Christian Heimes 5197422ef6 Vault: Explicitly default to 3DES CBC 
The server-side plugin for IPA Vault relied on the fact that the default
oid for encryption algorithm is 3DES in CBC mode (DES-EDE3-CBC). Dogtag
10.4 has changed the default from 3DES to AES. Pass the correct
algorithm OID to KeyClient.archive_encrypted_data().

Based on the ownership there are three vault categories:

User vaults are vaults owned used by a particular user. Private
vaults are vaults owned the current user. Service vaults are
vaults owned by a service. Shared vaults are owned by the admin
