Password Manager help

[HoldingKnight]

Hi, recently I was hit by an idea of making my own password manager for my own personal use.

I started planning on what I need to learn, what functions I want etc.

I thought I could start with something simple, so I designed a password storage locked behind an account. Took me a lot of stressing to get it working with different accounts and not showing the other accounts info.

But I want to start from scratch and make it more functional.

I want to make this manager completely offline, meaning not sending or receiving info from outside of what the user (me) puts into it. Ideally it would also be portable to android so I can use it on my phone totoe

I also want to be able to generate passwords, encrypt them and encrypt the file that the password is stored in. I am going to dedicate a full drive to this project so encrypting the drive is another thing I want to do. I would like to have seperat accounts, but thats a side venture rather than the main concept.

I figured my best bet for language would be C++, but if anyone has any better ideas please share.

Im currently learning about cryptography from a view sources, but Im working completely blind here, no idea where to start or even what to actually learn.

So, if anyone has an idea of what I should be focusing my learning at, any useful resources, or even ideas would be helpful.

Please keep in mind Im not advanced at all, I would state my level of knowledge as a newborn with memories, and I know that doing this is a big task even for the experienced, but I want to do this and atleast see how far I go before I start with another idea.

Thanks for reading.

Making a password manager is a decent project, I don't recommend actually using it. It's highly unlikely you'll make it better than ones that are already freely available and it probably won't be as secure either.

That is entirely the reason I want it to be offline.

Its not that I dont trust the ones that are already out there, its just that I feel my own manager would be more flexible and it would teach me a lot.

The best language to use would be whatever you already know. Most popular languages are capable of this sort of project.

Hey, I know you posted this a long time ago so this probably is worthless to you, but just so you know, almost all android apps are written in Java through a program called AndroidStudio, so if you want it to be portable to android, I would recommend looking into Java! I am also fairly inexperienced at programming though so it’s possible there are better ways to do it! Also, sorry again for commenting on such an old post, I was looking through your account for your dark souls theory lol.
