Struct safe_core::MDataInfo

pub struct MDataInfo {
    pub name: XorName,
    pub type_tag: u64,
    pub enc_info: Option<(Key, Option<Nonce>)>,
    pub new_enc_info: Option<(Key, Option<Nonce>)>,
}

Information allowing to locate and access mutable data on the network.

Fields

name: XorName

Name of the data where the directory is stored.

type_tag: u64

Type tag of the data where the directory is stored.

enc_info: Option<(Key, Option<Nonce>)>

Key to encrypt/decrypt the directory content. and the nonce to be used for keys

new_enc_info: Option<(Key, Option<Nonce>)>

Future encryption info, used for two-phase data reencryption.

Methods

impl MDataInfo

fn new_private(
    name: XorName,
    type_tag: u64,
    enc_info: (Key, Option<Nonce>)
) -> Self

Construct MDataInfo for private (encrypted) data with a provided private key.

fn new_public(name: XorName, type_tag: u64) -> Self

Construct MDataInfo for public data.

fn random_private(type_tag: u64) -> Result<Self, CoreError>

Generate random MDataInfo for private (encrypted) mutable data.

fn random_public(type_tag: u64) -> Result<Self, CoreError>

Generate random MDataInfo for public mutable data.

fn enc_key(&self) -> Option<&Key>

Returns the encryption key, if any.

fn nonce(&self) -> Option<&Nonce>

Returns the nonce, inf any.

fn enc_entry_key(&self, plain_text: &[u8]) -> Result<Vec<u8>, CoreError>

encrypt the the key for the mdata entry accordingly

fn enc_entry_value(&self, plain_text: &[u8]) -> Result<Vec<u8>, CoreError>

encrypt the value for this mdata entry accordingly

fn decrypt(&self, cipher: &[u8]) -> Result<Vec<u8>, CoreError>

decrypt key or value of this mdata entry

fn start_new_enc_info(&mut self)

Start the encryption info re-generation by populating the new_enc_info field with random keys.

fn commit_new_enc_info(&mut self)

Commit the encryption info re-generation by replacing the current encryption info with new_enc_info (if any).

fn abort_new_enc_info(&mut self)

Abort the encryption info regeneration by clearing the new_enc_info field.

Trait Implementations

impl Clone for MDataInfo

fn clone(&self) -> MDataInfo
