Detailed Description

This class is used to express an access policy.

The current version of this class is a trivial acceptance of any Credentials. It is designed to provide an interface for a mechanism such as SDSI or KeyNote.

Deprecated:

Access rights are granted by a private key operation, and this class holds the corresponding public key used to verify that the rights have been granted. The public key is signed by another authority, such as the owner of the access-controlled data.

Member Function Documentation

int Policy::marshal (  unsigned char **    pp )  const [virtual]

This function creates a serialized representation of the object, which is returned through the argument pp. This must be overridden by the concrete derived class. Parameters: pp  Serialized form of the object Returns: Length of the marshalled data Implements CODEX_ASN1::Base. Definition at line 60 of file Policy.cc. Referenced by CODEX_Client::Interface::codex_create_policy(), and CODEX_Client::CreateKeyMsg::marshal().

void * Policy::unmarshal (  void *    bogus, unsigned char **    pp, long    length )  [virtual]

This function takes a serialized representation of the object and recreates the object representation. This must be overridden by the concrete derived class. Parameters: bogus  Included for compatibility with OpenSSL ASN.1 macros pp  Serialized form of the data length  Number of bytes of pp to unmarshal Returns: success or failure of the unmarshalling Implements CODEX_ASN1::Base. Definition at line 66 of file Policy.cc. References CODEX_ASN1::Base::m_initialized. Referenced by CODEX_Client::Interface::codex_create_key(), CODEX_Client::Client::createPolicy(), and CODEX_Client::CreateKeyMsg::unmarshal().

bool Policy::verify (  const Credentials &    credentials )  const

Verify that a Credentials object satisfies the policy. Parameters: credentials  The credentials presented. Return values: true  if the Credentials satisfy this Policy false  if the Credentials do not satisfy this Policy Definition at line 54 of file Policy.cc. Referenced by CODEX_KeyService::ClientMessageVerifier::handler().
