-```apache

-
-**Important**: The secrets file should have restricted permissions (e.g., 0600) to prevent unauthorized access.

-# Webhook Authentication Migration Guide
-
-This guide helps Hydra administrators migrate from unauthenticated webhooks to authenticated webhooks to secure their Hydra instances against unauthorized job evaluations.
-
-## Why Migrate?
-
-Currently, Hydra's webhook endpoints (`/api/push-github` and `/api/push-gitea`) accept any POST request without authentication. This vulnerability allows:
-- Anyone to trigger expensive job evaluations
-- Potential denial of service through repeated requests
-- Manipulation of build timing and scheduling
-
-## Step-by-Step Migration for NixOS
-
-### 1. Create Webhook Configuration
-
-Create a webhook secrets configuration file with the generated secrets:
-
-```bash
-# Create the secrets configuration file with inline secret generation
-cat > /var/lib/hydra/secrets/webhook-secrets.conf <<EOF
-<github>
-  secret = $(openssl rand -hex 32)
-</github>
-<gitea>
-  secret = $(openssl rand -hex 32)
-</gitea>
-EOF
-
-# Set secure permissions
-chmod 0440 /var/lib/hydra/secrets/webhook-secrets.conf
-chown hydra:hydra /var/lib/hydra/secrets/webhook-secrets.conf
-```
-
-**Important**: Save the generated secrets to configure them in GitHub/Gitea later. You can view them with:
-```bash
-cat /var/lib/hydra/secrets/webhook-secrets.conf
-```
-
-Then update your NixOS configuration to include the webhook configuration:
-
-```nix
-{
-  services.hydra-dev = {
-    enable = true;
-    hydraURL = "https://hydra.example.com";
-    notificationSender = "hydra@example.com";
-
-    extraConfig = ''
-      <webhooks>
-        Include /var/lib/hydra/secrets/webhook-secrets.conf
-      </webhooks>
-    '';
-  };
-}
-```
-
-For multiple secrets (useful for rotation or multiple environments), update your webhook-secrets.conf:
-
-```apache
-<github>
-  secret = your-github-webhook-secret-prod
-  secret = your-github-webhook-secret-staging
-</github>
-<gitea>
-  secret = your-gitea-webhook-secret
-</gitea>
-```
-
-### 2. Deploy Configuration
-
-Apply the NixOS configuration:
-
-```bash
-nixos-rebuild switch
-```
-
-This will automatically restart Hydra services with the new configuration.
-
-### 3. Verify Configuration
-
-Check Hydra's logs to ensure secrets were loaded successfully:
-
-```bash
-journalctl -u hydra-server | grep -i webhook
-```
-
-You should not see warnings about webhook authentication not being configured.
-
-### 4. Update Your Webhooks
-
-#### GitHub
-1. Navigate to your repository settings: `https://github.com/<owner>/<repo>/settings/hooks`
-2. Edit your existing Hydra webhook
-3. In the "Secret" field, paste the content of `/var/lib/hydra/secrets/github-webhook-secret`
-4. Click "Update webhook"
-5. GitHub will send a ping event to verify the configuration
-
-#### Gitea
-1. Navigate to your repository webhook settings
-2. Edit your existing Hydra webhook
-3. In the "Secret" field, paste the content of `/var/lib/hydra/secrets/gitea-webhook-secret`
-4. Click "Update Webhook"
-5. Use the "Test Delivery" button to verify the configuration
-
-### 5. Test the Configuration
-
-After updating each webhook:
-1. Make a test commit to trigger the webhook
-2. Check Hydra's logs for successful authentication
-3. Verify the evaluation was triggered in Hydra's web interface
-
-## Troubleshooting
-
-### 401 Unauthorized Errors
-
-If webhooks start failing with 401 errors:
-- Verify the secret in the Git forge matches the file content exactly
-- Check file permissions: `ls -la /var/lib/hydra/secrets/`
-- Ensure no extra whitespace in secret files
-- Check Hydra logs for specific error messages
-
-### Webhook Still Unauthenticated
-
-If you see warnings about unauthenticated webhooks after configuration:
-- Verify the configuration syntax in your NixOS module
-- Ensure the NixOS configuration was successfully applied
-- Check that the webhook-secrets.conf file exists and is readable by the Hydra user
-- Verify the Include path is correct in your hydra.conf
-- Check the syntax of your webhook-secrets.conf file
-
-### Testing Without Git Forge
-
-You can test webhook authentication using curl:
-
-```bash
-# Read the secret
-SECRET=$(cat /var/lib/hydra/secrets/github-webhook-secret)
-
-# Create test payload
-PAYLOAD='{"ref":"refs/heads/main","repository":{"clone_url":"https://github.com/test/repo.git"}}'
-
-# Calculate signature
-SIGNATURE="sha256=$(echo -n "$PAYLOAD" | openssl dgst -sha256 -hmac "$SECRET" | cut -d' ' -f2)"
-
-# Send authenticated request
-curl -X POST https://your-hydra/api/push-github \
-  -H "Content-Type: application/json" \
-  -H "X-Hub-Signature-256: $SIGNATURE" \
-  -d "$PAYLOAD"
-```
-
-For Gitea (no prefix in signature):
-```bash
-# Read the secret
-SECRET=$(cat /var/lib/hydra/secrets/gitea-webhook-secret)
-
-# Create test payload
-PAYLOAD='{"ref":"refs/heads/main","repository":{"clone_url":"https://gitea.example.com/test/repo.git"}}'
-
-# Calculate signature
-SIGNATURE=$(echo -n "$PAYLOAD" | openssl dgst -sha256 -hmac "$SECRET" | cut -d' ' -f2)

-# Send authenticated request

 Hydra can be notified by github or gitea with webhooks to trigger a new evaluation when a

-## Webhook Authentication
-
-Hydra supports webhook signature verification for both GitHub and Gitea using HMAC-SHA256. This ensures that webhook
-requests are coming from your configured Git forge and haven't been tampered with.
-
-### Configuring Webhook Authentication
-
-1. **Create webhook configuration**: Generate and store webhook secrets securely:
-   ```bash
-   # Create directory and generate secrets in one step
-   mkdir -p /var/lib/hydra/secrets
-   cat > /var/lib/hydra/secrets/webhook-secrets.conf <<EOF
-   <github>
-     secret = $(openssl rand -hex 32)
-   </github>
-   <gitea>
-     secret = $(openssl rand -hex 32)
-   </gitea>
-   EOF
-
-   # Set secure permissions
-   chmod 0600 /var/lib/hydra/secrets/webhook-secrets.conf
-   chown hydra:hydra /var/lib/hydra/secrets/webhook-secrets.conf
-   ```
-
-2. **Configure Hydra**: Add the following to your `hydra.conf`:
-   ```apache
-   <webhooks>
-     Include /var/lib/hydra/secrets/webhook-secrets.conf
-   </webhooks>
-   ```
-
-3. **Configure your Git forge**: View the generated secrets and configure them in GitHub/Gitea:
-   ```bash
-   grep "secret =" /var/lib/hydra/secrets/webhook-secrets.conf
-   ```
-
-### Multiple Secrets Support
-
-Hydra supports configuring multiple secrets for each platform, which is useful for:
-- Zero-downtime secret rotation
-- Supporting multiple environments (production/staging)
-- Gradual migration of webhooks
-
-To configure multiple secrets, use array syntax:
-```apache
-<github>
-  secret = current-webhook-secret
-  secret = previous-webhook-secret
-</github>
-```

-=head1 NAME
-
-Perl::Critic::Policy::Hydra::ProhibitShellInvokingSystemCalls - Prohibit shell-invoking system() and exec() calls
-
-=head1 DESCRIPTION
-
-This policy prohibits the use of C<system()> and C<exec()> functions when called with a single string argument,
-which invokes the shell and is vulnerable to injection attacks.
-
-The list form (e.g., C<system('ls', '-la')>) is allowed as it executes directly without shell interpretation.
-For better error handling and output capture, consider using C<IPC::Run3>.
-
-=head1 CONFIGURATION
-
-This Policy is not configurable except for the standard options.
