I have one Yubikey which works fine with KeeChallenge. If I program another Yubikey using the same Secret Key, will it open my original KeePass database without having to use recovery mode or update anyting in Keepass? In other words, can just duplicate hardware (Yubikey) without any software changes? On a related note... If I forget my Secret Key, but have working Yubikey programmed with that Secret Key, I will be able to open a copy of the original database on a new PC. Correct?

I am having the same issue: there is no Recovery Mode option or button when using with portable KeePass-2.43 for Windows. Otherwise, works well, thank you for good product!

I'm not a cryptography-expert. However, I'd like to understand why the KeeChallenge approach is safe. HMAC is usually used to verify authentication and data integrity of a message where sender and receiver are required to hold a shared secret. If I understand it correctly, KeyChallenge uses the HMAC as the AES key to en/decrypt the shared secret (stored in XML file). The challenge is used as some kind of salt mechanism. Thus: R = AESenc(S, HMAC(S, C)) S = AESdec(R, HMAC(S, C)) where: - S is the shared...
