Implementation

The App has three main functionalities:

1. Upload User uploads a file of any format into the form and gets the hash of a file as a response. The file itself is uploaded to the server store/ab/abcdef12345..., where "abcdef12345..." - name of a file (its hash). /ab/ - subfolder which is the first two letters from hash.
2. Download User enters file name (its hash) into the form. In case the system finds the file with such name user gets this file downloaded. Otherwise, the app returns 404.
3. Delete User enters file name (its hash) into the form. In case the system finds the file with such name files is deleted from server. Otherwise, the app returns 404.

Tools

flask is used for implementation. hashlib lib is used for getting hash by md5 algorithm.
