 | Calculating RSA/ECDSA signature | Calculating the RSA or ECDSA signature value in browser or desktop/server environment. The operation involves connecting with the signature token’s driver, sending the data to be signed and receiving digital signature value calculated with the token owner’s RSA or ECDSA private key. The following cryptographic tokens are supported: hardware-based tokens (e.g. PKCS#11-based eID cards, USB cryptostick, Mobile-ID and Smart-ID); software-based tokens (e.g. PKCS#12 software token). |
 | Card management operations | PIN/PUK management, reading personal data file. |
 | Authentication | Authentication with ID-card. The operation is generally done via native operating system/browser components. In case of Estonian ID-cards and Firefox browser, a PKCS#11 module pkcs11-register is used for setting the proper parameters for authentication in Firefox browser on Linux. |
