encpass.sh VS OpenKeychain

https://github.com/plyint/encpass.sh/archive/v${pkgver}/${pkgname}-${pkgver}.tar.gz

The difficulties mentioned in the article with passing secrets on the command line is one of the reasons why we wrote encpass.sh (https://github.com/plyint/encpass.sh). We had a similar need for a lightweight solution for managing secrets for simple shell scripts on our local workstations and in restricted environments. Bonus, it can be easily customized with extension scripts to adapt functions for your own specific needs. See our keybase extension for an example -> https://github.com/plyint/encpass.sh/blob/master/extensions/...

We made an extension for encpass.sh that stores secrets in Keybase (https://github.com/plyint/encpass.sh/blob/master/extensions/...) if that sort of thing is of interest to you. Outside of personal secrets, it can be used as a sort of low cost stand in for shared secrets that you might use something like Vault for in a team environment.

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.
