Hello, That's my first time that I really need to understand how the smart card works. First of all I have with me a Brazilian Digital Document called e-CPF, this card is an Version V2 with 2048 bits and is part of IPC-BRAZIL. Every thing start because I need to sign my device serial number with my smart card, in the documentation that I need to follow just say that I need sign a number like "290953052" and after sign I need to get an data string in base64, followed the PKCS #1 version 1.5. My First question, there is an chance to outsource the private key inside the smart card?
No. That is the point of a smart card, the private key can not be read. It can only be used for decryption or signing. (The public key in a certificate is used for encryption or verifying signatures.) (The issuer of the card may be able to read it, but not ordinary users.)
I asked that because if I get the private key I can do that using openssl.
You might be able to use OpenSSL, if the card has an openssl engine or the card has a PKCS#11 library. (OpenSC has an openssl_engine for use with PKCS#11.) OpenSC also has PKCS#11 for some cards. Not clear if the e-cnpj is supported or not. People have asked in the past. https://github.com/OpenSC/OpenSC/wiki https://github.com/OpenSC/OpenSC/wiki/Supported-hardware-%28smart-cards-and-USB-tokens%29 Google for: opensc smart card e-cnpj
But if this happen I cant see an reason for smart cards work well. Im sorry to ask this basics questions but I realy got difficult to find informations.
