Create write-only keys for Backblaze B2
As far as I remember, you can’t create a write-only key via Backblaze’s dashboard without also giving read access to the key. I want to use this specifically for uploaders in servers, so, if compromized, an attacker can’t read data out of the bucket. $ curl https://api.backblazeb2.com/b2api/v2/b2_authorize_account -u "MASTER_KEY_ID:MASTER_KEY_SECRET" { "apiUrl": "https://api003.backblazeb2.com", "authorizationToken": ".....", } Replace apiUrl and authorizationToken in the next command: $ curl https://$apiUrl/b2api/v2/b2_create_key -d '{"capabilities": ["listBuckets","writeFiles"],"keyName":"key-name","accountId":"MASTER_KEY_ID"}' -H 'Authorization: $authorizationToken' { "accountId": "0f0f0f0f0f0f", "applicationKey": "K....", "applicationKeyId": "00....", "bucketId": null, "capabilities": [ "listBuckets", "writeFiles" ], "expirationTimestamp": null, "keyName": "key-name", "namePrefix": null, "options": [ "s3" ] } That’s all. ...
