Using Algebraic

Encrypting an item

You can encrypt items directly from Finder or by using the Algebraic app.

Finder: Control-click or right-click on the item. Choose “Encrypt in Algebraic” from the menu. Some users may need to choose “Services > Encrypt in Algebraic”.
Finder: Select items and use keyboard shortcut + Shift + E.
Algebraic: Drag and drop items onto Algebraic’s main window. Click “Encrypt Items”.
Algebraic: Choose “File > Encrypt” from the menu, or use + E.

Decrypting an item

You can decrypt items directly from Finder, by using the Algebraic app, or by dropping the items onto Algebraic’s Dock icon.

Finder: Control-click or right-click on the item. Choose “Decrypt in Algebraic” from the menu. (Some users may need to choose “Services > Decrypt in Algebraic”.)
Finder: Select items and use keyboard shortcut + Shift + Y.
Finder: Simply open (e.g., double-click) the encrypted algebraic file.
Algebraic: Drag and drop items onto Algebraic’s main window. Click “Decrypt Items”.
Algebraic: Choose “File > Decrypt” from the menu, or use + Y.
Dock: Drag encrypted algebraic files onto the Dock icon.

Checking for updates

To check for updates, choose “Algebraic > Check for Updates” from the Algebraic menu.

You may enable or disable automatic updates in Algebraic’s Preferences window.


Common questions (and answers)

Q: What kinds of files can Algebraic encrypt?

A: Algebraic can encrypt nearly any file you throw at it. Algebraic works with PDFs, Pages documents, videos, photos, MP3s, plain text files, binaries, or anything really — it has no restrictions related to file types and file extensions. Algebraic also encrypts folders; it does so by encrypting each item inside the folder.

From a Unix file system perspective, Algebraic can encrypt regular files, symbolic links, and directories. It does not encrypt sockets, named pipes, character device files, or block device files.

Q: Does Algebraic encrypt items in place?

A: Yes. During encryption, Algebraic removes the original, unencrypted item and replaces it with the encrypted version. This means that you don’t have to manually remove the unencrypted item after encryption is complete.

Q: Is Algebraic backwards compatible?

A: Yes, new versions of Algebraic can always encrypt and decrypt items created using a previous version of Algebraic.

Q: How does Algebraic encrypt aliases and shortcuts?

A: Algebraic encrypts the alias itself, not the destination of the alias.

Q: Do licenses expire?

Your license does not expire for the major version of Algebraic purchased. The current major version of Algebraic is version 1. Algebraic 2 may require a new license purchase, but your copy of Algebraic 1 will continue to work.

See Pricing & Licenses for more details.

Q: Does Algebraic work on other operating systems?

Algebraic currently only works on macOS (more specifically, macOS 11 or higher). An iPhone and iPad version of the app is planned.

There are currently no plans for a graphical application on other systems.
