Hash multiple files with progress via PowerShell - plus drag 'n' drop support.

I am a free-minded and passionate software engineer, tech enthusiast and maker from Aachen.

In my bachelor thesis from 2018, I examined how well Ethereum can be integrated into existing business processes of the FH Aachen. By the start of 2020, I extensively explored the data science field and got fascinated by machine learning projects that improve human interaction. I recently completed my Master of Engineering in Information Systems Engineering where I took a deep dive into the emerging field of Reciprocal Recommender Systems (RRS) from a research and practical point of view. Bringing these views together, you can now fully read my thesis online and experiment with Chaos, a first of its kind framework – with the goal to enrich the RRS landscape with novel approaches for connecting humans.

After graduating, I have worked at gridX, a smart grid company which aims to make sustainable energy more accessible to everyone. Recently, I travelled through South East Asia to experience the various cultures, learn and reflect from a professional and private perspective. I am now offering software engineering services to companies that strive to have a positive impact on our world. Interested? Drop me a message!

In my free time, I am developing open-source software projects, transforming ideas to their physical representation by 3D printing, tinkering with electronic stuff and more! I love the idea behind free software and I use Arch, btw.

powhash's Issues

Error when only one Hash algorithm is selected

Implement --check option Unix-compatible output format

BLOCKED BY: #3

Also see https://help.ubuntu.com/community/HowToSHA256SUM to achieve a similar usability.

Implement output in Unix-compatible hash utility format for validation

Utilities such as sha256sum allow the validation of .<algorithm> (e.g. .sha256sum) files. These would be very useful as well as an export format as well as implementing a mechanism to validate existing files.

Example of output format:

Example argument in other command line applications (such as sha256sum):

  -c, --check          read SHA256 sums from the FILEs and check them

File-progress will not work when another PowerShell instance is opened (v1.0a)

This is one of the reasons why the script is in test phase:

When a PowerShell instance already exists, the progress for the current file will not work (the user realizes this error when the file-progress doesn't show up).
As a workaround, the progress for the current file will be disabled for the active script (line 208) when an error occurs 5 times while reading the counter data (line 183). A warning shows up then (line 210).

The exceptions thrown by Get-Counter typically read as "Invalid counter data" (I need to check it again for the exact wording).

Theoretically, this error should not occur - the _Get-ProcessCounterByPID function gets the counter PID-based, just as the name says.
