Trait Implementations

impl Crypt for Hxv4Crypt

fn startup_tjs_not_encrypted(&self) -> bool

whether the startup.tjs script is not encrypted even when the archive is encrypted.

fn obfuscated_index(&self) -> bool

whether XP3 index is obfuscated:

fn hash_after_crypt(&self) -> bool

whether Adler32 checksum should be calculated after contents have been encrypted.

fn init(&self, archive: &mut Xp3Archive<'_>) -> Result<()>

Initializes the cryptographic context for the archive.

fn decrypt_supported(&self) -> bool

Returns true if this crypt support decrypt

fn decrypt_seek_supported(&self) -> bool

Returns true if this crypt support seek when decrypting

fn decrypt<'a>( &self, entry: &Xp3Entry, cur_seg: &Segment, stream: Box<dyn Read + Send + Sync + 'a>, ) -> Result<Box<dyn ReadDebug + Send + Sync + 'a>>

Decrypts the given stream of data for the specified entry and segment.

fn decrypt_with_seek<'a>( &self, entry: &Xp3Entry, cur_seg: &Segment, stream: Box<dyn ReadSeek + Send + Sync + 'a>, ) -> Result<Box<dyn ReadSeek + Send + Sync + 'a>>

Decrypts the given stream of data for the specified entry and segment, with seek support.

fn read_name<'a>( &self, reader: &mut Box<dyn Read + 'a>, ) -> Result<(String, u64)>

Read a entry name from archive index

fn need_filter(&self, _filename: &str, _buf: &[u8], _buf_len: usize) -> bool

Determine whether the file with the given name and content need to be extra processed after decryption. (e.g. extra decryption by file type)

fn filter_seek_supported(&self) -> bool

Returns true if this crypt support seek when filtering

fn filter<'a>( &self, _entry: Entry<'a>, ) -> Result<Box<dyn ReadDebug + Send + Sync + 'a>>

Apply extra processing to the decrypted content of the file.

fn filter_with_seek<'a>( &self, _entry: Entry<'a>, ) -> Result<Box<dyn ReadSeek + Send + Sync + 'a>>

Apply extra processing to the decrypted content of the file, with seek support.

impl Debug for Hxv4Crypt

where Mutex<Option<HxCrypt>>: Debug, Arc<HashMap<FileHash, String>>: Debug, Arc<HashMap<PathHash, String>>: Debug, Vec<KeyPackage>: Debug, String: Debug,

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

Formats the value using the given formatter.
