Frequently Asked Questions

  • 1. What is Secure Hash Generator?

    Secure Hash Generator is a browser add-on that helps you easily generate secure hash codes (i.e. checksum) for any file or text. Simply open the extension UI by clicking on the toolbar button. Add your files via the file selector window or by drag and drop to the designated area. If you do not have any file, please add a text in the text area (top right corner). Once the input is ready (either file or text), please select an encryption method. Currently, there are 8 methods available to choose from. The first 4 are from the native HTML5 API and the rest are from CryptoJS open-source JavaScript API. To get more info about HTML5 API please visit this page and for CryptoJS engine please visit this GitHub page. By default, SHA-256 is chosen as the hashing method in the extension when it is first added to the browser. Please click on the - Generate - button to make hash code for the input file(s). All the generated items are listed in a table within the UI and stored in the local browser memory. Each item has a Copy, Download, and Remove button. Moreover, you can download all items at once by clicking on the green - Save - button next to the generate button. Likewise, to remove all items please click on the green - Remove - button in the app.

  • 2. How can I work with this add-on?

    As mentioned above, simply open the app UI, then drag and drop desired files in the designated areas (top-left corner). You can also upload your file into the app via the file selector tool. Then select a hashing method and finally click on the generate button. Please note that for large files the HTML5 API has a better performance comparing to the CryptoJS engine and this is because the HTML5 engine works natively in the browser. The only downside for the HTML5 API is, it does not support a wide variety of hashing algorithms. Therefore, for some methods, such as MD5, you need to use the CryptoJS API. This engine is an open-source JavaScript API that has been around for a while and is improved a lot over time. It supports almost all hashing methods and has a relatively good performance.

  • 3. How can I download the source code for Secure Hash Generator?

    To download the source code for this extension from Chrome Web Store, it is recommended to use Extension Source Downloader. With this addon, you can download the source code as a ZIP or CRX format to your machine. If you want to download the source code from the Firefox addons store, please open the firefox download link (if available) in the Firefox browser and then right-click on the - Add to Firefox - button and select - Save Link As... - item. Choose the destination folder on your machine and then save the file in XPI format. You can then rename the XPI format to a RAR or ZIP file. Some extensions may have a GitHub repo address, which you can use to download the source code as well. But, it may not be the latest version of the addon. Therefore, downloading the source code from the official web stores is the best option as it always gives you the latest version of the addon.

  • 4. How does Secure Hash Generator addon work?

    This addon uses two different JavaScript encryption APIs. One is called SubtleCrypto and built into all modern browsers (Firefox, Chrome, Edge, and Opera). The other one is called CryptoJS and is a famous third-party engine that supports a wide variety of hashing techniques. It is important to note that all the generated hash codes are stored in the local browser memory. Therefore when you reload the app, you can see all the codes and related filenames. To clear the storage, please click on the green - Remove - button next to the - Generate - button.

  • 5. Can I encrypt multiple files with this addon?

    Yes, you can drag and drop all your files in the app UI (top left corner) and then click on the generate button. The extension loops through all the files and generates hash code for each and displays them in a table.

  • 6. How do I turn the extension OFF?

    When app UI is closed, this addon is completely OFF and has no usage (RAM/CPU) at all. Alternatively, if you want to completely turn off the addon, please head to the extensions tab in your browser and then click on the disable button from there.

  • 9. How can I download a hash code?

    There is a download button for each hash item in the extension UI. Please click on this button to download the hash code as a text file to your system. If you want to download all hash codes at once, please click on the green download button next to the generate button. Likewise, to clean the hash table please click on the green remove button.

  • 10. How can I change the download path?

  • 11. How is the performance of this addon?

    According to our tests, this addon has a very good performance (when using native HTML5 SubtleCrypto) comparing to other hashing apps. In fact, the speed is almost identical to other native hashing applications. For the CryptoJS engine, the performance is also acceptable as this library is considered an advanced choice for all hashing and encryption tasks.
