Convert a certificate
Conversion from PKCS12 to PEM
To get the private key in the file
% openssl pkcs12 -nocerts -in cert.p12 -out ~user/.globus/userkey.pem
To get the certificate in the file
% openssl pkcs12 -clcerts -nokeys -in cert.p12 -out ~user/.globus/usercert.pem
Check (and change) file modes:
% chmod 0600 userkey.pem
% chmod 0644 usercert.pem
openssl command to read the content of a certificate:
% openssl x509 -text -noout -in usercert.pem
Conversion from PEM to PKCS12
If the certificate can be found in
usercert.pem and if the private key can be found in
userkey.pem, it is possible to generate a PKCS13 file named
certif.p12 from these two files using the following command:
% openssl pkcs12 -export -out certif.p12 -inkey userkey.pem -in usercert.pem
Connect and transfer files
Only the SSH protocol is allowed for connections and file transfers to or from the CC-IN2P3 interactive servers. Two authentication modes are preferred: using password, or Kerberos ticket (via GSS-API). An RSA/DSA type authentication (SSH key) will grant you access, but will not initialize your Kerberos ticket.
