OpenKeychain VS Cryptomator

https://issuetracker.google.com/issues/238257723 https://github.com/open-keychain/open-keychain/pull/2804

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.

the best way to do this is with https://cryptomator.org

Before putting anything on a cloud service I would recommend 3rd party tools, like Cryptomator, to encrypt folders and such, then upload to a cloud service.

I use Cryptomator - https://cryptomator.org

I've used countless encryption "schemes" over the years, from True/Vera-Crypt to encrypted sparse bundles/images, and none have ever really felt right.

These days i tend to use Cryptomator[0] instead. It accomplishes what none of the others could do, which is transparent encryption across devices.

With Cryptomator, i simply create a vault somewhere in the cloud, stuff data in it, and i can access it from my laptop, phone or tablet, and not think much about it. It integrates into the normal file browsing APIs, and doesn't get in the way.

Because it does "per file" encryption, it also doesn't need to download a 20-100MB chunk from the cloud before decrypting, so it's rather fast (depending on file size of course).

Cryptomator's arguably the most popular encryption software for cloud storage (you can give yourself zero-knowledge encryption by using them) - it's actually what they specialize & focus on (cloud encryption). It's 100% open source and Free to use on computers. On phones I believe it's just a 1-time fee of a few bucks ($13-14, then you have it forever) - note: their iOS offering is still new, so may be a bit unpolished at the moment.

This is the solution: https://cryptomator.org/

Cryptomator. It is made for uploading files securely to cloud storage, but works locally, is easy to use, and completely free for your use case.
