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
-
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
-
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.
-
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
.
-
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
-
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
-
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
-
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
-
Encrypt the data locally
openssl rsautl -encrypt -inkey $ENC_KEY.pub -in data -pubin -out data.crypt -oaep
or

-
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

Hello,
We used a different command and it worked.
Thank you for your support.
