I wrote the following email to Synology's support team, hoping it would make it back to someone with the ability to make something happen.
I am hoping others will also add their comments to this thread (hence keeping it alive) and possibly make their voice heard by emailing directly Synology's support team (feel free to copy and adapt my text below if needed). You can contact them by doing, in DSM: Start-->Support Center-->Contact Support.
Please don't forget to VOTE in the above poll, and hopefully get others to vote as well. You can additionally reply in this thread to keep it "alive" and hopefully it will get the attention of someone at Synology.
Edit: Here are additional links of people who are trying to do the same, either encrypt those "special folders", or simply encrypt the whole disks. I don't see how so many people voicing the same request could be ignored. See:Dear Synology,
Although I’ve been a big fan of your product for over 3 years, I’d like to formally ask that you add a crucial feature to the next version of DSM. In fact, I’d go as far as to say that without this simple addition, the most important new feature of your latest products (DS415+, DS1815+ and DS1515+) is almost useless. Indeed, one of the touted advantages of this new architecture is the performance for encrypting and decrypting files. It was about time. In today’s world (Hello Mr. NSA) I think that we cannot have too much encryption – it should even be the de facto standard (Thank you, Android 5.0). This addition was enough to get me to replace my DS1511+ for the DS415+. It was also the nudge I needed to finally encrypt my important folders.... you know... the folder that is so dear to most of your customers – no, not the porn folder - that folder that no amount of money can replace if it is lost: THE PHOTO FOLDER!!!
Surprise (you know where this is going): I can’t encrypt the Photo (or video, or music or home) folders. WHAT?!? That’s crazy. Who’s idea was this? I’m no Kim Kardashian, and I doubt that the hackers are after my private pictures, yet there is a reasons why I spent thousands of dollars on Synology products to build my own private cloud, at home, and I refuse to upload personal data to Apple (and their friends at the NSA) or Google (and their friends at the NSA) or any other public cloud (and their friends at the NSA): I want to control the level of security for my data.
Hardware acceleration for encryption and decryption was great news, but the fact that those crucial folders cannot be encrypted is simply dumb. Sure, I could store my pictures under Photo 2/Music 2/Video 2 and encrypt those folders; but then my files wouldn’t be available in DS Photo / DS Audio / DS Video. Those apps are amongst the great features of your DSM system.. otherwise I might as well just do away without DSM and simply store my stuff on an external hard drive for much less money.
I’m sure there is more to this issue than meets the eye... I suppose decrypting on the phone will be too demanding on the mobile device’s cpu. Sure, decrypting on the fly and streaming to DS Photo may not the most “secure” and elegant solution (although I have it setup to use HTTPS), but SOME security is better than NO security. Will this be a problem with DLNA devices? I don’t know. But allowing me to encrypt those folder will put my mind at ease in the unlikely event that my NAS is stolen.
Furthermore, and that’s the important part for myself, encrypting my Photo and Home folders will allow me to do offsite backup to a friend's Synology NAS, knowing that he won't have access to them. At the moment, there is no reasonable option to do offsite backup of those folders to a system that I am not the only one with Admin rights.
As it turns out, if you have been monitoring your own forum, you’ll see that I am not the only one wanting this feature. Take a look at the following threads (some go back as far as 2010!!!), that all relate to the above problem, and the many users who have commented on them. Imagine how many have not commented or even didn’t purchase a Synology product upon realizing this limitation:

I would appreciate it if this message would make it back to the product management/development team.
