38 get_self_credential a degenerate version of get_credential used by a client
39 to get his initial credential when de doesnt have one. This is the same as
40 get_credetial(..., cred = None, ...)
42 The registry ensures that the client is the principal that is named by
43 (type, name) by comparing the public key in the record's GID to the
44 private key used to encrypt the client side of the HTTPS connection. Thus
45 it is impossible for one principal to retrive another principal's
46 credential without having the appropriate private key.
