An identifier for the certificate owner, e.g. "/DC=org/DC=doegrids/OU=People/CN=John Doe 123456". The subject is part of the information the CA binds to a public key when creating a certificate.

The private part of a key pair. Depending on the type of certificate the key corresponds to it may typically be found in $HOME/.globus/userkey.pem (for user certificates), /etc/grid-security/hostkey.pem (for host certificates) or /etc/grid-security/<service>/<service>key.pem (for service certificates).

For more information on possible private key locations see [Credentials in the Pre-WS Authentication & Authorization Developer's Guide ("Environmental Variables" section)].

A short lived certificate issued using a EEC. A proxy certificate typically has the same effective subject as the EEC that issued it and can thus be used in its place. GSI uses proxy certificates for single sign on and delegation of rights to other entities.

For more information about types of proxy certificates and their compatibility in different versions of GT, see http://dev.globus.org/wiki/Security/ProxyCertTypes.

The combination of a proxy certificate and its corresponding private key. GSI typically stores proxy credentials in /tmp/x509up_u<uid> , where <uid> is the user id of the proxy owner.

The combination of a user certificate and its corresponding private key.
