Function check_group_root 

pub fn check_group_root(
    extensions: &Extensions<GroupContext>,
    group_id: &[u8],
) -> Result<GroupKeys, GroupRootError>
Expand description

Require the root in a group context to derive group_id, and return the keys it derives. A 16-byte group id never matches: every derived id is a 32-byte public key.
