Cipher Type Planner

Additional questions:

Ask each of the following. If the engineer does not have an answer, accept "N/A" or "not yet decided" and note it as a gap in the plan.

• Import/export - Should import/export support be included in this plan?
• UI details - Are there specific UI requirements for the form or view sections (e.g., dropdowns, masked fields, copy buttons)?
• Subtitle - What value should the subTitle getter on the view model return? This appears in vault list items.
• Icon - What icon represents this type in the vault? Bitwarden uses bwi- icon classes.
• Organization policy - Does this type appear in the restricted item types policy UI?

Step 2: Enter Plan Mode

After gathering requirements, enter plan mode using EnterPlanMode. Explore the codebase to verify current patterns and file locations. Use the SshKey cipher type (value 5) as the canonical reference for implementation patterns.

Key files to inspect for patterns:

• libs/common/src/vault/enums/cipher-type.ts - Enum definition
• libs/common/src/vault/models/api/ssh-key.api.ts - API model pattern
• libs/common/src/vault/models/data/ssh-key.data.ts - Data model pattern
• libs/common/src/vault/models/domain/ssh-key.ts - Domain model pattern
• libs/common/src/vault/models/view/ssh-key.view.ts - View model pattern
• libs/common/src/models/export/ssh-key.export.ts - Export model pattern
• libs/common/src/vault/models/domain/cipher.ts - Container switch patterns
• libs/vault/src/cipher-form/components/sshkey-section/ - Form component pattern
• libs/vault/src/cipher-view/sshkey-sections/ - View component pattern

Step 3: Build the Plan

Write a comprehensive plan to the plan file. The plan MUST include all sections below.

Plan Output Format

1. Overview

• Cipher type name:
• Integer value:
• Feature flag:
• Minimum client version:
• Fields: Table of all fields with name, type, encrypted (yes/no), required (yes/no)
• Supports autofill: Yes/No
• Supports linked fields: Yes/No

2. Clients - New Files to Create

List every file that needs to be created, with the full path and a brief description. Organize by
