# PasswordGenerator

A Password Generating Algorithm to generate password based in users inputs. 

# Algorithm

    /*

    * actual algorithm to generate password

    *  @assumptions

    *   1. From the should be included words set and special char set, 1 word from each set will be picked

    *   2. from the msut be included words list and char list , all words will be picked

    *   3. if any specific no. needs to be included, add the numbers given

    *   4. How many no. of uppercase needed = randomly select equivalent no. of chars and change their cases.

    *   5. total numeric values will be used to add extra random numbers

    *   6. remembering Strength defined the complexity in terms of how hard the password can be remembered .

	*

	

	@Steps:

	1. Get the data from user

	2. first process the "Has to be included constrainsts", append them to final string

	3. then process Should be included words, 

		1. pick random word from Chars, append them to final string

		2. pick random word from special chars,append them to final string

	4. then process numbers which should be included,append them to final string

	5. once the numbers get added, if the number count needed is still > 0, add more random numbers till the count has been reached,append them to final string

	6. once you get final string, Now it's time to see the remebering strength choosen by user

		1. LOW	- easy to remeber, that is no need to change any thing as the above logic is for LOW strength.

		2. MEDIUM - less easy to remember, make it a bit tough, Keep the chars as it is and shuffle the special chars and nums, Rearraange then for final string

		3. HIGH - it should be tough, hard to remeber, shuffle all chars randomly and make the final string

		

	@improvement Scope

		1. instead of random shuffling, can create a shuffle algorithm, which takes input from user and shuffle accordingly.

		2. ',' is not considered as special char here, the algo can be mould to use ',' also in password

		3. password generation time can be optimized

		4. unncessary assumptions can be removed and algo can be refactored.

		5. other small boundry cases improvemnts still possible.
