HashGen - Hash Generator & Comparator, from lern-digital.de, is a compact Chrome extension built to create and compare cryptographic hashes inside the browser for secure verification. The extension produces MD5, SHA-1, SHA-256 and SHA-512 hashes from text and includes a quick comparator for matching hash strings without leaving the device. It stores settings and results locally, offers multi-language support, and targets developers, security professionals, and privacy-minded users needing an offline integrity tool.

HashGen serves as a focused, single-purpose integrity tool for technical users

HashGen is designed specifically to generate and compare cryptographic digests from text, not as a general-purpose cryptography suite. The extension supports MD5, SHA-1, SHA-256 and SHA-512 generation and provides a comparator that checks whether two hash strings match, making it suitable for quick verification tasks and manual testing workflows where a lightweight browser-based utility is preferred.

Installation size and architecture favour minimal overhead

The extension installs at approximately 19 KiB and describes a lightweight architecture, which keeps the add-on small in the browser profile. That compact footprint reduces extension list clutter and avoids feature bloat; however, HashGen is not intended for batch hashing or automated pipelines since it focuses on immediate, interactive use rather than background processing or scripting hooks.

All processing stays on the device, reducing exposure to external services

HashGen runs its hash calculations entirely within the browser and does not upload input to external servers, a design that reduces the risk of sensitive strings leaving the machine. The developer implements a zero-tracking approach with no analytics or third-party SDKs, and settings and results persist locally between sessions so data remains stored only in the browser profile.

Browser integration and workflow fit favour Chromium-based, manual workflows

The extension is available for Chrome and other Chromium-based browsers, so it fits users who already work in that ecosystem. It offers multi-language support across several European languages and requires no account or API keys, which simplifies immediate use. The trade-off is limited integration: there is no cloud sync, no file-hashing interface mentioned, and no automation hooks for CI-style workflows.

HashGen is a practical, low-friction utility for focused verification tasks

HashGen is a practical choice for developers and security-minded users who need a compact browser tool for on-the-spot integrity checks. Its narrow scope keeps the interface simple but means it is not a substitute for automated or cloud-integrated hashing workflows. Users who prioritise small, predictable browser utilities for manual verification will find it a dependable, low-overhead option.
