I ran bundle update rails and got this. I'm stumped. If activerecord-session_store 2.0 depends on a version of actionpack between 5.2.4.1 and above, and if actionpack is a dependency of Rails 6, shouldn't this be ok?

My app encrypts and uploads certain files, and then makes them visible to admins. To achieve the latter functionality, my encryption gem's documentation suggests a controller action that looks like this:
...ANSWER
Answered 2020-Dec-20 at 10:12Simply said: I think you're not quite doing this in the way Shrine intends and there's multiple ways to remedy this. I'll rank them from (in my opinion, based on complexity/appropriateness) best to worst:
- Encryption could/should be treated as a part of Shrine's processing/derivatives concept. So you'd want to perform the processing there and set the metadata accordingly. The Shrine author himself has outlined solutions to process the original file in a thread here: https://discourse.shrinerb.com/t/keep-original-file-after-processing/50.
- You can override metadata manually: https://shrinerb.com/docs/metadata#controlling-extraction. This would probably mean not using attribute based assignment but instead calling the attacher directly (see below).
- You can define your own MIME type determining logic as set out here: https://shrinerb.com/docs/plugins/determine_mime_type.
- You're using
Shrine.mime_typealready. Use the value you get from this and store it in a separate database columnmime_typeon yourid_docsmodel and then use it when you're reading from the database. Note that this probably implicitly means that the value in this column and the value you get from the file's metadata's mime type are out of sync.
Using the attacher directly:
QUESTION
I have a Delphi 10.4 program with a clientdataset, loading XML files users choose with OpenFile dialog. It works just fine and depending on the contents of the XML, the fielddef structure is set automatically.
Now I want to be able to read Decrypted files and with ClientDataSet.SaveToFile, save Encrypted files.
Currently I'm using Lockbox 3.7 to Decrypt the chosen file, creating a temp file, which is then read by loadfromfile. Likewise Savetofile writes data back to a temp file, which is then encrypted and given it's chosen name. It works very well, but leaves the temp file on disk. And even if I delete the temp file in code, it's relatively easy to recover it, if you know how. So the security with Encryption like this, is not so high after all.
I would want to be able to perform the decryption directly in LoadFromFile (and similar encryption at SaveToFile) as a fileEn(or De)Crypt function, as suggested by the subject, without the use of temp files, but haven't been able to find any useful functions.
Do anybody know of such function ? If so, please point me in the right direction. The last couple of days I've been using google to search for something useful, but it has left me more confused and lost, than I feel I was before.
An alternative solution where the temp files created by the LockBox EnCryptFile (and DeCryptFile) are completely destroyed, to a point where no recovery is possible, would do as a temporary solution, so pointers to ways to destroy a file completely, would also be welcome.
Thanks in advance for any help I can get.
...ANSWER
Answered 2020-Dec-10 at 14:17Use ClientDataSet.LoadFromStream instead of LoadFromFile. I'm sure LockBox has a function to decrypt into a TStream. Use a TMemoryStream to avoid storing decrypted data to disk.
Likewise, write the client dataset to a stream (SaveToStream), use a TMemoryStream and it will stay in memory. Then encrypt it and save the result to disk.
QUESTION
is there a way or a library to encrypt/decrypt values with AES-256 mode GCM in Delphi? as it seems that most libraries do not support it like DCPcrypt or LockBox.
or maybe there is a Windows API that could handle that.
thanks in advance.

I have a Patient model backed by a patients Postgres database table. It has an attribute national_id that is encrypted by the lockbox gem and therefore stored in the national_id_ciphertext column. This attribute is saved/updated fine and I can verify this in the database.
However when I read this record back, the national_id attribute is not included.

Answered 2020-Sep-27 at 13:57As you noted in your own test, the value is available. national_id is an available method on the object but is not a DB attribute. You can always retrieve it with dot notation e.g. my_patient.national_id but not through hash notation

Install lockbox
You can use lockbox like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
