Overview

Package dump implements an haveibeenpwned.com dump scanner. It is designed to operate on HIBP SHA-1 dumps which are ordered by hash. It will work with dumps ordered by prevalence, too. But processing those will take much, much longer.

Unfortunately these dumps need to be unpacked before use, since there is no 7z implementation for Go at the time of this writing.

Example
ctx := context.Background()
scanner, err := New("path/to/hibp-dump")
if err != nil {
	panic(err)
}
matches := scanner.LookupBatch(ctx, []string{
	"list",
	"of",
	"sha1",
	"hashes",
})
fmt.Println(matches)
