 **[VeraCrypt](https://www.veracrypt.fr)** | VeraCrypt is open source cross-platform disk encryption software. You can use it to either encrypt a specific file or directory, or an entire disk or partition.

VeraCrypt is the successor of (the now deprecated) TrueCrypt.
 **[Cryptomator](https://cryptomator.org)** | Open source client-side encryption for cloud files - Cryptomator is geared towards using alongside cloud-backup solutions, and hence preserves individual file structure, so that they can be uploaded.

 [AES Crypt](https://www.aescrypt.com/) is a light-weight and easy file encryption utility. It includes applications for Windows, Mac OS, BSD and Linux, all of which can be interacted with either through the GUI, CLI or programatically though an API (available for Java, C, C# and Python). Although it is well established, with an overall positive reputation, there have been some [security issues](https://www.reddit.com/r/privacytoolsIO/comments/b7riov/aes_crypt_security_audit_1_serious_issue_found/) raised recently.
