Hay,
I need help with this task. Every time I uploud the task I get 0/100. I wondering what are you uploading? Please help me because I don’t know how to pass that.

Thanks in advance

Check if you get the same hash when you do the operation manually. Also make sure you use Trim to remove spaces from the start and end of your text before you generate the hash.
