Struct Keychain 

pub struct Keychain {
    pub version: u32,
    pub header_size: u32,
    pub auth_offset: u32,
    pub tables: Vec<Table>,
    pub commit_version: Option<u32>,
}

A parsed keychain database.

Fields

version: u32

header_size: u32

Header size field (16 in every observed file).

auth_offset: u32

Purpose unknown; 0 in every observed file.

tables: Vec<Table>

Tables in file order. Order is preserved because the file’s table offset array is written in this order.

commit_version: Option<u32>

A u32 that follows the tables array, outside its declared size. macOS writes 1 for a fresh keychain and increments it once per committed write, so it reads as a commit counter. Preserved, and bumped by Self::bump_commit_version when this code modifies the database. None for a file that has no such trailer.

Implementations

impl Keychain

pub fn parse(data: &[u8]) -> Result<Self>

Parse a keychain image. The schema is read from the file itself.

pub fn schema(&self) -> Result<Schema>

The schema this file declares.

pub fn bump_commit_version(&mut self)

Record another committed write, the way macOS does.

pub fn table(&self, record_type: RecordType) -> Option<&Table>

pub fn table_mut(&mut self, record_type: RecordType) -> Option<&mut Table>

pub fn to_bytes(&self) -> Result<Vec<u8>>

Serialize back to a file image.

Trait Implementations

impl Clone for Keychain

fn clone(&self) -> Keychain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Keychain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
