Connection to ELS for FastAPI Repository

This guide outlines the steps needed to integrate the TuxCare ELS for FastAPI repository.

Step 1: Get user credentials

You need a username and password in order to use TuxCare ELS for FastAPI repository. Anonymous access is disabled. To receive the credentials please contact sales@tuxcare.com.

Step 2: Set Up ELS for FastAPI

To use TuxCare's ELS for FastAPI, follow one of the options below:

Option 1: Install a Package with ELS Repository via Command Line

You can install or upgrade a package directly using the ELS repository with your credentials:

pip install --upgrade \
  -i https://<username>:<password>@nexus.repo.tuxcare.com/repository/els_python/simple \
  fastapi

Replace <username> and <password> with the credentials provided by sales.

Option 2: Configure `pip` to Use the ELS Repository (Full Replacement)

This method is recommended if you want to use only ELS-patched Python packages from TuxCare and replace the default PyPI source with the TuxCare ELS repository.

Create or update the pip configuration file and add the following:
```
[global]
index-url = https://username:password@nexus.repo.tuxcare.com/repository/els_python/simple
```
Run the command to install the latest package version:
```
pip install --upgrade fastapi
```
Or install a specific patched TuxCare version, for example:
```
pip install fastapi==0.63.0.post1+tuxcare
```

Option 3: Add the TuxCare ELS Repository as Additional (recommended)

If you want to keep using public PyPI and fetch only specific patched packages from TuxCare, use extra-index-url instead. In this configuration, make sure to specify the exact patched version (step 2 below), otherwise pip may install the version from public PyPI.

Create or update the pip configuration file and add the following:
```
[global]
extra-index-url = https://username:password@nexus.repo.tuxcare.com/repository/els_python/simple
```
Run the command to install a specific patched TuxCare version, for example:
```
pip install fastapi==0.63.0.post1+tuxcare
```

Upgrading to a Newer TuxCare Version

To upgrade to a newer TuxCare release (e.g., from version.post1+tuxcare to version.post2+tuxcare) use the same installation method you used above and specify the newer package version.

Vulnerability Exploitability eXchange (VEX)

VEX is a machine-readable format that tells you if a known vulnerability is actually exploitable in your product. It reduces false positives, helps prioritize real risks.

TuxCare provides VEX for FastAPI ELS versions: security.tuxcare.com/vex/cyclonedx/els_lang_python/fastapi/.
