Leaked password check
With this library you can check the password is probably leaked or not.
Pre generated bitset DB includes 6 Million leaked passwords stored in bloom filter bitset.
To generate your own bitset DB head into Db-generate and follow instructions.
Bloom filter
The current configuration is a 1 in 1 Million false positive rates. With bloom filter, you can make sure if data is not stored in the bitset. But bloom filter can generate false positives.
To change error rate, you need to generate your own bitset DB. After that you can change bitset DB like this
package main
import (
"github.com/theykk/leaked-password"
"os"
"io"
)
func main() {
myDB, _ := os.Open("my.db")
defer myDB.Close()
leakedpassword.CustomReader = myDB
}
Usage
package main
import (
"github.com/theykk/leaked-password"
)
func registerUser(username, password string) error {
// Check password is leaked
isLeaked, err := leakedpassword.IsLeaked(password)
if err != nil {
return err
}
if isLeaked {
// Password is leaked do something
}
return nil
}
