Strong modern encryption based on XChaCha and Argon2id, and always secure by default. Docs

Finder, meet Algebraic.
Encrypt and decrypt files directly from Finder menus, or use shortcuts ⇧⌘E and ⇧⌘Y. Docs

Advanced file format.
The encrypted file format is designed for integrity, performance, & backwards compatibility. Specification

Progress windows & notifications.
Follow longer operations with smooth progress estimates and native system notifications.

Command line powers. New
