Comment sécuriser l'API PDF dans Docker en utilisant C#

Docker Features

• Portability: Containers run on any platform without modification, from development machines to production environments.
• Isolation: Each container operates independently, preventing interference between applications and their dependencies.
• Efficiency: Sharing the host system's kernel, containers are lightweight compared to virtual machines.
• Easy Deployment: Docker speeds up application deployment with minimal setup, facilitating continuous integration and delivery (CI/CD).

Components of Docker

• Docker Engine: The backbone of Docker, managing container build, run, and management.
• Docker Images: Read-only templates for creating containers, including application code, runtime environments, and dependencies.
• Docker Container: A runtime instance of a Docker image.
• Docker Hub: Cloud-based storage for sharing and publishing Docker images.

Docker plays a key role in modern DevOps cycles by ensuring predictability and speed in application deployment.

Installing and Running IronSecureDoc

Pull the IronSecureDoc Docker image from the GitHub repository using the following command:

# Pull the IronSecureDoc Docker image
docker pull ironsoftwareofficial/ironsecuredoc

# Pull the IronSecureDoc Docker image
docker pull ironsoftwareofficial/ironsecuredoc

After pulling the Docker image, start IronSecureDoc with this command:

# Run IronSecureDoc in a Docker container with specified environment variables
docker container run --rm -p 8080:8080 -e IronSecureDoc_LicenseKey=<IRONSECUREDOC_LICENSE_KEY> -e ENVIRONMENT=Development -e HTTP_PORTS=8080 ironsoftwareofficial/ironsecuredoc:latest

# Run IronSecureDoc in a Docker container with specified environment variables
docker container run --rm -p 8080:8080 -e IronSecureDoc_LicenseKey=<IRONSECUREDOC_LICENSE_KEY> -e ENVIRONMENT=Development -e HTTP_PORTS=8080 ironsoftwareofficial/ironsecuredoc:latest

Adding Password to a PDF Document

The REST API of IronSecureDoc is a modern, web-based interface enabling developers to safely interact with the software's document management and PDF processing features. Utilizing RESTful principles, this API offers a simple way to integrate IronSecureDoc functions into applications, regardless of technology stack.

For password encryption of a PDF document, you can post a request to the IronSecureDoc API as follows:

# Use curl to encrypt a PDF document with a user password
curl -X 'POST' \
  'http://localhost:8080/v1/document-services/pdfs/encrypt?user_password=demo' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@test.pdf;type=application/pdf'

# Use curl to encrypt a PDF document with a user password
curl -X 'POST' \
  'http://localhost:8080/v1/document-services/pdfs/encrypt?user_password=demo' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@test.pdf;type=application/pdf'

This command encrypts and securely stores the PDF document.

Signing a PDF Document

Here's a sample code to digitally sign a PDF using a certificate:

# Use curl to digitally certify a PDF document
curl -X POST 'http://localhost:8080/v1/document-services/pdfs/certify' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@Demo.pdf;type=application/pdf' \
  -F 'certificate_file=@DemoSign.pfx;type=application/x-pkcs12' \
  -F 'certificate_password="p4ssw0rd"' \
  -F 'certificate_permissions=1'

# Use curl to digitally certify a PDF document
curl -X POST 'http://localhost:8080/v1/document-services/pdfs/certify' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@Demo.pdf;type=application/pdf' \
  -F 'certificate_file=@DemoSign.pfx;type=application/x-pkcs12' \
  -F 'certificate_password="p4ssw0rd"' \
  -F 'certificate_permissions=1'

This command processes the PDF, uses the certificate to sign it, and saves the output as certify.pdf.
