external-ca | Hyperledger Fabric setup using External CA as Root CA | TLS library

I'm writing an app that contains a file explorer. I'd like this file explorer that I wrote be able to provide files for other apps, similar to how some android file explorers work. I've written the provider part in the manifest:

I'm downloading an apk from s3 and storing it in a directory named SAMPLE_APK. When I try to execute the apk present in the directory, I get an error.

I am trying to send a list of files using tcp socket but i get this file provider error. please help if anyone can. Thanks

I am sharing the app with the file provider and I want to share the image from the bitmap. I have two file providers number one is for share apk, number two for share image. apk file provider works good but the image share file provider not sharing images. if I share an image to WhatsApp, Gmail it says file format does not support it.

fileprovider.xml

trying to get file(PDF) form internal storage to upload on server with the help of Android ResultLauncher API, getting Uri in result but I am unable to read that Uri. When trying to copy that file to my app's scope directory with the help of result Uri, getting permission error on contentResolver.openInputStream(uri). this is the error:

I'm having difficulty simply renaming a file created by the app but was put into the documents folder.

EDIT:

As it so happens the videos are not created by the application but are expected to be renamed by the application. The user drops the videos into the documents folder manually at the start. My mistake.

Here is my code:

I have create simple Pdf page, saving it to internal app dir and trying to open it with Intent. PDF viewer doesn't show any content, but when I copy the file to download dir and open it manually everything works.

I am learning how to install and use EJBCA to deploy an enterprise PKI. I know I can install EJBCA using a quick install configuring the script ejbca-setup like is explained here, and I also have tested a longer install process with WildFly 10 like explained here. In both variants I need to create a default ManagementCA and I can make some configuration changes related to the database I'm using and other things during the installation process. My problem is I need to install a CA of subCA type, and my subCA private key comes in a PKCS12 or PEM file from the root CA (I'm not completelly sure about the format yet).

Right now I know I can install EJBCA with the default CA and then create my subCA as a second one like is explained here, but I want to know if I can create this subCA as my first CA at the installation process, because I dont't need the default CA. Also if I have to create the default CA mandatorily I want to know if I can remove this default CA after I create my subCA without problems or if this first default CA is some kind of special CA for EJBCA.

I am trying to delete images taken through the Camera api and, in principle it does delete them from my application folder but the images are still in the DCIM/camera folder.

I am using an ITOS device with Android version 9.

Here is the code I am using.
