Hello LeoW,
I hope you are doing great, I was looking for a reply where RSAF was mentioned, I’m not sure if you suggested it or it is someone else, anyway that reply was deleted for unknown reason, however I tried RSAF and unfortunately it didn’t work, the drive was indeed created but when i try to select the folder using obsidian, it says choose another folder that is not in root folder like in storage, I tried also Round Sync since RSAF is outdated and RS was a maintained fork, same result, I thought about making a Samba mount however since this took me much time i didn’t have the time to waste more time, I realized that you can’t setup a mounted virtual drive on Android on a non-rooted device due to Android-Security, I was then wondering let me see the available community plugins, i checked age encrypt, Meld Encrypt to encrypt partial data etc.. but again when you check the repo issues, you see people losing their data just by accident or by unintentional manipulation while trying to decrypt or encrypt it, the disclaimers also are explicitly makes it clear where you can use it on your own risk, so i came up with an idea which is very simple, I created an html page that has JS code, the code encrypts and decrypts your data, you enter what you want to encrypt like a password or the desired sensitive data then you add a passphrase and you get an encrypted hash, if i want to decrypt it i do the same in reverse, I put the html file in my phone home screen, once i needed to decrypt the data i copy paste then boom, my data is decrypted.
I recreated the syncthing folders since i have versioning of previous data that has older data in plain text, you can delete the .stfolder and re-create it.
If you want i can share the gitlab html code link or if anyone needs it, just ask, my code uses AES-256-GCM + PBKDF2 (100K iterations)
Thank you guys
