+%description
+This package is a server for binding data to network presence.
+First, the client gets a list of the Tang server's advertised asymmetric keys.
+This can happen online by a simple HTTP GET. Alternatively, since the keys are
+asymmetric, the public key list can be distributed out of band.
+Second, the client uses one of these public keys to generate a unique,
+cryptographically strong encryption key. The data is then encrypted using this
+key. Once the data is encrypted, the key is discarded. Some small metadata is
+produced as part of this operation which the client should store in a convenient
+location. This process of encrypting data is the provisioning step.
+Third, when the client is ready to access its data, it simply loads the metadata
+produced in the provisioning step and performs an HTTP POST in order to recover
+the encryption key. This process is the recovery step.
