How did you manage to get the upload PIN? @russellmoya

@russellmoya you can download uploaded file by ObjectMetadata and decode msg (where contains encoded contacted user id) from the records list and token (where contains encoded user id who uploaded data). But your token is empty and it seems you are avoided getToken process.

Thanks a lot @rinekri for answer me.
i remove the token , but in the original code , i have the token . @rinekri .
i have Encryption secret key , that i store in google cloud secret manager .

@russellmoya you can use decryptTempID and validateToken functions to do this. You can find them in the existing files: first / second. For encryptionKey parameter use await getEncryptionKey()

i modify getUploadToken.ts file .
in the getUploadToken.ts , i change if (data) code .
the new code :

if (data) {
//const uploadCodes = await retrieveUploadCodes();
const uploadCodes = uid.substring(0, 6).toUpperCase();
console.log('getUploadToken:', obtained ${uploadCodes.length} upload codes);
console.log("voici le code de retrive",uploadCodes);

if(uploadCodes.length >0){
    if(uploadCodes === data.toUpperCase()){
      valid = true ;
    } else {
        valid = false ;
    }
}

// valid = uploadCodes.find(x => x === data) !== undefined;
console.log('getUploadToken:', data is ${valid ? 'valid' : 'not valid'} code);
}

for msg i use descyptTempID and for token i use validateToken ? ... @rinekri

@rinekri yeah. This is an example how you can download uploaded data to decrypt it:

async function getCurrentUploadedData(event: ObjectMetadata): Promise<UploadedData> {
  return admin.storage().bucket(event.bucket).file(event.name!).download().then(file => {
    const uploadedData = JSON.parse(file[0].toString())
    console.log('getUploadedData:', `Uploaded data token: ${uploadedData.token}`);
    return uploadedData
  }).catch(function (error) {
    console.log("getUploadedData", error);
    return null
  })
}

interface UploadedData {
  records: Record[];
  token: string
}

interface Record {
  id: string,
  msg: string,
  timestamp: string
}
