import java.util.TreeMap;
public class TruckRace1 {
public static HashSet<String> getPIDs (Map<String,String>nameToPID ){
HashSet<String> pidSet = new HashSet<>();
for(String ids: nameToPID.values()){
pidSet.add(ids);
}
return pidSet;
}
public static void main(String[] args) {
Map<String,String> pids = new TreeMap<>();
pids.put("John","123");
pids.put("Jason","124");
pids.put("Peter","125");
pids.put("Alice","126");
pids.put("Peny","129");
HashSet<String> ids = getPIDs(pids);
for(String id:ids){
System.out.println(id);
}
}
}
The types of attacks that are known to be thwarted by complex passwords that are combinations of upper and lower case letters, numbers, and special characters are said to be Brute Force Attacks.
What is Brute Force Attacks?
This is known to be an attack that is said to be a very crude type of attack and it is often seen as a brute-force attack.
Note that is one that does not depend on lists of passwords, but it is one that often tries all the very possible combinations of permitted character types.
Hence, this type of attack was known to be historically seen as ineffective, and it is said to be The types of attacks that are known to be thwarted by complex passwords that are combinations of upper and lower case letters, numbers, and special characters are said to be Brute Force Attacks.
