Functions

• WhirlpoolHashUnique(string[], times, salt[], bool: iter_append = false)
  string[] - Takes the string you would like to hash.
  times - How many times does the function have to hash the string before returning the value.
  salt[] - Takes a unique salt that will be concatenated with the string and hashed together.
  (R2-only) bool: iter_append - Choose if you'd like to append the salt for every iteration or not. It increase the security but it slightly slows down the process.
  returns the Whirlpool hashed string.
  
  Example:
  
  
  pawn Код:

  WhirlpoolHashUnique("TestingString", "RandomStringAsSalt", 500, true);

  This function will returned a Whirlpool string ("TestingString") hashed 500 times with an unique salt ("RandomStringAsSalt") concatenated for every iteration.
  
  
• WhirlpoolHashRandom(string[], times, salt[], salt_length, bool: iter_append = false)
  string[] - Takes the string you would like to hash.
  times - How many times does the function have to hash the string before returning the value.
  salt[] - Reference string that contains the salt returned by randomString();
  salt_length - How many characters will contain the salt.
  (R2-only) bool: iter_append - Choose if you'd like to append the salt for every iteration or not. It increase the security but it slightly slows down the process.
  returns the Whirlpool hashed string.
  
  Example:
  
  
  pawn Код:

  // Make sure the local variable length is big enough as you've entered in the hashing function.
  new saltUsed[50];
  WhirlpoolHashRandom("TestingPassword", saltUsed, 250, 45, true);

  This function will returned a Whirlpool string ("TestingString") hashed 250 times with an unique salt randomly generated of 45 length and stored inside "saltUsed" concatenated for every iteration.

Examples

pawn Код:

new saltUsed[50], hashedPassword1[129], hashedPassword2[129];
    
strcat(hashedPassword1, WhirlpoolHashRandom("password", 500, saltUsed, 24), 129);
printf("hashedPassword1 = %s", hashedPassword1);    
    
strcat(hashedPassword2, WhirlpoolHashUnique("password", saltUsed, 500), 129);
printf("hashedPassword2 = %s", hashedPassword2);    
    
if(!strcmp(hashedPassword1, hashedPassword2, false))
    print("The password is correct.");
else
    print("The password is not correct.");

Speed Tests

Testing Code:

printf("WhirlpoolHashUnique stopped executing, hash is %s.", hashedPassword2);
        
printf("The entire process took %d milliseconds.", GetTickCount() - timer);

It is useless to hash a password more than once. You already have support for a salt which is plenty secure.

I think you're a little bit misinformed regarding hashing and salts or password security whatsover.

Hashing a password once is not safe AT ALL for brute-force attacks.
Depending on the computer performances, it may take up to few minutes in order to find your plain text password.

Salting is just a little extra that slightly increases the password security, because it's unlikely the dictionary used for the brute-force attack will have the salt.

However, hashing an hash multiple times (if not hundreds or thousands, like in my example) will turn the brute-force attack into something extremely slow because the computer will need to find every correct combination for every single hash generated, which will take a lot depending on the amount of iterations used on the function.

The question is: what's the good combination of security and speed? Usually, a slow function means a safer password, but in SA-MP, as ****** explained here you need to find an acceptable amount of iterations in order to not make the gameplay experience annoying.

R2 version added.

Test:

Quote:

WhirlpoolHashUnique("Hello world", 4, "Hello"); WhirlpoolHashUnique("Hello world", 4);

What about a single function?

I used MAX_SALT_LENGTH to avoid error for

"
realsalt = salt;
"

ofc, you can use ofc a different way.

[GiamPy.]

In your method there would be no way to retrieve the salt generated, that's why I have made two functions.

If I'd then try to do something like WhirlpoolHashUnique("Hello world", 4, string); the function will not store the randomly generated salt into string, but it will be used for the hash concatenation.

[ReVo_]

I dont see a way to take the random salt in your WhirlpoolHashRandom too, correct me if i'm wrong.

stock WhirlpoolHashRandom(string[], times, salt[], salt_length, bool: iter_append = false)

salt isnt passed as reference, so you dont store the salt.

EDit: sorry for who read, string are always passed as reference.

[GiamPy.]

Yes, it is stored in the variable used in the third parameter.
Strings are always passed as reference.

[ReVo_]

Yeah, you are right. I cant edit due to connect problems anyway too shit C# llanuange with ref/out keywords let me do this fail.

Anyway im pretty sure can be done with my code i will see anothet day if i remeber this include.
