copy private key from smart card You can't extract the private key out of a PIV smartcard, as this is done as a . Alright, we purchase a microcontroller and a NFC reader module along with some compatible NFC cards. For the purpose of this post, I went with an Arduino Uno and a PN532 breakout module. The module offers a fully programmable NFC interface and is connected to the Arduino via the SPI port. . 1 Reply to “NFC Hacking: Part 1 – Authentication .

This is a video that will help you connect your NFC device with the Moto Z Play.
It is possible to export the certificate and copy to your laptop but to identify, sign or decrypt it is necessary to use the private key. The private key is usually generated on the smartcard and is not extractable.Using PuTTy integration, it works great for SSH authentication. I was under the impression that .

It is possible to export the certificate and copy to your laptop but to identify, sign or decrypt it is necessary to use the private key. The private key is usually generated on the smartcard and is not extractable.
Using PuTTy integration, it works great for SSH authentication. I was under the impression that you shouldn't be able to export the private key if it is safely stored on the smart card (YubiKey), as crypto operations are handed off to the cards onboard processor to avoid it leaving.

You can't extract the private key out of a PIV smartcard, as this is done as a secure vault for the private key. But you can use a Putty agent compatible with Pageant which uses a PIV card as a secure key storage, that's the clear goal of PIVageant, that my company developed. Secret keys cannot be exported from OpenPGP smart cards -- that's the very idea behind them. If you created the key on a computer and imported it to the smart card, use the backup to copy it to the Yubikey. Otherwise, you'll have to create a new key.

This is what the United States Department of Defense (DoD) uses all around. You could look around on the web to see where you can get a free copy. Importing a GPG (openPGP) Certificate. Transferring, or importing, the private onto the Smartcard is a bit easier than importing PIV certificates. You can use the usual gpg tools. gpg --card-statusConsider you lost your laptop with sensitive data and your smart card that contains the private key for your GnuPG and Truecrypt accounts. The smartcard is secured with a 8-digit PIN.
Exporting a certificate with Private Key. On the workstation where you enrolled the smart card certificates, choose Start, choose Run, and then in the Open box, type MMC. Choose OK. On the Console page, on the File menu, select Add/Remove Snap in.Use the IX509Enrollment->CreateRequest method with XCN_CRYPT_STRING_BINARY to obtain the serialized request. Depending on how you initialized your instance of IX509Enrollement, you can get a PKCS#10 request or a CMC . I have generated a pair of RSA keys on a smart card with OpenSC tools and retrieved it as wrapped key blob encrypted with DKEK key:
Software can ask the smart card to perform cryptographic operations on its behalf without disclosing the key to the computer (in fact, there is no reasonable way to extract the private key from a smart card). To prevent unauthorized use the smart code requires the user provide a short PIN.
