In the context of Condensation, a hash is a 32-byte (256-bit) value denoting the SHA-256 hash of some byte sequence.
In binary context, e.g. in the hash list of an object, hashes are written as 32 bytes. In textual context, hashes are written as 64 consecutive hex digits, in the order of the bytes:
Hashes are used in different contexts, and for different purposes.
An object's hash is also used to verify its integrity.
On a HTTP store, an object may be referred to as follows:
The hash of an object uniquely identifies the tree it spans. Hence, a tree hash is simply the hash of its root object.
An actor hash also identifies its actor group.
When an actor accesses a store, it uses its actor hash as account hash. This allows the store to authenticate the actor by retrieving its public key, and verifying its signature.
On a HTTP store, an account may be referred to as follows:
and its boxes are:
