TWRP now supports for Qualcomm encryption for 1+1 topic

Great news for encrypters, since Qualcomm's hardware-based encryption provides much quicker read-write speeds than AOSP’s software method.

In an announcement on Google+ earlier today, developer Ethan Yonker (Dees Troy) explained that Qualcomm encryption generally offers better performance than ‘stock’ Android encryption, making this a welcome addition to the custom recovery platform.

But there is a caveat:

Quote:

If you didn’t encrypt using CM 12.0 nightly on or after 16th of January 2015, you probably aren’t getting the performance benefits of Qualcomm’s encryption. It also appears that the Oxygen OS team did not add support for Qualcomm encryption. If performance matters to you but you need to be encrypted, then I’d suggest sticking with CM.

So, no-go with OxygenOS, and if you've been encrypted and dirty flashing CM12 since before 1/16/2015, you have do full wipes, reinstall and re-encrypt.
