Secret scanning using trufflehog

Trufflehog is a tool that can scan multiple sources (filesystem, git, have a pre commit hook, Postman), integrate in CI / Docker environment, etc... .

Easy start :

In the directory, with a docker daemon started

docker run --rm -it -v "${PWD}:/pwd" trufflesecurity/trufflehog filesystem /pwd

you will have a report with unverified result (probable issue), and confirmed issue.

CAP

CAP is a .NET library that implements the Outbox pattern. When working with distributed messaging systems like RabbitMQ or Kafka, we frequently face the challenge of ensuring that database updates and event publications are performed atomically. CAP addresses this challenge by recording the intent to publish the event in the same database transaction that caused the event. We find CAP to be quite useful as it supports several databases and messaging platforms while guaranteeing at-least-once delivery.

As a reminder, you can find more infos about the Outbox pattern in the following links:

Mockoon

Mockoon is an open-source API mocking tool. It has an intuitive interface, customizable routes and dynamic responses as well as the ability to automate the creation of mock data sets. Mockoon is compatible with OpenAPI and lets you generate different scenarios that can be tested locally and integrated with a development pipeline. You can also create "partial mocks" by intercepting the requests and only faking the calls that are defined in Mockoon. The partial mocks help simulate specific API routes or endpoints and forward other requests to actual servers. While partial mocks can be useful in certain scenarios, there is a risk of overuse, which may lead to unnecessary complexity. Besides that, Mockoon remains a valuable tool for quickly setting up mock APIs as well as improving and automating development workflows.

DevBox

Despite advances in development tooling, maintaining consistent local development environments remains a challenge for many teams. Onboarding new engineers often entails running commands or custom scripts that can fail unpredictably across different machines and result in inconsistencies. To solve this challenge, our teams have increasingly relied on Devbox. Devbox is a command-line tool that provides an approachable interface for creating reproducible, per-project local development environments, leveraging the Nix package manager without using virtual machines or containers. It has notably streamlined their onboarding workflow because once it has been configured for a codebase, it takes one CLI command (devbox shell) to reproduce the defined environment on a new device. Devbox supports shell hooks, custom scripts and devcontainer.json generation for integration with VSCode.

Troubleshoot test in vscode

Antoine — Sun, 25 Aug 2024 18:27:37 +0000

Troubleshooting

Testing in Visual Studio Code is a streamlined process that can enhance your development workflow. However, sometimes tests may not appear as expected. If this occurs, restarting OmniSharp can often resolve the issue (F1 + Command "Restart Omnisharp
"). OmniSharp is an integral part of the C# extension for Visual Studio Code, providing a comprehensive development experience, including features such as intelligent code completion (IntelliSense), debugging, and more.

Restarting OmniSharp
If your tests are not showing up in Visual Studio Code, try restarting OmniSharp. Here's how:

Open the Command Palette with Ctrl+Shift+P.
Type OmniSharp: Restart OmniSharp.
Hit Enter, and wait for OmniSharp to reload.

Command Line

When specific tests need to be run, the command line can be a powerful ally. Utilizing the "dotnet test --filter" command allows for running selective tests that match a given expression. This is particularly useful in large projects where running every test is time-consuming.

Using Command Line Filters
To run a subset of tests, use the dotnet test --filter command. For instance, if you want to run tests that contain the word "Login":

dotnet test --filter "FullyQualifiedName~Login"

This command will run all tests with "Login" in their fully qualified name.

Debug test

For a deeper dive into test issues, setting the environment variable VSTEST_HOST_DEBUG=1 triggers a debug prompt before the test host starts, as detailed in the Visual Studio Test Platform documentation. This allows developers to attach a debugger to the test host process, providing insight into the test execution and facilitating a more thorough investigation of any underlying issues.

Debugging Test Platform Components
For debugging, set the VSTEST_HOST_DEBUG=1 environment variable. When you run your tests, a prompt will appear to attach a debugger. Here's how to set the variable in Windows:

Open Command Prompt as an administrator.
Type set VSTEST_HOST_DEBUG=1 and press Enter.
Run your tests in the same Command Prompt session.

Incorporating these practices into your testing routine can significantly improve efficiency and ensure a robust codebase. Remember, a well-tested application is a cornerstone of software reliability and user trust.

Create Invite on Azure B2C with Graph API

While reading this great post from Damien Bod, i had the idea to do the same for inviting users in Azure B2C.

Configure Permissions in Azure

Following the doc, we require the following:

permission User.Invite.All (permission type : Application) and grant Admin Consent

Get from your application:

your tenant ID
your Application ID
a Secret Value

Code

Once you have configured the permission, you can use the following code (with you IDs / Secret):

    string[] scopes = new string[1] { "https://graph.microsoft.com/.default"};
    var tenantId = "<YOUR_TENANT_ID>";

    // Values from app registration
    var clientId = "<YOUR_APPLICATION_ID>";
    var clientSecret = "<YOUR_SECRET>";

    var options = new TokenCredentialOptions
    {
        AuthorityHost = AzureAuthorityHosts.AzurePublicCloud,   
    };

    // https://docs.microsoft.com/dotnet/api/azure.identity.clientsecretcredential
    var clientSecretCredential = new ClientSecretCredential(
        tenantId, clientId, clientSecret, options);

    var _graphServiceClient = new GraphServiceClient(clientSecretCredential, scopes);


    var invitation = new Invitation()
    {
        InvitedUserEmailAddress= "<EMAIL>",
        InviteRedirectUrl ="<YOUR_APPLICATION_URL>",
        SendInvitationMessage = false,
    };

_graphServiceClient.Invitations.Request().AddAsync(invitation);

using the following NuGet packages :

How to fix a partition issue in a bacpac backup

Antoine — Thu, 16 Sep 2021 15:40:45 +0000

Photo by Emmanuel Ikwuegbu on Unsplash

In order to fix it, we need to perform 6 steps:

rename the .bacpac file to .zip extension
extract model.xml and origin.xml
open model.xml and change the entry

                <Entry>
                    <Element Type="SqlPartitionValue">
                        <Property Name="ExpressionScript">
                            <Value><![CDATA[NULL]]></Value>
                        </Property>
                    </Element>
                </Entry>

                <Entry>
                    <Element Type="SqlPartitionValue">
                        <Property Name="ExpressionScript">
                            <Value><![CDATA[CAST(NULL AS DATETIME2)]]></Value>
                        </Property>
                    </Element>
                </Entry>

Save, and compute the new checksum using Powershell cmdlet Get-FileHash:

Get-FileHash -Algorithm 256 model.xml

write the checksum in origin.xml to replace previous model.xml checksum
Put back files model.xml and origin.xml in zip

Hope it helps !

Reuse tfvars in Powershell

Antoine — Sun, 12 Sep 2021 19:01:50 +0000

Photo by Thought Catalog on Unsplash

To reuse data in Powershell set in tfvars, we just have to use the ConvertFrom-StringData cmdlet.

In order to remove some character (such as { or } ), we can use -replace .

That will give us

$file = Get-Content .\varfile.tfvars
$file = $file -replace "}", ""
$file = $file -replace "{", ""
$convert = $file | ConvertFrom-StringData

Hope this help !
