Swift Data Tool

It has a lot kinds of hashes and supports iterative hashing and hash salting also it gives a good AES encryption and decryption tools that supports multiple key sizes

Lots of features packed into a quick, easy to use UI. I found it to work best with an accompanying lesson plan or instruction tutorial on hashes and encryption in general. Once you get the hang of it, I would expect it could be pretty fun.

Edited: Thanks for the quick turnaround time. Now the app is fully functional and it js great. —— Unable to read what I am typing at first because the app uses black text on a black background. Great idea and functionality, but the execution needs work. ETA: Turned off Dark Mode and can confirm that is the issue. Not sure how often this is updated, but adding support will quickly net a 5-star upgrade.
