Expunger

Have you ever wanted to temporarily hide some sensitive data? Or maybe you want to collapse text into single symbol, or modify source file before the AI assistant reads it? Well, now you can. This extension does just that. You can choose a secure master password for encryption of replaced data, or leave as is if you trust the users.

Features

• Replaces selected text with ordered placeholders such as [PLACEHOLDER:1], <EXPUNGED-2>, etc.
• Stores replaced text in a per-file storage record in extension folder.
• Encrypts stored text with AES-256-GCM using the master key.
• Allows text restoration of whole files or single placeholder.
• Synchronizes changes to file name with storage if interacting through VS Code.

Commands

• Expunger: Replace Selection With Placeholder
• Expunger: Restore Placeholders In File
• Expunger: Set Secure Session Key
• Expunger: Clear Secure Session Key
• Expunger: Show Security Status
• Expunger: Replace/Restore At Cursor
• Expunger: Reindex Placeholders In File

Shortcut:

• Ctrl+Alt+R (Cmd+Alt+R on macOS): replace selected text, or replace back when the cursor is on a placeholder.
