MyProxy is an online credential repository and can function as an Online CA. You can store X.509 proxy credentials in the MyProxy repository, protected by a passphrase, for later retrieval over the network. This eliminates the need for manually copying private key and certificate files between machines. In the Online CA mode, MyProxy can issue X.509 certificates to authenticated users and supports custom authentication using PAM module. MyProxy can also be used for authentication to grid portals and credential renewal with job managers.
