Decrypting images to QImage

[UKCitizen1423]

Hi All,

I've spent a more than a few hours on this so any help appreciated. I have a set of encrypted images using Botan library. What is the best approach to decrypt the images so they can be used to construct a QImage. Obviously decrypting to disk is not feasible for the obvious reason but Botan decrypt returns a QString. I'm struggling to get the Qstring to a QByteArray to use something like QImage::loadFromData(const QByteArray &data, const char *format = nullptr).

A link that sums up what I am trying to achieve in Qt is https://www.codeproject.com/Articles...ypting-To-Disk

I am using Qt <= 5.4 series from 5.2 to 5.4. Upgrading from 5.2 to 5.4 should all work OK AFAIU but beyond that I am going to hit the QWebkit to QWebEngine conversion tasks. [Upgrading will take time which is unfortunately limited]. Some new functions were introduced in 5.4 which I think simplified this, not sure.

A last question: Is QWebEngine now all stable across all platforms (at least Win 7+, *nix, OS X Sierra)

Thanks in advance folks!
