Files can be stored at their exact size: a third padding choice, off, in the account's size-hiding setting and as `nmts padding off`.
The standard rule stays the default. Choosing the exact size shows the file's length to the network and to anyone who reads the blob, and uses about 1 % less storage; the sentence beside the option says so. The recovery tool reads such files unchanged.
The CLI can list and revoke API keys: `nmts key list` and `nmts key revoke <id|all>`, with the NMTS key, never with a key.
Until now a key could only be seen or cut in a browser. Both commands present the NMTS key's proof, judged the way a sign-in is, and a key is refused on purpose: a key that could list or cut keys would hand whoever stole it the whole automation. Revoking asks once at the terminal; in an auto mode it takes --yes.
