An entity that issues certificates. [re: security - olink to useful page]

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 public part of a key pair used for cryptographic operations (e.g. signing, encrypting).
