How much swap space should I have to generate fuse tables to fill 1T of RAM ? I tried a few lower values from your table but if using more than -k 16384 and -n 0x400000000000 it simply fill all the available 1T RAM and also 2T of swap space and then the program quit because swap is not enough. -x bloom works correctly but -x fuse it is not clear how much swap / ssd space should I have.

I recommend Linux. 1 TB RAM, 1 TB swap, ~4 TB hard drive (1 TB swap + 3 TB source data) Ready fuse filter ~750 GB For an approximate calculation, run ./keyhunt -m bsgs -f 135.txt -D deep.txt -n 0x1000000000000 -k 4096 -n 0x400000000000 -t 192 -s 1 -S During the build, check how much RAM is used and the size of the filters/tmp folder. Multiply the resulting values by 4 to get the correct values.

It's not working, already tried even with 2T swap , the programs fills 1T of RAM then fills all 2T of swap and then because not having enough swap , it quits. If the values are lower than -k 16384 and -n 0x400000000000 it works fine, if the values are higher then it won't work. It needs more swap. I will check the size of /tmp folder to get the correct values.
