Cybersecurity & Ethical HackingObjective-CAGPL-3.0

Abstract

Strongbox is an open-source Cybersecurity & Ethical Hacking project. A KeePass/Password Safe Client for iOS and OS X. Strongbox supports the well-known, portable and open Password Safe (version 3) and KeePass file formats (KeePass 1 and 2, i.e. KDB, KDBX (3.1 and 4)). It is built using Objective-C. The complete source code is publicly available on GitHub under the GNU Affero General Public License v3.0, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction

Strongbox supports the well-known, portable and open Password Safe (version 3) and KeePass file formats (KeePass 1 and 2, i.e. KDB, KDBX (3.1 and 4)). Strongbox uses encryption algoritms likes TwoFish, Argon2d, ChaCha20, Aes, Salsa20 and various other cryptographic techniques (SHA256s, HMACs, CSPRNGs) to store groups and entries, containing various secrets, mostly designed around password storage. You can also store file attachments in KeePass format safes. YubiKey is also supported.
