2 | 3 | ### Simple library for generating strong cryptographically secure random passwords. 4 | The Class Library Random-Password-Generator provides an opportunity to generate passwords of following types 5 | 6 | * Random cryptography in various lengths and symbols 7 | * Generation of HexPasswords 8 | * Generation of pinCodes 9 | 10 | ```C# 11 | class Program 12 | { 13 | static void Main(string[] args) 14 | { 15 | // Creating instance of RandomPassGen class with 2 libraries 16 | RandomPassGen NewPass = new RandomPassGen(Library.numbers, Library.alphabetUper); 17 | 18 | // Generating password with length 9 19 | string password = NewPass.NewPassword(9); 20 | // Generating Hexpassword 21 | string Hexpassword = RandomPassGen.HexPassword(); 22 | // Generating pincode 23 | string Pincode = RandomPassGen.PinCode(); 24 | // the output is 25 | Console.WriteLine("Password----->\t{0}\nHexpassword-->\t{1}\nPincode------>\t{2}", password, Hexpassword, Pincode); 26 | 27 | // using NewPassword override method to change Libraries and generate new password 28 | password = NewPass.NewPassword(14, Library.numbers, Library.alphabetUper, Library.symbols); 29 | 30 | 31 | Console.ReadKey(); 32 | } 33 | } 34 | ``` 35 | ### The output is 36 | 37 | > Password-----> SD24YQO85 38 | 39 | > Hexpassword--> 49Ac-87BB-08bB-9f87 40 | 41 | > Pincode------> 1001 42 | 43 | >---------------------------------------- 44 | 45 | ### Installation 46 | To see how to add class library to your project visit: [Add or Remove References](https://msdn.microsoft.com/en-us/library/hh708954.aspx) 47 | ### Simple Usage 48 | Instead of instantiating individual Random objects, I recommend that you create a single Random instance to generate all the random numbers needed by your app. 49 | 50 | > This class library written on C# 6.0, .NET Framework 4.6 Visual Studio 2015 Comunity Edition 51 | -------------------------------------------------------------------------------- /RandomPasswordGenerator/RandomPasswordGenerator/RandomPasswordGenerator.csproj: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | Debug 6 | AnyCPU 7 | {3E474163-3865-43F7-B215-90D6BF39A583} 8 | Library 9 | Properties 10 | RandomPasswordGenerator 11 | RandomPasswordGenerator 12 | v4.5.2 13 | 512 14 | 15 | 16 | true 17 | full 18 | false 19 | bin\Debug\ 20 | DEBUG;TRACE 21 | prompt 22 | 4 23 | 24 | 25 | pdbonly 26 | true 27 | bin\Release\ 28 | TRACE 29 | prompt 30 | 4 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 55 | -------------------------------------------------------------------------------- /.gitattributes: -------------------------------------------------------------------------------- 1 | ############################################################################### 2 | # Set default behavior to automatically normalize line endings. 3 | ############################################################################### 4 | * text=auto 5 | 6 | ############################################################################### 7 | # Set default behavior for command prompt diff. 8 | # 9 | # This is need for earlier builds of msysgit that does not have it on by 10 | # default for csharp files. 11 | # Note: This is only used by command line 12 | ############################################################################### 13 | #*.cs diff=csharp 14 | 15 | ############################################################################### 16 | # Set the merge driver for project and solution files 17 | # 18 | # Merging from the command prompt will add diff markers to the files if there 19 | # are conflicts (Merging from VS is not affected by the settings below, in VS 20 | # the diff markers are never inserted).
