The certificate must have a valid user principal name (UPN). The certificate must have the digital signature key usage. The certificate must have the smart card logon EKU. Any certificate that meets these requirements is displayed to the user with the certificate's UPN (or e-mail address or subject. Using SSH Public Key Authentication with a Smart Card. So without more delay, here is the actual command I used to generate my certificate: $ openssl req -engine pkcs11 -new -key 'pkcs11:object=RSA2k48' -keyform engine -out myCert.pem -days 3650 -outform pem -x509 -utf8 engine 'pkcs11' set. Enter PKCS#11 token PIN for UserPIN (GIDS card.
Nov 16, 2018 Doing so will just create certificate objects and the private key metadata, but no key. Please use the Smart Card Shell to import keys and certificates from PKCS #12 files. Further test scripts can be found in the Smart Card Shell Script Collection. Reader support. Jun 21, 2018 This section shows how you can set up a Smart Card certificate template on the server that can be used to self-enroll a smart card. In the Server Manager, choose Tools, then Certification Authority. Expand your server name to reveal Certificate Folders. Right click the Certificate Templates folder and choose Manage.
Because the security of public-key cryptography (including certificate and public-key authentication) relies heavily on the confidentiality of the private key, it is important to keep the private key secure. If the private key is stored for example on the local hard drive, it is very important that only the intended user has read access to the private key. If someone could obtain the private key, they could potentially mount a brute-force or a dictionary attack to discover the passphrase of the private key, and security would be void.
If the security of the machine on which public-key or certificate authentication is used cannot be guaranteed, or if a higher level of security is desired, the private key (and any public keys or certificates) can be stored on a smart card or another two-factor authentication token.
Storing the private key and public key or certificate on a smart card can also be convenient if a user uses many different machines to connect from. Storing a copy of the key pair on each machine is often not desirable and transporting the key pair on a floppy disk or other easily damaged or copied media may not be convenient or secure. A smart card could be used in this type of scenario to store the private key and certificate or the public key, and none of the secret key material would need to be stored on the client computers.

In SSH Tectia Client and Connector 5.x, the Connection Broker component can be used as a key provider for accessing keys and certificates from disk files and hardware cryptographic devices. It can also be used as an authentication agent to store passphrases for key pairs.

Change key size
The card is programmed for a specific key size for each slot. This can be changed easily:
If you want to use GnuPG and generate all keys on card without backup, just continue the process without interrupting.
Note: The 'Make off-card backup of encryption key' option creates a backup file for the first key only, not the other two keys.
Backup needed?
You have two options:

Move GPG key to card
The
keytocard command will move a secret key to the smart card.
Note: It is a good idea to create a backup before proceeding and keep it in a safe place, e.g. https://generousconcepts723.weebly.com/generate-warcraft-3-frozen-throne-cd-keys.html. offline and encrypted.
In order to copy the private key onto the card instead of moving it, have a look at
addcardkey .
Note: The public GPG key including all meta data - e.g. name, email address, photo, .. - still resides in your keychain. In order to be able to restore your keychain or use the key on another computer, it is a good idea to export and upload the public key, then store the URL on the card:

First, let's generate a new RSA public/private key pair:
Note: It is perfectly fine to skip the previous step and use an existing private key from an X509 certificate or an SSH private key file, depending on your use case.
Now, copy the private key to a card:

It is possible to let the smart card generate a public/private key pair on a specific slot (01.03). This is most useful for generating the authentication key (id 03) on card, while the other keys (01 and 02) may have been generated off-card in order to create a backup.
Ssh generate public key mac. Note: The generated key pair can not (easily) be used for GnuPG, because a suitable import mechanism for the GnuPG keychain is not available at the moment. (Although, this would be a nice feature for the micro-ca-tool.)
