Simple ISO verification hashing done on the client - #3189

@RMcNeely I am curious. Could you imagine showing a visual glimpse of the actual state of your POC?

I can add something to show progress but I'm not sure that the way it is written I can easily add a progress bar given that the APIs are async. I would need to rewrite the file read operation to use chunks but to my knowledge, there's no way to do chunking on the hash creation so at best you would have a progress bar for only one part of the workflow.

I think it would be simpler to add a message that changes with the different steps of the verification process. Something like:

1. Reading ISO file
2. Creating Hash
3. Other? Stringifiying the hash and comparing it to an expected value would both be very quick operations. I'm not sure thats worth displaying something for.
