Sign/Verify using private key/certificate

  • Create a data to sign

    echo "data to sign (max 100 bytes)" > data
    
  • Get the certificate from the card:

    ./pkcs11-tool -r -p $PIN --id $SIGN_KEY --type cert --module ../pkcs11/.libs/opensc-pkcs11.so > $SIGN_KEY.cert
    
  • Convert it to the public key (PEM format)

    openssl x509 -inform DER -in $SIGN_KEY.cert -pubkey > $SIGN_KEY.pub
    

or

  • Get the public key from the card:

     ./pkcs11-tool -r -p $PIN --id $SIGN_KEY --type pubkey --module ../pkcs11/.libs/opensc-pkcs11.so > $SIGN_KEY.der
    
  • Convert it to PEM format:

    openssl rsa -inform DER -outform PEM -in $SIGN_KEY.der -pubin > $SIGN_KEY.pub
    

RSA-PKCS

  • Sign the data on the smartcard using private key:

    cat data | ./pkcs11-tool --id $SIGN_KEY -s -p $PIN -m RSA-PKCS --module ../pkcs11/.libs/opensc-pkcs11.so > data.sig
    
  • Verify

    openssl rsautl -verify -inkey $SIGN_KEY.pub -in data.sig -pubin
    

SHA1-RSA-PKCS

  • Sign the data on the smartcard using private key:

    cat data | ./pkcs11-tool --id $SIGN_KEY -s -p $PIN -m SHA1-RSA-PKCS --module ../pkcs11/.libs/opensc-pkcs11.so > data.sig
    
  • Verify and parse the returned ASN1 structure:

    openssl rsautl -verify -inkey $SIGN_KEY.pub -in data.sig -pubin | openssl asn1parse -inform DER
    
  • Compare the result with the sha1 sum of the input file:

    sha1sum data
    

Similarily can be tested the SHA256, SHA384 and SHA512, just by replacing SHA1 with these hashes in above commands.

SHA1-RSA-PKCS-PSS

  • Sign the data on the smartcard using private key:

     cat data | ./pkcs11-tool --id $SIGN_KEY -s -p $PIN -m SHA1-RSA-PKCS-PSS --module ../pkcs11/.libs/opensc-pkcs11.so > data.sig
    
  • Verify

    openssl dgst -keyform DER -verify $SIGN_KEY.pub -sha1 -sigopt rsa_padding_mode:pss -sigopt rsa_pss_saltlen:-1 -signature data.sig data
    

For other parameters, replace the hash algorithsm, add a --salt-len parameter for the pkcs11-tool and adjust rsa_pss_saltlen argument of openssl.

RSA-X-509

  • Prepare data with padding:

    (echo -ne "\x00\x01" && for i in `seq 224`; do echo -ne "\xff"; done && echo -ne "\00" && cat data) > data_pad
    
  • Sign the data on the smartcard using private key:

    cat data_pad | ./pkcs11-tool --id $SIGN_KEY -s -p $PIN -m RSA-X-509 --module ../pkcs11/.libs/opensc-pkcs11.so > data_pad.sig
    
  • Verify

    openssl rsautl -verify -inkey $SIGN_KEY.pub -in data_pad.sig -pubin -raw
    

Encrypt/Decrypt using private key/certificate

  • Create a data to encrypt

    echo "data to encrpyt should be longer, better, faster and whatever we need to hide in front of nasty eyes of the ones that should not see them. " > data
    
  • Get the certificate from the card:

    ./pkcs11-tool -r -p $PIN --id $ENC_KEY --type cert --module ../pkcs11/.libs/opensc-pkcs11.so > $ENC_KEY.cert
    
  • Convert it to the public key (PEM format)

    openssl x509 -inform DER -in $ENC_KEY.cert -pubkey > $ENC_KEY.pub
    

RSA-PKCS

  • Encrypt the data locally

    openssl rsautl -encrypt -inkey $ENC_KEY.pub -in data -pubin -out data.crypt
    
  • Decrypt the data on the card

    cat data.crypt | ./pkcs11-tool --id $ENC_KEY --decrypt -p $PIN -m RSA-PKCS --module ../pkcs11/.libs/opensc-pkcs11.so
    

RSA-X-509

  • Prepare data with padding:

    (echo -ne "\x00\x02" && for i in `seq 113`; do echo -ne "\xff"; done && echo -ne "\00" && cat data) > data_pad
    
  • Encrypt the data locally

    openssl rsautl -encrypt -inkey $ENC_KEY.pub -in data_pad -pubin -out data_pad.crypt -raw
    
  • Decrypt the data on the card

    cat data_pad.crypt | ./pkcs11-tool --id $ENC_KEY --decrypt -p $PIN -m RSA-X-509 --module ../pkcs11/.libs/opensc-pkcs11.so
