Is this code ASP?

[marhanen]

OK i have this code but i'm not sure if its asp.net all he said was that it runs in .net and if it is how would i be able to run it.


using System;
using System.Collections;
using System.Security.Cryptography;
using System.Text;

public class PasswordGenerator
{
private const int DefaultMaximum = 25;
private const int DefaultMinimum = 25;
private string exclusionSet;
private int maxSize;
private int minSize;
private char[] pwdCharArray = "BCDFGHJKLMNPQRSTVWXYZ0123456789".ToCharArray();

public PasswordGenerator()
{
Minimum = DefaultMinimum;
Maximum = DefaultMaximum;
Exclusions = null;
}


private char[] GetAvailableChars()
{
ArrayList result = new ArrayList(pwdCharArray);
char[] exclusions = String.Empty.ToCharArray();
if (exclusionSet != null)
{
exclusions = exclusionSet.ToCharArray();
}
foreach (char exclusion in exclusions)
{
result.Remove(exclusion);
}

return (char[]) result.ToArray(typeof(char));
}

public string Generate()
{
int size = maxSize;
byte[] data = new byte[1];
char[] availableChars = GetAvailableChars();

RNGCryptoServiceProvider crypto = new RNGCryptoServiceProvider();
crypto.GetNonZeroBytes(data);
size = (data[0] % (maxSize - minSize)) + minSize;
data = new byte[size];
crypto.GetNonZeroBytes(data);
StringBuilder result = new StringBuilder(size);

foreach(byte datum in data)
{
result.Append(availableChars[datum % (availableChars.Length - 1)]);
}

return result.ToString();
}


public string Exclusions
{
get { return exclusionSet; }

set { exclusionSet = value; }

}

public int Maximum
{
get { return this.maxSize; }

set
{
this.maxSize = value;
if (this.minSize >= this.maxSize)
{
this.maxSize = PasswordGenerator.DefaultMaximum;
}
}

}

public int Minimum
{
get { return this.minSize; }

set
{
this.minSize = value;
if (PasswordGenerator.DefaultMinimum > this.minSize)
{
this.minSize = PasswordGenerator.DefaultMinimum;
}
}

}
}


its kind of old so i cant ask him myself

thanks

It looks to be C# code which does run under .net; you should be able to get it to run on a .net page.

[marhanen]

ok so how would i put it on a .net page.

You need to create a class PasswordGenerator.cs and place that file into your App_Code folder (ASP.Net 2.0). Then you need to create an object of that class, something like below:

PasswordGenerator pwd = new PasswordGenerator();

//display the password into a label for testing
lblMsg.Text = pwd.Generate();

[otaku149]

If your goal is to generate a password, you can simply use the The GUID method instead:

C#

string pwd = System.Guid.NewGuid().ToString().Substring(0, 12).Replace("-", "").ToUpper();
Response.Write(pwd);


VB.Net

Dim pwd As String = System.Guid.NewGuid().ToString().Substring(0, 12).Replace("-", "").ToUpper()
Response.Write(pwd)

its kind of like a key generator i wanted to try and get something that would randomly choose a number or letter from a list and have it so its so long and then have it paste it in a file andhave no duplicates

i want it to not use certain letters and numbers and i would want it to be like 25 choices

a78fd-7ajf3-as4r2-a84hd-as74h

i want to be able to tell the program to only use these numbers and letters

i have another code which is .vb that i'll post in the other forum.

The PasswordGenerator Class will do the job. Minimum and Maximum values are 25 to get your desired length. Enter letters and numbers that you don't want into the pwd.Exclusions:


PasswordGenerator pwd = new PasswordGenerator();
pwd.Minimum = 25;
pwd.Maximum = 25;
pwd.Exclusions = "0, 1, 2, 3, A, B, C, D";
Response.Write(pwd.Generate());


This will generate a 25 length key without Exclusions, something like:

And if you wish to add separator like below:

V6HRJ-XKQ56-LWQRJ-Z7JQN-QF4PV

You will need to modify the class:

PasswordGenerator.cs

using System;
using System.Collections;
using System.Security.Cryptography;
using System.Text;

public class PasswordGenerator
{
private const int DefaultMaximum = 24;
private const int DefaultMinimum = 24;
private string exclusionSet;
private int maxSize;
private int minSize;
private char[] pwdCharArray = "ABCDFGHJKLMNPQRSTVWXYZ0123456789".ToCharArray();

public PasswordGenerator()
{
Minimum = DefaultMinimum;
Maximum = DefaultMaximum;
Exclusions = null;
}


private char[] GetAvailableChars()
{
ArrayList result = new ArrayList(pwdCharArray);
char[] exclusions = String.Empty.ToCharArray();
if (exclusionSet != null)
{
exclusions = exclusionSet.ToCharArray();
}
foreach (char exclusion in exclusions)
{
result.Remove(exclusion);
}

return (char[])result.ToArray(typeof(char));
}

public string Generate()
{
int size = maxSize;
byte[] data = new byte[1];
char[] availableChars = GetAvailableChars();

RNGCryptoServiceProvider crypto = new RNGCryptoServiceProvider();
crypto.GetNonZeroBytes(data);
size = (data[0] % (maxSize - minSize)) + minSize;
data = new byte[size];
crypto.GetNonZeroBytes(data);
StringBuilder result = new StringBuilder(size);

foreach (byte datum in data)
{
result.Append(availableChars[datum % (availableChars.Length - 1)]);
}

return InsertSeparatorEvery(result.ToString(), "-", 5);
}

public string InsertSeparatorEvery(string String, string Separator, int Count)
{
StringBuilder final = new StringBuilder();
for (int i = 0; i <= String.Length - 1; i += Count)
{
if (!(i + Count > String.Length))
{
final.Append(String.Substring(i, Count) + Separator);
}
else
{
final.Append(String.Substring(i) + Separator);
}
}
return final.ToString().Substring(0, final.Length - 1);
}

public string Exclusions
{
get { return exclusionSet; }

set { exclusionSet = value; }

}

public int Maximum
{
get { return this.maxSize; }

set
{
this.maxSize = value;
if (this.minSize >= this.maxSize)
{
this.maxSize = PasswordGenerator.DefaultMaximum;
}
}

}

public int Minimum
{
get { return this.minSize; }

set
{
this.minSize = value;
if (PasswordGenerator.DefaultMinimum > this.minSize)
{
this.minSize = PasswordGenerator.DefaultMinimum;
}
}

}
}



Generate the key

protected void Page_Load(object sender, EventArgs e)
{
PasswordGenerator pwd = new PasswordGenerator();
pwd.Minimum = 25;
pwd.Maximum = 25;
pwd.Exclusions = "0, 1, 2, 3, A, B, C, D";
Response.Write(pwd.Generate());
}

[marhanen]

so running it i would put PasswordGenerator.cs as a file and then have the generate a key on the website like in a form?

Yes, create a class PasswordGenerator.cs with the code I gave you and place that file into your folder App_Code. In your .aspx page, create an instance of that class like below:

PasswordGenerator pwd = new PasswordGenerator();
pwd.Minimum = 25;
pwd.Maximum = 25;
pwd.Exclusions = "0, 1, 2, 3, A, B, C, D";
lblMsg.Text = pwd.Generate();

In the above example, pwd.Generate() will generate the key, I have placed the generated key into a label but place it whatever you want.

[marhanen]

thanks man that really helped.

[otaku149]

you are welcome :)
