How to enable encryption?

Hello everyone!
I am wondering how to enable encryption of my P9 Lite running Nougat B370. My phone is rooted, bootloader unlocked and TWRP installed, if that is relevant.
In the menus I don't find any option to encrypt my phone. So, anyone knows if it is possible?

If you mean data encryption, it is already encrypted.

You sure about that? Because TWRP can access my data partition without pin...
Is there any way to check whether disk encryption is truly enabled?

It's encrypted unless you unencrypted it with twrp but the latest update of twrp (nouget) lets you backup data unlike twrp on MM.

It's strange though, I've never unencrypted my phone with twrp. But when I boot into twrp my whole data partition is open for access without any sort of password/pin. Seems to me there is no encryption active.

TWRP can mount data partition, but it does not mean that it is able to decrypt it.
It can backup/restore or format it which is what usually what a TWRP do, if you install a custom ROM like LOS you will need to format it because the system can't decrypt it while stock ROM can do it.

What I meant by my post is not only that twrp can mount the data partition. I can also access all my files within said data partition.

moto g4 plus rooted encrypted with password but twrp not ask for that

i encrypted my phone after i root it. It's running Lineageos. Encryption works, but if i boot in recovery i can enter folders but don't see any data. I can not mount data folder or add/install anything. Looks logic because it's encrypted, but i read somewhere that twrp will ask for a password when system is encrypted. I don't get this message.
Any suggestion how i need to do it correct? that i can enter twrp with pass

AFAIK you need a recovery that supports encryption.

i have twrp 3.2.1-0, question, how to start the ask password in terminal or recovery mode, if it is possible?

The only recovery i know which does support encryption is the 32 Bit shreps recovery. Do keep in mind that if you encrypt your device and use that recovery you won't be able to flash 64 bit roms since no 64 bit recovery supports encryption

Mi A1 Forced Encryption

I'm sorry if this is posted again but I can't find anything about my problem.
My Mi A1 in unrooted.
I had installed gcam without rooting it to continue receiving OTA, after the latest update I wanted to disable gcam. During the process the application unlocked the bootloader but didnt lock it again.
When I disabled it after the reboot my phone did a factory reset and enrypted itself. I want to decrypt my phone so I used some ways I found on the internet like:
Simple factory reset.
Locked bootloader.
Factory reset again, even though after the lock it did it itself.
Flashed fastboot stock rom.
Flashed twrp read only, wiped system and flashed fastoboot stock rom again!
Still the phone forced encrypt itself after every way I tried:
For gcam I used this way: https://forum.xda-developers.com/mi-a1/how-to/tool-google-camera-root-magisk-enable-t3747585
I didn't check the thread because I already had the app to do the installation.
For fastboot installation I used this: https://forum.xda-developers.com/mi-a1/how-to/ota-official-fastboot-image-n2g47h-7-12-t3728929
EDIT: What if I unlock the bootloader with MiUnlock and relock it via fastboot?

Phone is encrypted by default. Why would you want to have it decrypted? But if you insist.. you have to install magisk, disable forced encryption and reformat data partition in TWRP.

Locking or unlocking the bootloader after May update wipes your data, this is normal for Android and now our phones.
Encryption is default, it would have been encrypted before the wipe as it is now after the wipe, why do you want it unencrypted?

Thank you very much, I never experienced this again after unlocking so I thought it was because of the encrypt, I hadn't checked if it was encrypted before the wipe and I assumed it wasn't.

I didn't know the phone was encrypted by default.
Thank you for the possible way though.

Yeah, it is encrypted by default and hw encryption is used. So don't think that it can affect your performance in any way.

After reformatting data partition, do I need to do anything else?

Keep Magisk installed, otherwise it will probably get encrypted again by stock boot image. Not sure, I didn't try it.. I want my data secure.

Rooting my X00_TD?

I have unlocked the boot-loader and also installed TWRP recovery on my X00_TD device which has 'Pie' as it's Stock ROM.
Now, I would like to know how to proceed to do rooting on this device.
Is it necessary to run decrypt zip file before we run 'magisk-v19.1' to root?
Please advise!

Decrypt removes another variable from the process, so yeah it might be good to remove a probable failure point.

Decrypt and then Magisk?

So , irrespective of the state of the device one needs to flash the decrypt file first and then flash the magisk to root the device, right?
Please advise!

When rooting mine I used the decrypt.zip . When you factory reset the phone will take some time to encrypt your data and this prevents that. It will hinder you from flashing stuff from the internal storage in TWRP. You can use magisk without it too.

Unable to Mount Storage?

I went ahead and flashed magisk without flashing decrypt. The root was successful!
Now, when tried to clear cache via TWRP it says 'Unable to Mount Storage'. What could be the reason here?
Is it safe to wipe dalvik/art cache?
Please advise!

Try to run decrypt.zip it should fix the problem. I used a OTG device since I didn't have a SD card. Unless you run decrypt.zip you cannot use the internal storage. So I would recommend running it despite my last statement.

Decrypt mi 9t global/eea

Hello everyone,
How I can decrypt mi 9t with global/eea ROM?
Which recovery I have to use?
And what steps should I do?
Thanks

Simply remove your lockscreen security. Once you done tbat, encryption is gone. However, if you factory reset while you still had encryption (lock screen security) you have no other alternative than wiping your internal storage.

Youre wrong. If You remove lockscreen security Your data is still encrypted. You can check it in Settings,Addatoonal Settings,privacy,encrypt phone.
Only way to remove it is format data but beckup Your data first to computer or USB drive otg.

I'm currently using the 4pda twrp and formating Data does NOT decrypt the Partition for some reason. I even got the xiaomi.eu and havocOS working in encrypted Mode before. Ist there anything I am Missing / can decryption bei done manually? I dont want to run into problems later on.
