Despre această extensie

Enigma 2.0 lets you encrypt plain text into stylized Matrix emblems (Katakana characters and symbols) directly on any website — including social platforms like X (Twitter), forums, and messaging pages.

Share encrypted messages publicly. Only people who know the password can read them.

What you can do
• Encrypt a text selection or an entire page
• Decrypt a selection or an entire page
• Use the right-click context menu for quick access
• Display encrypted blocks in a distinctive green Matrix style
• Enable optional auto-decrypt when pages load (if a password is saved)

How it works
1. Open the add-on popup and enter your password
2. Select text on any web page
3. Click "Encrypt selection" — your text is instantly transformed

To read encrypted content, enter the same password and choose "Decrypt selection" or "Decrypt page".

Security
• Client-side encryption using AES-GCM (256-bit) and PBKDF2 (SHA-256)
• A new salt and IV are generated for every encryption
• Your password never leaves your browser

Privacy
• No servers, no accounts, no analytics, no telemetry
• Password and settings are stored locally in Firefox only
• Text is modified only when you explicitly encrypt or decrypt

Good to know
Encrypted text remains visible on the page as characters (for example in posts or comments), but it is unreadable without the correct password. This makes Enigma 2.0 ideal for private notes in public spaces.

Comentarii de la dezvoltator

Encrypt / Decrypt selection – Much more reliable handling inside contenteditable areas (e.g. X/Twitter composer) and heavily fragmented DOM structures.
Partial text replacement – Fixed bug where mixed-language text (German + English) would only partially be replaced, leaving original text and encrypted matrix text visible at the same time.
Matrix span wrapper – The styled <span data-text-chiffrierer> is now fully removed on decryption instead of only replacing its content.
Context menu vs Popup – Consistent behavior between right-click context menu and popup buttons.
Race conditions during async crypto – Original selected text is now removed immediately before the (slow) PBKDF2 encryption completes.
Re-encrypt after decrypt – Now works reliably even after previous operations on complex sites like X.

Immediate deletion of selection + temporary marker technique for stable replacements.
Better detection and complete replacement of leftover matrix wrapper spans.
Extended protection logic (isExtensionNode) for temp markers and matrix elements.
Improved range handling when replacing inside contenteditable editors.

This release focuses on stability when working with selections on modern websites (especially X.com with its translation tool and mixed-language content).

Stable encrypt/decrypt selection on X and contenteditable sites. Fixed partial replacement bug with mixed-language text. Matrix wrappers are now cleanly removed. Better compatibility between popup and context menu.
