    Hi Arun,

     

    You can upload assets as private to restrict access to the original asset and only allow access to derived (transformed) versions of the asset. The original asset can be accessed only with a signed URL (The URL and the signature that you created).

    You can further restrict access to the derived asset by activating the Strict Transformations mode.

    You can read more about it here:

    a API não diz nada sobre isso. Ele mostra como gerar uma assinatura, mas como eu uso essa assinatura para fazer upload de meus arquivos? Onde eu uso essa chave? Essa assinatura não serve para restringir o upload de arquivos para a minha nuvem ou serve apenas para ser usada após o upload do usuário? Se minha assinatura puder ser usada apenas depois, será inútil, porque o usuário já fez o upload do arquivo.

    Translates to:
    the API doesn't say anything about it. It shows how to generate a signature, but how do I use that signature to upload my files? Where do I use this key? Does this subscription not serve to restrict the upload of files to my cloud or does it serve only to be used after the user uploads? If my signature can be used only later, it will be useless, because the user has already uploaded the file.

    Hi Antonio,

    Here is a KB article explaining how to perform signed upload using signatures.
    https://support.cloudinary.com/hc/en-us/articles/207885595-How-can-I-generate-the-signed-upload-payload-on-my-server-

    You can also look into the new course on Advanced Concepts. There are modules for signing both the upload and media library widgets. In addition, there is a server that does server side rendering of signed widgets and an index.html that uses client-side calls to APIs from the server.

    Let me know if this helps.

    Best regards,
    Jay
