Replace text inputs with proper selectors for Agent advanced hashcat configuration

[unclesp1d3r]

Problem

Currently, the Agent creation/edit form uses plain text inputs for advanced hashcat configuration options like opencl_devices and backend_device. This approach has several issues:

• Poor UX: Users must manually enter comma-separated integers without guidance
• Error-prone: No validation of valid values at input time
• Lack of discoverability: Users don't know what values are valid without consulting hashcat documentation
• Inconsistent with best practices: Modern forms should use appropriate input types for constrained value sets

Current Implementation

File: app/views/agents/_form.html.erb

The form currently uses:

<%= a.input :backend_device,
            hint: "Backend devices to use, separated with commas, leave blank to let hashcat decide" %>
<%= a.input :opencl_devices,
            hint: "OpenCL device types to use, integers separated with commas, leave blank to let hashcat decide" %>

Model: app/models/advanced_configuration.rb

• Both fields are stored as strings
• Values are comma-separated lists of integers

Proposed Solution

1. OpenCL Devices Field

Replace the text input with a multi-select checkbox group or dropdown multi-select.

Valid options (per hashcat documentation):

• 1 - CPU
• 2 - GPU
• 3 - FPGA, DSP, Co-Processor

Implementation:

• Use collection_check_boxes or similar to render checkboxes for each device type
• Convert selected values to comma-separated string on save
• Parse comma-separated string to checked values on load

2. Backend Device Field

This field is context-dependent - it should show devices that the agent has reported during initial configuration.

Proposed approach:

• For new agents: Keep as text input (agent hasn't configured yet) OR hide the field entirely until first check-in
• For existing agents: Display a checkbox list of all devices known for that specific agent (from the devices array attribute)
• Convert selections to comma-separated list of device indices
• Add helper text explaining that device indices correspond to the order in the Capabilities tab

3. Additional Improvements

• Add form validation to ensure only valid integers are submitted
• Consider adding a "Let hashcat decide" checkbox that clears the field when checked
• Update form hints to be more descriptive
• Add visual indicators showing which devices are selected

Implementation Checklist

• Update app/views/agents/_form.html.erb with new input types
• Add helper method to parse/serialize device selections
• Update form specs in spec/system/agents/create_agent_spec.rb
• Update page object spec/support/page_objects/agent_form_page.rb
• Add validation in AdvancedConfiguration model if needed
• Update API documentation in spec/swagger_helper.rb if format changes
• Test edge cases (no devices selected, invalid values, etc.)
