Encryption Interface crashing Firebird process when working on big db file
(6.7GB)
----------------------------------------------------------------------------------
Key: CORE-5830
URL: http://tracker.firebirdsql.org/browse/CORE-5830
Project: Firebird Core
Issue Type: Bug
Components: API / Client Library
Affects Versions: 3.0.3
Environment: Windows 10 x64
Reporter: Daniel Mazur
Priority: Critical
I have written encryption plugin, it works fine but yesterday it break up the
file. As first I thought that this is issue with encryption length etc. I have
checked my code and it still encrypting/decrypting other databases except one
which got 6.7 GB size. I decided to check the original code written by Mr.
Peshkov (cryptDB.pas) from FB directory it still crashing the firebird
process. So my conclusion is that Firebird can't handle encryption on Big
Files. The same DB file was encrypted severe times before but got less size
(around 6GB) and it works fine.
I wish I could share with this big db file but it cointains secret company data
(clients info etc.) so maybe recreating big db file with random data may lead
to recreate bug on another environment
