How to store your existing grid certificate on an Aladdin eToken

Note

On Windows

 PKCS11_MOD=$WINDIR\\system32\\etpkcs11.dll

On Linux

 PKCS11_MOD=/usr/local/lib/libetpkcs11.so

To store your existing grid certificate (usercert.pem and userkey.pem files) use the following commands

  • Convert your public certificate to DER format
 openssl x509 -in ~/.globus/usercert.pem -out usercert.der -outform der
  • Load your public certificate on the eToken (you must use your user PIN to do this):
 # pkcs11-tool --module /usr/local/lib/libetpkcs11.so \
               --label "My Grid Certificate" \
               --id 1234 \
               --login \
               -w usercert.der \
               --type cert
 Please enter User PIN:
 Generated certificate:
 Certificate Object, type = X.509 cert
   label:      Jan Just Keijser
   ID:         1234
  • Load your private key on the eToken (you must use your user PIN to do this; do this in a single step):
 # openssl rsa -in ~/.globus/userkey.pem -outform der | \
     pkcs11-tool --module /usr/local/lib/libetpkcs11.so \
                 --label "My Grid Certificate"  \
                 --id 1234 \ 
                 --login \
                 -w \
                 --type privkey
 Please enter User PIN:
 Generated private key:
 Private Key Object; RSA
 label:      Jan Just Keijser
 ID:         1234
 Usage:      decrypt, sign, unwrap

Important Notes

  • It is important that the private key is loaded onto your eToken in a single step, as your private key is decrypted first and then encrypted again using your eToken user PIN when it is stored on the eToken. Thus, if you were to store your decrypted private key in a file first (like is done for the public certificate) then your grid certificate would be seriously vulnerable to theft.
  • It is also important that the --label and --id of the certifcate and the private key match. This is used by the openssl commands and the mkproxy script to match the public certificate and private key.
