I’m working on a project involving smart card communication, specifically with PIV (Personal Identity Verification) applets, and I’m having trouble understanding the use of the INS 87 (General Authentication) command as specified in ISO781… Continue reading Understanding of ISO7816-4 INS 87 GENERAL Authentication in PIV Applet [closed]
I want to deploy X.509 certificates onto a Yubikey into the certificate slots
9a: PIV Authentication
9c: Digital Signature
9d: Key Management
9e: Card Authentication
(see Yubico: PIV Introduction – Certificate Slots) according to the PIV… Continue reading Key Usage and Extended Key Usage for X.509 Certificares on Yubikey
We want to deploy a thin client architecture, where the users can sign-in into their session from every client by inserting their SmartCard into an attached reader but we have a hard time finding SmartCards that are compatible for this use… Continue reading SmartCard rollout for Windows RDP clients
I am looking to read data from European identity cards using USB smart card reader.
The purpose is to enable easier data input, e.g. when the customer is checking into a hotel.
The data that I would like to read from the ID card are alread… Continue reading How can one read data from European identity cards using smart card reader? [closed]
I just started using a Yubikey 5. I’ve set up GPG according to this excellent guide, and now I have 3 working ECC key pairs on my Yubikey: Sign/S :: ed25519, Encrypt/E :: cv25519, Authentication/A :: ed25519.
Now I want to use my Yubikey t… Continue reading Certify using Yubikey
Here is my thought process:
I want to use smartcards without passwords for my setup. We don’t want to use Iris or fingerprint or voice. I only want to put in the card whenever something needs to authenticate and when I take out the card wh… Continue reading How to mitigate spoofing, keylogging password, stealing public key with smart card with external/internal smart card reader?
I am getting the idea that Doorking’s ProxPlus cards and reader have a pre-defined encryption key in their reader. As these readers are wiegand devices and the software for the Doorking Access systems has no means of doing authentication o… Continue reading compatability of Desfire EV1/2 readers and cards with a Doorking access control system
I’ve been looking around for smart cards with support for Ed25519. More specifically, I’d like to have a TLS CA with the private key on a YubiKey. The latest YubiKey 5 supports secp256k1, secp384r1, and RSA 2048 in the PIV tool for storing… Continue reading Can I Use an OpenPGP Smart Card to Sign a TLS Certificate?
A smart card storing its secrets in it own flash storage, but does it encrypts them? Or are them in flash as plain-text? Some claim it encrypts, but if secrets are encrypted in flash, how card can use them? It need password for them from o… Continue reading Do smart cards encrypt their secrets? [closed]
How smart cards technically store their secrets?
I know smart card is whole computer on chip and it respond only to challenges. I know their software/firmware doesn’t allow (it doesn’t have the feature for that at all) to ever reveal the s… Continue reading How smart cards store their secrets? [duplicate]
