AutoCrypt is a file encryption app for Mac from Ecleti, the developer formerly known as Tension Software. Its approach is document-based: instead of re-entering settings every time, you save an AutoCrypt document that records which files to encrypt, where the results go and which options to use. That makes it well suited to repeated jobs, such as encrypting a fresh batch of documents every night, using strong AES encryption protected by your password.

Key Features

• Encrypt and decrypt lists of files using the same saved document
• Strong AES encryption, with Blowfish kept for compatibility with older files
• Batch mode with an Autorun option for unattended, scheduled jobs
• Documents store all settings, so repeated encryption is a one-click task
• Built with current macOS technologies, including sandboxing and Dark Mode support

How to Download

1. Check that your Mac runs a recent version of macOS.
2. Use the green Download button on this page, or visit the developer Ecleti's website to get the current release directly from them.
3. Install AutoCrypt, create your first document with a short test list of files, and confirm you can decrypt them before trusting it with originals.

System Requirements

AutoCrypt is a native Mac app that runs on a recent version of macOS, on Intel and Apple silicon Macs. It is lightweight, and the storage you need depends on the size of the files you encrypt, since encrypted copies are written alongside your workflow.

FAQs

What happens if I forget the password?

The files cannot be opened without the correct password; that is the point of encryption. Keep the password somewhere safe and separate from the encrypted files.

Can AutoCrypt run automatically?

Yes. A document with the Autorun option enabled can be launched to process its file list without manual steps, which suits overnight batch jobs.
