serialize
serialize():
string
Serialize session to a string. This is for advanced use. May be used to keep sessions in a cache. WARNING: a user could use this cache to work around being revoked. Use with caution. WARNING: if the cache is accessible to another user, they could use it to decrypt messages they are not supposed to have access to. Make sure only the current user in question can access this cache, for example by encrypting it.
Returns
string
setManagingGroup
setManagingGroup(
groupId
,user
?):Promise
< {status
:"ok"
; } >
DEPRECATED: assign revoke rights to the group instead.
Give the rights to manage this session with the same rights as the given user to anyone belonging to given group. A common way to use this, and the default, is to set user = group
: this allows any member of the group to act as the owner of the group's MessageAccess
Warning : this can only be done by the user who created the session. If it is done by anyone else, the behavior is not guaranteed. Also, this will only have the expected behavior if the group is the only direct recipient of the session, which means that, during session creation, the group was the only recipient listed, and that encryptForSelf
was set to false
.
Parameters
Parameter | Type | Description |
---|---|---|
groupId | string | |
user ? | Recipients | Must be one of your descendants, possibly the group itself. Defaults to the group |
Returns
Promise
< { status
: "ok"
; } >
