Mask values in .env files with asterisks until you focus (place the cursor on) a given line. Helpful while screen sharing or pairing to avoid accidental secret exposure or screenshots.
Features
Automatically masks value portions of lines like KEY=VALUE in *.env and .env.* files.
Unmasks a line while the cursor/selection is on it (re-masks after a short delay when leaving the line).
Hover tooltip (configurable) can reveal the real value without unmasking inline.
Status bar lock icon to toggle masking on/off globally.
Delay before a previously focused line is re-masked.
Security & Limitations
This is a visual masking aid only. Secrets remain in the file on disk and in the editor buffer; other extensions, git, search, or screen capture outside VS Code can still access them.
Copying a masked selection will still copy the real value (because the underlying text is unchanged).
Large values are truncated to 32 asterisks visually; the hover shows up to 200 characters.
