Struct Rar5EncryptionInfo 

pub struct Rar5EncryptionInfo {
    pub version: u8,
    pub flags: u8,
    pub lg2_count: u8,
    pub salt: [u8; 16],
    pub init_v: [u8; 16],

}

RAR5 encryption information parsed from file header.

Fields

version: u8

Encryption version (must be 0)

flags: u8

Flags (0x01 = password check present, 0x02 = use MAC for checksums)

lg2_count: u8

Log2 of PBKDF2 iteration count

salt: [u8; 16]

16-byte salt

init_v: [u8; 16]

16-byte initialization vector

psw_check: Option<[u8; 8]>

Optional 8-byte password check value

psw_check_sum: Option<[u8; 4]>

Optional 4-byte password check sum

Implementations

impl Rar5EncryptionInfo

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

Parse encryption info from extra data. Format:

• vint: version
• vint: flags
• 1 byte: lg2_count
• 16 bytes: salt
• 16 bytes: init_v
• if flags & 0x01:
  • 8 bytes: psw_check
  • 4 bytes: psw_check_sum (SHA-256 of psw_check, first 4 bytes)

Trait Implementations

impl Clone for Rar5EncryptionInfo

fn clone(&self) -> Rar5EncryptionInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rar5EncryptionInfo

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

Formats the value using the given formatter.

impl PartialEq for Rar5EncryptionInfo

fn eq(&self, other: &Rar5EncryptionInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
