Find private key with bitcrack stride and last 7 hex digits Puzzle 66
Script assigns 7 random hex digits
writes to and checks tried.txt so never repeats the same 7 hex digits in same order.
no more that 2 adjacent identical hex characters. Limits the possible combinations to approx. 33 million
Example to test this method can find private key of a specific public address.
Test Address 1K2wh7bdCYgFeipT8fnCS3GknWLKHPgJq5 lies in keyspace 66 private key 000000000000000000000000000000000000000000000003E838B13505B26867 we know in this example last 7 hex 5B26867
run cuBitCrack OR BitCrack.exe -b 128 -t 256 -p 1380 --stride 10000000 --keyspace 20000000005b26867:3ffffffffffffffff -o FOUND.txt -c 1K2wh7bdCYgFeipT8fnCS3GknWLKHPgJq5
the python script generates 7 random hex digits and places them in the end of the keyspace example 20000000005b26867
Tries for a match if no match writes the tried to tried.txt checks tried.txt so no repeats then generates a new unique 7 hex digits continuously.
To run program run adust -b 128 -t 256 -p 1380 in script to match your gpu adjust time.sleep(60) # Wait for 60 seconds before restarting to match your gpu time to complete the total keyspace
run python3 p66.py and have bitcrack.exe in same folder a tried.txt database will be formed so no duplicate tries. DO not use command line below except to prove works. run python3 p66.py or python3 pattern66.py for linux
Example of operation
BitCrack.exe -b 128 -t 256 -p 1380 --stride 10000000 --keyspace 20000000005b26867:3ffffffffffffffff -o FOUND.txt -c 1K2wh7bdCYgFeipT8fnCS3GknWLKHPgJq5
