A secure hash is used to authenticate access to a public URL. For example when a storage object visibility is set to 'secure' the URL will require a valid hash parameter. The hash parameter rotates every hour and is only valid for a few hours.
To generate a secure hash you will need to generate a MD5 checksum in the following format:
Replace apikey with the secret api key generated in your dashboard.
Replace yyyymmddhh with the current date and time 2023061820 - This would be for June 18th 2023 at 8pm UTC.
Replace string with the value to be hash. For storage objects this would be the name.
