Brainflayer is 4 years old, hasn't been updated since then,

I totally re-wrote brainflayer from scratch, added dozens of new switches for finding private keys from public keys, I also wrote dozens of new unix like cmd-line utilitys to assist in hacking btc

I also wrote dozens of shell scripts to run 24/7 to automate btc hacking on server startup.

I rewrote vanity-gen, stripped out all the bs, and put in bloom-filters to find private-keys for address databases placed in bloom-filters ( 32gb+), completely re-wrote all the GPU C++ code that run's in opencl so it can run at amd or nvidia

snort block-parser is 2014 doesn't work, and hasn't been maintained, I just posted the code to parse bitcoin blocks and get the addresses yesterday on this forum ( see bitcoin hacking university )

bitcrack I have no idea, but it sounds lke a 'linear collider clone', which means it just linear searchs private-key space 1 to N, where N is 10**77, so maybe if every atom in the known universe ran the software, then in 10k years you might hit that one key you were looking for,

What I do is look  for 200million addreses at once, 150M-keys/sec 1060 class gpu cards, and the search space is based on DLP known working algos, I don't care about any particular address I just want to find their private-keys and store them

Then you running the mining-pool  collector ( I posted yesterday ) run every ten minutes to get new addresses before they make it to the block-chain, and everytime a new address is used, you look to see with a bloom filter whether you have that private key, if you do then you can store, or sweep.

I have lost interest in this subject after 5+ years of hacking btc, so I'm just looking for students interested in this crap. Sort of like Ed Thorpe teaching MIT kids how to count cards.
