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
  

RSA-PKCS-OAEP

• Encrypt the data locally

  openssl rsautl -encrypt -inkey $ENC_KEY.pub -in data -pubin -out data.crypt -oaep
  

  or

  openssl pkeyutl -encrypt -inkey $ENC_KEY.pub -pubin -pkeyopt rsa_padding_mode:oaep -pkeyopt rsa_oaep_md:sha256 -pkeyopt rsa_mgf1_md:sha256 -in data -out data.sha256.crypt
  

• Decrypt the data on the card

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

  or

  cat data.sha256.crypt | ./pkcs11-tool --id $ENC_KEY --decrypt -p $PIN -m RSA-PKCS-OAEP --hash-algorithm=sha256  --module ../pkcs11/.libs/opensc-pkcs11.so
