The most recent change to the pcscd package in the arch repos enables policykit This causes issues for a default install. The YubiKey is the trusted secure authentication choice for the largest technology, finance, and retail companies in the. X509Certificate2 cert = piv.GetCertificate(slot) I was banging my head on this issue all day today. Assumes there is exactly one yubikey connected and it has a RSA2048 certificate in slot 9d The YubiKey is a hardware authentication device manufactured by Yubico to protect access to computers, networks, and online services that supports one-time passwords (OTP), public-key cryptography, and authentication, and the Universal 2nd Factor (U2F) and FIDO2 protocols 1 developed by the FIDO Alliance. I would then verify the key pair using gpg. My first idea was to generate a RSA key pair, store private key on YubiKey and public key in my application. Static bool PinSubmitter(KeyEntryData pin) The YubiKey 5C Nano combines hardware-based authentication and public key cryptography to eliminate account takeovers. Essentially, I need to verify that the inserted YubiKey gives user proper authorization to use my application. But in the C# SDK there is no such argument.Ĭ# code to replicate the problem: using 509Certificates How do I decrypt in a way that gets the original message back? It's worth pointing out that in the python package "yubikey-manager" the piv.decrypt function does take a padding argument. The last line throws this error: : 'Specified key is not a valid size for this algorithm.' Can anyone explain how I can decrypt and get my original message back? Below is code that replicates the problem. The C# SDK PivSession.Decrypt method does not take a padding argument. I'm playing a little with encryption with the yubikey but getting stumped on a detail.
