Getting Started

NerdyPassword nerdyPassword = new NerdyPassword();
System.out.println(nerdyPassword.startGeneratingPassword());

If NerdyPassword() is use the default secure level is 1.

Usage

Predefined Secure Level

Secure Level 0

• Password length: 8
• Same character twice in a row: false
• Min one number: true
• Min one letter: true
• Min one lower and one upper letter: true
• Min one symbol: false
• Symbol lists: non

Secure Level 1

• Password length: 8 - 25
• Same character twice in a row: false
• Min one number: true
• Min one letter: true
• Min one lower and one upper letter: true
• Min one symbol: true
• Symbol lists: 1

Secure Level 2

• Password length: 25 - 50
• Same character twice in a row: false
• Min one number: true
• Min one letter: true
• Min one lower and one upper letter: true
• Min one symbol: true
• Symbol lists: 1, 2, 3

Predefined Symbol Lists

List 1	List 2	List 3	List 4	List 5
'_'	'@'	'*'	','	'('
'-'	'#'	'+'	';'	')'
	'§'	'"'	'.'	'{'
	'$'	'='	':'	'}'
	'%'			'['
	'&'			']'
	'!'			'<'
	'?'			'>'

Examples

Generating password with one of the defined secure level

NerdyPassword nerdyPassword = new NerdyPassword(2);
System.out.println(nerdyPassword.startGeneratingPassword());

Defined password settings with one of the constructors

NerdyPassword nerdyPassword = new NerdyPassword(8, true, true, true, true);
System.out.println(nerdyPassword.startGeneratingPassword());

Generating n password with the same settings

NerdyPassword nerdyPassword = new NerdyPassword();
List<String> passwords = nerdyPassword.startGeneratingPasswords(100);

for (int i = 0; i < passwords.size(); i++) {
  System.out.println(passwords.get(i));
}

Defined password settings

NerdyPassword nerdyPassword = new NerdyPassword(0);
String password = nerdyPassword.setPasswordlength(10, 15).addSymbohList1ToPosibilChars().startGeneratingPassword();

System.out.println(password);

Get errorcode

NerdyPassword nerdyPassword = new NerdyPassword(false);
if (nerdyPassword.startGeneratingPassword() == null) {
  System.out.println(nerdyPassword.getErrorCode());
}

If startGeneratingPassword() returns a null, the error occurred.

Start without default settings

NerdyPassword nerdyPassword = new NerdyPassword(false);

Like "Start without default settings" but as methode

NerdyPassword nerdyPassword = new NerdyPassword();
nerdyPassword.resetAllSettings();

Set sequence of characters for password

CharType[] charTypeSequence = new CharType[8];
charTypeSequence[0] = CharType.UPPER_LETTER;
charTypeSequence[1] = CharType.LOWER_LETTER;
charTypeSequence[2] = CharType.LOWER_LETTER;
charTypeSequence[3] = CharType.LOWER_LETTER;
charTypeSequence[4] = CharType.NUMBER;
charTypeSequence[5] = CharType.NUMBER;
charTypeSequence[6] = CharType.NUMBER;
charTypeSequence[7] = CharType.NUMBER;

NerdyPassword nerdyPassword = new NerdyPassword(0);
nerdyPassword.setCharTypeSequence(charTypeSequence);

System.out.println(nerdyPassword.startGeneratingPassword());

List of Error/Warning Codes

Name	Description
0	No error or warning
401	Min password length have to be > 0.
402	Max password length have to be > 0.
403	Max password length have to be >= Min password length.
501	Min and max password length have to be the same for a charTypeSequence.
502	Password length have to be the same as the charTypeSequence.length.
601	No characters definet for the new password.
701	Numbers are needed but no numbers are definet for the new password.
702	Letters are needed but no letters are definet for the new password.
703	Lower/Upper letters are needed but no lower/upper letters are definet for the new password.
704	Symbols are needed but no symbols are definet for the new password.
