"""Attestations ensure that users and groups can't lie about their memberships. |
||||
|
||||
When a user joins a group the HS and GS swap attestations, which allow them |
||||
both to independently prove to third parties their membership.These |
||||
attestations have a validity period so need to be periodically renewed. |
||||
|
||||
If a user leaves (or gets kicked out of) a group, either side can still use |
||||
their attestation to "prove" their membership, until the attestation expires. |
||||
Therefore attestations shouldn't be relied on to prove membership in important |
||||
cases, but can for less important situations, e.g. showing a users membership |
||||
of groups on their profile, showing flairs, etc. |
||||
|
||||
An attestation is a signed blob of json that looks like: |
||||
|
||||
{ |
||||
"user_id": "@foo:a.example.com", |
||||
"group_id": "+bar:b.example.com", |
||||
"valid_until_ms": 1507994728530, |
