• Add android.yubikey.intent.action.CHALLENGE_RESPONSE intent
• Add KeePassDX in README

[pp3345]

I am sorry for the late reply. I am fine with adding KeePassDX to the README, however, I am concerned about the proposed new name for the intent for two reasons:

• I believe that the "android" namespace is reserved for Android itself and user applications shouldn't add their own intents there. Please correct me if I am wrong.
• "YubiKey" is a copyrighted trademark. ykDroid was initially called "YubiDroid", but then Yubico came and threatened to sue me over the name, hence I renamed it to ykDroid. I am not sure whether they would be fine with this. I might be overreacting here.

I believe that the "android" namespace is reserved for Android itself and user applications shouldn't add their own intents there. Please correct me if I am wrong.

What do you mean by reserving it for Android itself?
It's not annoying in my opinion especially for an Intent that is meant to be shared and harmonized to make it a standard. It would be more annoying if third party applications use Android namespace as package name, even if some of them do it and are approved by the PlayStore (com.android.KeePass -> KeePassDroid). But we can remove the word android if it bothers you.

"YubiKey" is a copyrighted trademark. ykDroid was initially called "YubiDroid", but then Yubico came and threatened to sue me over the name, hence I renamed it to ykDroid. I am not sure whether they would be fine with this. I might be overreacting here.

Agree with this, even if it goes against their marketing plan to spread the name. In this case we can use the "ykdroid" name generically, that would fit the protocol you initially set up. without your package name.

I am making another driver application that will be compatible with Yubikey and SoloKey (Fido2) on the same principle as your protocol. If you don't mind, I'll reuse the name "ykDroid" to indicate that the intent format is compatible with yours. If it bothers you, I can use "ykey" name.

What do you think of :
ykdroid.intent.action.CHALLENGE_RESPONSE

or

ykey.intent.action.CHALLENGE_RESPONSE
