GroupRoot

xmtp_mls::mls_common::group_keys

Struct GroupRoot 

pub struct GroupRoot(/* private fields */);
Expand description

The 32-byte secret that a group’s keys derive from.

Wiped on drop. Neither Copy nor Clone, so no unwiped copy outlives it, and its Debug shows nothing.

Implementations§

§

impl GroupRoot

pub fn generate() -> GroupRoot

Draw a root for one new group from the CSPRNG.

pub fn from_bytes(bytes: &[u8]) -> Result<GroupRoot, GroupRootLengthError>

Read a stored root, such as a group’s GROUP_ROOT_KEY component.

pub fn as_bytes(&self) -> &[u8; 32]

Borrow the root, to store it in the group’s AppData dictionary.
