- WebCrypto keyring (PBKDF2 600k + AES-GCM master key) and per-note/per-image keys - Encrypt/decrypt commands convert the note and its own images, deleting the originals - Unlock, setup and change-password dialogs; manual lock; lock on page close - Encrypted images are decrypted to blob URLs; pasted images are encrypted before upload - Rewrite image links in the browser when renaming an encrypted note - Skip local drafts for encrypted notes and confirm before closing with unsaved changes - Show encrypted notes as locked with an explanation outside secure contexts
