TAesWriteStream replacement

Since TAesWriteStream is no longer used in mormot2 (pure mormot2 mode), is there a replacement class or any pointers in how to write one?

BTW I'm trying to make encrypted TSynLog descendant and so idea is to chain streams as TSynZipCompressor->TAesWriteStream->TFileStream.

Re: TAesWriteStream replacement

This is a good idea.

The problem with the old TAesWriteStream is that it was not safe, since it was using the ECB mode (i.e. no chaining), which is to be avoided.
I will add a class able to use any of the AES modes, with optional IV setting, and proper password derivation.

I'm also interested in encrypted logs to prevent my competitors from understanding internal flow in application.
