A computer system is disclosed that contains cryptographic keys and cryptographic key identifiers. The system has a repository cryptographic engine that communicates securely with a remote cryptographic engine, and the repository cryptographic engine is associated with a user data store. The user data store includes a hidden link including a session key identifier encrypted with a protection key. The hidden link is associated with a remote data entity. A key data store associated with the repository server includes a session key encrypted with a session-key-protection key. The session key is used to encrypt and decrypt the remote data entity. The system also includes a repository key exchange module operable to exchange the session key with a remote key exchange module.
