  • Need example for BouncyCastle PGP File encryption in C#

    - by Daniel Brink
    Hi, I'm trying to write an c#.net app to encrypt files using my private key (in ascii format) and any other public key (also in ascii format). The BouncyCastle library looks like the correct thing to use, but I cannot find documentation for C#. Could anyone please give me an example of how to use BouncyCastle to encrypt a file. Thank you.

  • Find kth smallest element in a binary search tree in Optimum way

    - by Bragaadeesh
    Hi, I need to find the kth smallest element in the binary search tree without using any static/global variable. How to achieve it efficiently? The solution that I have in my mind is doing the operation in O(n), the worst case since I am planning to do an inorder traversal of the entire tree. But deep down I feel that I am not using the BST property here. Is my assumptive solution correct or is there a better one available ?

  • 'Could not find RubyGem bundler', even though it is…

    - by ashleyw
    I'm running Ruby 1.9.2preview1 (via RVM), and Bundler 0.9.18. If I execute bundle install, it works fine until the point where I don't have the correct permissions to install a gem. However if I execute sudo bundle install, it spits out that it 'Could not find RubyGem bundler'. How can this be, why is the behaviour changing when using sudo? Thanks

  • Html.CheckBoxFor() checked problem in ASP.Net MVC 2

    - by inolen
    It doesn't seem that the Html.CheckBoxFor helper adds the correct "checked" attribute when rendering the HTML. I have a bool property rendered like so: <%= Html.CheckBoxFor(m => m.Visible) %> And the outputted HTML is this: <input type="checkbox" value="true" name="Visible" id="Visible"> Is there some particular reason it does not add the "checked" attribute when the value is true?

  • iPhone 3DES encryption key length issue

    - by Russell Hill
    Hi, I have been banging my head on a wall with this one. I need to code my iPhone application to encrypt a 4 digit "pin" using 3DES in ECB mode for transmission to a webservice which I believe is written in .NET. + (NSData *)TripleDESEncryptWithKey:(NSString *)key dataToEncrypt:(NSData*)encryptData { NSLog(@"kCCKeySize3DES=%d", kCCKeySize3DES); char keyBuffer[kCCKeySize3DES+1]; // room for terminator (unused) bzero( keyBuffer, sizeof(keyBuffer) ); // fill with zeroes (for padding) [key getCString: keyBuffer maxLength: sizeof(keyBuffer) encoding: NSUTF8StringEncoding]; // encrypts in-place, since this is a mutable data object size_t numBytesEncrypted = 0; size_t returnLength = ([encryptData length] + kCCBlockSize3DES) & ~(kCCBlockSize3DES - 1); // NSMutableData* returnBuffer = [NSMutableData dataWithLength:returnLength]; char* returnBuffer = malloc(returnLength * sizeof(uint8_t) ); CCCryptorStatus ccStatus = CCCrypt(kCCEncrypt, kCCAlgorithm3DES , kCCOptionECBMode, keyBuffer, kCCKeySize3DES, nil, [encryptData bytes], [encryptData length], returnBuffer, returnLength, &numBytesEncrypted); if (ccStatus == kCCParamError) NSLog(@"PARAM ERROR"); else if (ccStatus == kCCBufferTooSmall) NSLog(@"BUFFER TOO SMALL"); else if (ccStatus == kCCMemoryFailure) NSLog(@"MEMORY FAILURE"); else if (ccStatus == kCCAlignmentError) NSLog(@"ALIGNMENT"); else if (ccStatus == kCCDecodeError) NSLog(@"DECODE ERROR"); else if (ccStatus == kCCUnimplemented) NSLog(@"UNIMPLEMENTED"); if(ccStatus == kCCSuccess) { NSLog(@"TripleDESEncryptWithKey encrypted: %@", [NSData dataWithBytes:returnBuffer length:numBytesEncrypted]); return [NSData dataWithBytes:returnBuffer length:numBytesEncrypted]; } else return nil; } } I do get a value encrypted using the above code, however it does not match the value from the .NET web service. I believe the issue is that the encryption key I have been supplied by the web service developers is 48 characters long. I see that the iPhone SDK constant "kCCKeySize3DES" is 24. So I SUSPECT, but don't know, that the commoncrypto API call is only using the first 24 characters of the supplied key. Is this correct? Is there ANY way I can get this to generate the correct encrypted pin? I have output the data bytes from the encryption PRIOR to base64 encoding it and have attempted to match this against those generated from the .NET code (with the help of a .NET developer who sent the byte array output to me). Neither the non-base64 encoded byte array nor the final base64 encoded strings match.

  • Issues POSTing XML to OAuth and Signature Invalid with Ruby OAuth Gem

    - by thynctank
    [Cross-posted from the OAuth Ruby Google Group. If you couldn't help me there, don't worry bout it] I'm working on integrating a project with TripIt's OAuth API and am running into a weird issue. I authenticate fine, I store and retrieve the token/secret for a given user with no problem, I can even make GET requests to a number of services using the gem. But when I try using the one service I need POST for, I'm getting a 401 "invalid signature" response. Perhaps I'm not understanding how to pass in data to the AccessToken's post method, so here's a sample of my code: xml = <<-XML <Request> <Trip> <start_date>2008-12-09</start_date> <end_date>2008-12-27</end_date> <primary_location>New York, NY</primary_location> </Trip> </Request> XML` response = access_token.post('/v1/create', {:xml => xml}, {'Content-Type' => 'application/x-www-form-urlencoded'}) I've tried this with and without escaping the xml string before hand. The guys at TripIt seemed to think that perhaps the xml param wasn't getting included in the signature_base_string, but when I output that (from lib/signature/base.rb) I see: POST&https%3A%2F%2Fapi.tripit.com%2Fv1%2Fcreate&oauth_consumer_key %3D%26oauth_nonce %3Djs73Y9caeuffpmPVc6lqxhlFN3Qpj7OhLcfBTYv8Ww%26oauth_signature_method %3DHMAC-SHA1%26oauth_timestamp%3D1252011612%26oauth_token %3D%26oauth_version%3D1.0%26xml%3D%25253CRequest%25253E %25250A%252520%252520%25253CTrip%25253E%25250A %252520%252520%252520%252520%25253Cstart_date%25253E2008-12-09%25253C %252Fstart_date%25253E%25250A %252520%252520%252520%252520%25253Cend_date%25253E2008-12-27%25253C %252Fend_date%25253E%25250A %252520%252520%252520%252520%25253Cprimary_location%25253ENew %252520York%252C%252520NY%25253C%252Fprimary_location%25253E%25250A %252520%252520%25253C%252FTrip%25253E%25250A%25253C%252FRequest%25253E %25250A This seems to be correct to me. I output signature (from the same file) and the output doesn't match the oauth_signature param of the Auth header in lib/client/ net_http.rb. It's been URL-encoded in the auth header. Is this correct? Anyone know if the gem is broken/if there's a fix somewhere? I'm finding it hard to trace through some of the code.

  • How should I proceed to upgrade from TFS2008 to TFS2010

    - by Stephane
    Hi, We have a TFS2008 server with multiple team projects (about 20) What is the best way to migrate to TFS2010 without losing the history. I believe there are 2 ways, correct me if I'm wrong: installing a fresh tfs2010 and importing the DB from TFS 2008 or in-place upgrade. What is your recommendation and why? Are there any issue I should be prepared to face? Any advice is welcome.

  • ASP.NET Unit Testing - WatiN and Windows 7 / Internet Explorer 8

    - by tyndall
    Any tricks in getting WatiN to run on Win7/IE8? My code: browser = new IE(); browser.GoTo("http://testserver"); browser.TextField(Find.ByName("txtUser")).TypeText("tyndall"); The third line never really runs and I get an error back: System.Runtime.InteropServices.COMException : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) The second line seems to run. IE8 appears and is navigated to the correct URL.

  • Speed up UIPageViewController

    - by Jack Humphries
    I have a UIPageViewController with several pages. Each page is the same view controller, but the page number is kept track of and the correct page of a PDF is shown. The problem is that each PDF page needs to be loaded and drawn before the curl effect works (you slide your finger across the screen and nothing happens until loaded). Any ideas on how to speed this up or preload the next page? Thanks for your help.

  • Silverlight 4 RichTextbox Paragraph Margin or similar?

    - by Nacho
    Hi All, I'm trying to add bullets to the SL4 RichTextBox. Using the Run / Paragraph objects and adding the correct bullet child seems to be an easy approach. However, when I want to apply a bullet to an existing paragraph, I would like to indent the content of the paragraph. How can apply this kind of styling to the paragraph? The margin doesn't exist for the SL version of Paragraph. Thanks.

  • System.Data.SQLite parameterized queries with multiple values?

    - by Rezzie
    I am trying to do run a bulk deletion using parameterized queries. Currently, I have the following code: pendingDeletions = new SQLiteCommand(@"DELETE FROM [centres] WHERE [name] = $name", conn); foreach (string name in selected) pendingDeletions.Parameters.AddWithValue("$name", centre.Name); pendingDeletions.ExecuteNonQuery(); However, the value of the parameter seems to be overwritten each time and I end up just removing the last centre. What is the correct way to execute a parameterized query with a list of values?

  • iPhone MapKit problems: viewForAnnotation inconsistently setting pinColor?

    - by blackkettle
    Hi, I'm trying setup a map that displays different pin colors depending on the type/class of the location in question. I know this is a pretty common thing to do, but I'm having trouble getting the viewForAnnotation delegate to consistently update/set the pin color. I have a showThisLocation function that basically cycles through a list of AddressAnnotations and then based on the annotation class (bus stop, hospital, etc.) I set an if( myClass == 1){ [defaults setObject:@"1" forKey:@"currPinColor"]; [defaults synchronize]; NSLog(@"Should be %@!", [defaults objectForKey:@"currPinColor"]); } else if( myClass ==2 ){ [defaults setObject:@"2" forKey:@"currPinColor"]; [defaults synchronize]; NSLog(@"Should be %@!", [defaults objectForKey:@"currPinColor"]); } [_mapView addAnnotation:myCurrentAnnotation]; then my viewForAnnotation delegate looks like this, - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation { if( annotation == mapView.userLocation ){ return nil; } NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; MKPinAnnotationView *annView = nil; annView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:@"currentloc"]; if( annView == nil ){ annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; } annView.pinColor = [defaults integerForKey:@"currPinColor"]; NSLog(@"Pin color: %d", [defaults integerForKey:@"currPinColor"]); annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } The problem is that, although the NSLog statements in the "if" block always confirm that the color has been set, the delegate sometimes but not always ends up with the correct color. I've also noticed that what generally happens is that the first search for a new location will set all pins to the last color in the "if" block, but search for the same location again will set the pins to the correct color. I suspect I am not supposed to usen NSUserDefaults in this way, but I also tried to create my own subclass for MKAnnotation which included an additional property "currentPinColor", and while this allowed me to set the "currentPinColor", when I tried to access the "currentPinColor from the delegate method, the compiler complained that it didn't know anything about "currentPinColor in connection with MKAnnotation. Fair enough I guess, but then I tried to revise the delegate method, - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation instead of the default - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation at which point the compiler complained that it didn't know anything about the protocol for MyCustomMKAnnotation in this delegate context. What is the proper way to set the delegate method and/or MyCustomMKAnnotation, or what is the appropriate way to achieve consistent pinColor settings. I'm just about out of ideas for things to try here.

  • Using PartCover 2.3 with .NET 4.0 runtime?

    - by Roger Lipscombe
    I've successfully got PartCover 2.3 working with VS 2008 on my 64-bit machine. I'm now trying to get it to work with VS 2010 and NUnit 2.5.3. I've got NUnit using the correct CLR version, but I can't get PartCover to produce any output. All I get is an "empty" report XML file: <PartCoverReport date="2010-03-30T16:09:05.1009099+01:00" /> How do I get PartCover 2.3 (or 2.2, I guess) to work with NUnit 2.5.3 on .NET 4.0?

  • JNI, cast between jobect and jthrowable

    - by Dewfy
    Dear colleagues, I need raise an exception from C++ code. Raised exception must contain text and code of error. So common form: ThrowNew(jclass clazz, const char *msg) is not applicable. That is why I want create my own instance of java class: public class MyException extends Exception that contains one more property for code. But JNI interface has only declaration for Throw(jthrowable obj) Is it correct to cast instance of MyException to jthrowable ?

    Hi, I am trying to do the following 33.33333333333333/100.0 to get 0.333333333333333 however when I run System.out.println(33.33333333333333/100.0); I get 0.33333333333333326 as the output, similarly when I run System.out.println(33.33333333333333/1000.0); I get 0.033333333333333326 as the output. Does anyone know why, and how I can get the correct value (without loss of decimal places). Thanks
