pass-tomb VS OpenKeychain

By itself, Passwordstore will not encrypt file names or directory names, which might not be a problem if no one else has access to the machine that hosts your git repo, but if that's not the case (even if it's a private repo on whatever platform), you might want to use either Tomb or git-crypt-remote to have full end-to-end encryption. There are even some tools that glue tomb and pass together (https://github.com/roddhjav/pass-tomb for one), though I'm not sure what's the situation is like when it comes to mobile integration with tomb/git-crypt-remote.

That can of course be fixed by using pass-tomb, but that isn’t implemented in mobile clients (at least not on iOS).

A plug-in called pass-tomb exists to fix this, but doesn’t work with mobile apps (a least not iOS)

In addition to my PC set up I am also using the Android Password Store in combination with OpenKeyChain. Everything works fine except that decrypting any password simply works without requiring my PIN. I've tried both USB C connection and NFC and neither interface requires the PIN.

OpenKeychain is an Android app for doing some basic GPG related work. It can verify signatures (hidden in the "encrypt/decrypt" menu)

Also it integrates i.e. with K-9 mail to sign and verify.

OpenKeychain https://www.openkeychain.org/ integrates with multiple apps for encrypting your mail, plain texts, backups, xmpp chats.

I don't know what features you are looking for in encryption software but OpenKeychain is foss, audited and works just fine if you just want basic encryption/decryption/signing.

OpenKeychain: Easy PGP (version 5.8.0): Encrypt your Files and Communications. Compatible with the OpenPGP Standard.

I use mailbox.org with the encrypted inbox, Mozilla Thunderbird on desktop, and FairEmail + OpenKeychain on Android. I think StartMail is the only other one of those four options that supports standard IMAP and SMTP.

On Android OpenKeychain, TermBot, and K-9 Mail, are awesome.

I would try openpgp, you can use https://www.gpg4win.org/ on windows and https://github.com/open-keychain/open-keychain (not actively developed, if someone knows a good alternative please comment) for android.
