View 1 RepliesC# - Bob Jenkins Perfect Hash Function In .Net?
Apr 20, 2012I am trying to convert Bob Jenkins perfect hash function from C# to VB.Net and I am stuck at following.
a += (UInt32)(url[k + 0] + (url[k + 1] << 8) + (url[k + 2] << 16) + (url[k + 3] << 24))
How can I write above statement in VB.Net?
a is UInt32
url is String
k is Integer
I tried the following but it doesn't work.
a += url(k + 0) + (url(k + 1) << 8) + (url(k + 2) << 16) + (url(k + 3) << 24)
To avoid manually doing type casting, I am using "Option Strict Off"
Hash Function For 2D Barcode Data?
Mar 16, 2011I am writing a string of about 120 characters to a 2D barcode. Along with other text, the string contains a unique ticket number. I want to ensure that someone doesn't generate counterfeit tickets by reading the 2D barcode and generation their own barcoded tickets.
I would like to hash the string and append the hash value to what gets embedded in the barcode. That way I can compare the two on reading and see if the data had been tampered with. I have seen several hash function that return 64 bytes and up but the more characters you embed in a 2D barcode the bigger the barcode image becomes. I would like an algorithm that returns a fairly small value. It would also be nice if I could provide the function my own key. Collision is not that big of a deal. This isn't any kind of national security application.
C# - Hash Function To Obtain Limited Length Result
Apr 18, 2012I need to hash a number (about 22 digits) and the result length must be less than 12 characters. It can be a number or a mix of characters, and must be unique. (The number entered will be unique too). For example, if the number entered is 000000000000000000001, the result should be something like 2s5As5A62s. I looked at the typical, like MD5, SHA-1, etc., but they give high length results.

Database Veiw Adding A Update - Delete And Email Function From The Selection From A Checkbox

Getting A Different Hash Value?
Nov 16, 2011I am at a bit of a loss at the moment. What I am basically writing is the password elements of a membership system. What I do is generate a random salt value, take the registered password, combine the two and then pass the new string through a function which will generate a SHAManaged 512 hash.
I then convert the hash and salt string into Byte arrays and store these in my database.The problem comes when I then compare a login attempt against the original value I am being supplied with a completely different hash for the password being presented by the user, even though it should be exactly the same.
Here is my code when someone registers their new account:

MD5 Hash Of Images?
Nov 7, 2010I know MD5 hashes have been asked about 1000+ times, but this question is slightly different.I am looking to find the true MD5 hash of an image, but without using a string for the file's location. I am looking to be able to call on the image inside of a picturebox rather than somewhere on my computer or the internet.
For example, I want to find the MD5 hash of an image inside of my picturebox.
If this doesn't make sense, please ask any questions you may have.

Anchor - If Statement Using The Value Of Hash In URL?
Feb 6, 2012I have a page with a URL that includes a hash value (www.mysite.com/#123).What I want to do is use that value to determine what is displayed on the page - much like using a querystring.I am using the hash value because the content on the page can be changed client side (I am avoiding page reloads where possible) - if the user then links to another page and uses the back button to return, I need to use the hash value to display the page as it was when they left it.So I'm looking for an if statement that will look something like this:

C# - Getting Hash Of A List Of Strings?
Mar 21, 2009I would like to write a function GetHashCodeOfList() which returns a hashcode of a list of strings regardless of order. Given 2 lists with the same strings should return the same hashcode.
ArrayList list1 = new ArrayList()
list1.Add("String1");
list1.Add("String2");
[Code].....
I can first sort the list, then combine the sorted list into 1 long string and then call GetHashCode(). However sorting is a slow operation. I can get the hash of each individual string (by calling string.GetHashCode()) in the list, then multiplying all hashes and calling Mod UInt32.MaxValue. For Example: "String1".GetHashCode() * "String2".GetHashCode * ... MOD UInt32.MaxValue. But this results in a number overflow.
Compare Two Hash Values?
Aug 10, 2009I'm trying to figure out a way to compare two "salted-hash" strings. How can I do this? I know that the salt is a random generated value that's appended to the plain text, then we just compute the hash of that new string.So how can I compare these two values?

Php - How To Produce A Different Md5 Hash With Different Encodings
Apr 1, 2011I am porting over some code from .net (vb) to php and I came across some md5 hashing that I can't reproduce in php. In the .net one there are two functions one uses UTF-8 encoding and the other uses Unicode encoding. The output is a different hash when passed in a string
// First function (returns GUID)
Dim oHasher As Cryptography.MD5 = Cryptography.MD5.Create()
Dim oEncoder As New System.Text.UTF8Encoding()
Dim csData() As Byte

but they both produce the same result. Is it possible to produce the same results in php with md5 hashing?

View 2 Replies.net - Different Increase In Email Size Using SMTP Class To Send An Email As Opposed To Outlook?

The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.
