I'm not familiar with how it works: while part of it seems standard as it uses dm-crypt, another part (the dm-crypt parameters) seem to be custom. Because of that, as far as I know, it's not possible to open an encrypted data partition in GNU/Linux with standard tools like cryptsetup, so you probably need custom tools for that. As for changing the password, there is an f-droid application that claims to be able to do that[1]. I didn't try it yet though. Note that I didn't complete any review of f-droid applications for potential freedom issues yet[2]. > If this is modifiable from a built system, where would I need to > look?

References: ----------- [1]https://f-droid.org/en/packages/com.kibab.android.EncPassChanger/ [2]I'm unsure if it's possible to build the same exact same apk (minus the signatures) from a GNU/Linux distribution that complies with The FSF/GNU's Free System Distribution Guidelines (FSDG).
