fnv1a cracker in go. original version by @cybercdh from https://github.com/cybercdh/hacks/tree/master/sunburst
Performance is 4 times faster than the native go fnv1a lib on short strings. On large strings it's still 20% faster. Benchmarks in the bench folder.
This code does the XOR used in the sunburst malware in the end, so drop that if you want to use it for something else.
Pipe the output of some other tool or file, e.g.
cat processes.txt | go run main_optimized_lower_only.go
or you can feed it a single process name on the command line:
go run main_optimized_lower_only.go someprocess
or you can feed it the output of another tool like e.g. john:
john --incremental:LowerNum --stdout | go run main_optimized_lower_only.go
(or prince mode, markov, ...)
Only feed lowercase strings.
