signature

SO I am testing a Rest OAuth implementation. My testing tool will send the HTTP Request, but I need to prepare the Authorization header. What I need: I want a valid Authorization Header What I have: All the headers except the oauth_signature I also have the 2 secrets, the token_secret and the consumer_secret. I also posses the access_token. So It really boils down to, having to sign this request. How do I do that? Summary : I simply need to populate the oauth_signature portion of the Authorization header for a RESTful service. How do I do it? Basically: oAuthHeader="OAuth"; oAuthHeader

Ok, so i've googled around, i've found threads here on stackoverflow and i've checked the official Facebook wiki and.. and what not.. I now hope that one of you guys sits on a Facebook API sample code for Python. This is what i've got so far and all i get is "Invalid Signature" via PyFacebook which appears to be a dead project: from facebook import Facebook api_key = '123456789______' secret = '<proper secret key>' OTK = 'XXXXX' # <-- You get this from: https://www.facebook.com/code_gen.php?v=1.0&api_key=123456789______ long_term_key = None fb = Facebook(api_key, secret) def generate_session

I have a application in which i am getting sign from the user with finger it works fine but i want that signature should be converted into image and should display in imageview here is the code for my signature coding. Signature is working fine and it shows on the view but i want to convert those graphics line into image and display in imageview. #import <UIKit/UIKit.h> @interface MyLineDrawingView : UIView { UIBezierPath *myPath; UIColor *brushPattern; } @end Implementation Classs #import "MyLineDrawingView.h" @implementation MyLineDrawingView - (id)initWithFrame:(CGRect)frame { self = [super

I've two pdf documents certified (signed and validated with the same mechanism based on Itext 7 ) and when i use adobe reader DC to check their validity, only one has the green mark. the good one: https://1drv.ms/b/s!AkF6t4TavwMvgxWaidlUqvPvHH1r the bad one: https://1drv.ms/b/s!AkF6t4TavwMvgxQCMdGY61S1EvUh Regards David L This is not an Adobe bug, it's a feature. (And an iText bug) When Adobe performs the cryptographic validation, it will also perform additional checks to see if a signature was attacked or not. It analyses several suspects and if that analysis turns out negative, Adobe will

We're using iText to put a text inside a signature placeholder in a PDF. We use a code snippet similar to this to define the Signature Appearence PdfStamper stp = PdfStamper.createSignature(inputReader, os, '\0', tempFile2, true); sap = stp.getSignatureAppearance(); sap.setVisibleSignature(placeholder); sap.setRenderingMode(PdfSignatureAppearance.RenderingMode.DESCRIPTION); sap.setCertificationLevel(PdfSignatureAppearance.NOT_CERTIFIED); Calendar cal = Calendar.getInstance(); sap.setSignDate(cal); sap.setLayer2Text(text+"\n"+cal.getTime().toString()); sap.setReason(text+"\n"+cal.getTime()

I will try to answer both, please correct me if I am wrong: Where: If a static method is being called using Classname .method() or using reflection then it doesn’t matter even if you change the return type of the calling method, the same method will still be called. So JVM probably checks this in one of the native methods of jvm.cpp methodHandle m (THREAD, init_klass->find_method(vmSymbols::object_initializer_name(),> vmSymbols:: void_method_signature() )); if (m.is_null()) { ------ THROW_MSG_0 ……….. Why: Although its useless to return a value from main, as java does not do anything with it

Have found a function address in a DLL. Have no source code for this DLL, not mine. This DLL is not really changed frequently, but when changed, it is a problem for me to find it by disassembling. Saw some notes in web about making it signature and then find it by this saved signature. Can you, please, give some ideas or working example on how to implement this? You can achieve this by code signature scanning, which is something I have done in the past. The concept mainly works by relying on the fact that functions often do not change too much between updates, but simply relocate because they

I would like to call a method from an dll, but i don't have the source neither the header file. I tried to use the dumpbin /exports to see the name of the method, but i can found the methods signature? Is there any way to call this method? Thanks, It is possible to figure out a C function signature by analysing beginnig of its disassembly. The function arguments will be on the stack and the function will do some "pops" to read them in reverse order. You will not find the argument names, but you should be able to find out their number and the types. Things may get more difficult with return
