digital-signature

I am attempting to run my app in an emulator and have been receiving the following error: Installation failed since the APK was either not signed, or signed incorrectly. If this is a Gradle-based project, then make sure the signing configuration is specified in the Gradle build script. I am attempting to run the app with a debug setting so signing the app should not be necessary as it will be given a temporary signature upon building. This happens often when you install the same app generated on a different computer. Even the unsigned apk has a signature, so your phone is confused why you're

I've got a passthrough NDIS intermediate driver, consisting of two .inf files (one standard and one miniport) and a .sys file. Because of the Windows 7 driver signing requirements, I had to get a code-signing certificate and sign the .sys file in order for the driver to install on a 64-bit system. This works fine, and I have many successful Windows 7 installs. However, the same installer fails on the Windows 8 Consumer Preview (64-bit). If I boot with Windows Signature Enforcement turned off, it installs correctly, so it's definitely a signature issue. What new requirements were added between

Pardon Me! I am poor in java. Please Correct me wherever I am wrong and improve wherever I am poor! I am trying to digitally sign a dynamically created pdf using PDFBox with the following program: Tasks in the Program: (i) Creating Template PDF (ii) Updating ByteRange, xref, startxref (iii) Constructing Original Document for Signature Creation (iv) Creating Detached Enveloped Digital Signature (v) Constructing Digitally Signed PDF Document by concatenating Original Doc Part - I, Detached Signature and Original PDF Part - II Observations: (i) pdfFileOutputStream.write(documentOutputStream

This is a followup question to question 1072540, 'WinVerifyTrust to check for a specific signature?' . I want to write a C++ function Lets call it TrustedByUs of the form: bool TrustedByUs(std::string pathToBinary, std::string pathToPublicKey) The idea is that we give this function a path to a binary .dll or .exe file that has been signed with a digital signature. The pathToPublicKey string is the path to a public key of our particular signing certificate. Using the code in http://support.microsoft.com/kb/323809 it's pretty straight forward to verify that the pathToBinary file is in fact

Is it possible to generate PDF file in PHP with digital signature? An open-source solution is preferred. TCPDF starting from version 5.5.001 (released 2010-06-23) can sign generated PDF documents. It can also place transparent signature rectangle field over any bitmap/text, so clicking on the signature field brings up signature panel - cool feature. That same does seta-PDF signer, however you have to pay:-) If TCPDF extended with FPDI bridge, it can also parse already existing documents with PDF version up to 1.7 and sign it with X.509 certificate. It can 100% parse PDF documents generated by

I have some security key in an application. I want to store it securly. I like to store it in a native shared library (maybe generated from some code). After that I want it to be returned by a method that will check the signature of the original APK. So no one can use this file except trusted applications. I know, that ndk library could be also decompiled, but this is even harder to make reverse engineering of native code then java .class files. Question: Is there a way to calk the signature of the origin apk from the native code (c/c++)? How can I make sure that the library is called from the
