Struct dmgwiz::EncryptedDmgReader

pub struct EncryptedDmgReader<R> {
    pub verbosity: Verbosity,
    // some fields omitted
}

Reader to read from encrypted DMGs

Use this to transparently read from encrypted DMGs. Support AES-128 and AES-256 encryption.

See main.rs for a real-world example.

Fields

verbosity: Verbosity

Implementations

impl<R> EncryptedDmgReader<R> where
    R: Read + Seek, 

pub fn from_reader(
    reader: R,
    password: &str,
    verbosity: Verbosity
) -> Result<EncryptedDmgReader<R>>

Create a EncryptedDmgReader instance from a seekable byte stream

Arguments

• input - A seekable reader
• password - Password for decryption
• verbosity - Verbosity for debugging

Example

use std::fs::File;
use dmgwiz::{EncryptedDmgReader, Verbosity};

let input = File::open("tests/input_aes256.dmg").unwrap();
let mut reader = match EncryptedDmgReader::from_reader(input, "test123", Verbosity::None) {
    Err(err) => panic!(format!("could not read input file - {}", err)),
    Ok(val) => val,
};

pub fn read_all<W>(&mut self, output: W) -> Result<usize> where
    W: Write, 

Decrypt all data and write to output

Arguments

• output - A seekable writer

Example

use std::fs::File;
use dmgwiz::{EncryptedDmgReader, Verbosity};

let input = File::open("tests/input_aes256.dmg").unwrap();
let output = File::create("tests/output.dmg").unwrap();
let mut reader = EncryptedDmgReader::from_reader(input, "test123", Verbosity::None).unwrap();
match reader.read_all(output) {
    Err(err) => panic!(format!("error while decrypting: {}", err)),
    Ok(bytes) => println!("done. {} bytes written", bytes),
}

Trait Implementations

impl<R: Read + Seek> Read for EncryptedDmgReader<R>

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl<R> Seek for EncryptedDmgReader<R>

fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Seek to an offset, in bytes, in a stream.

fn stream_len(&mut self) -> Result<u64, Error>

🔬 This is a nightly-only experimental API. (seek_convenience)

Returns the length of this stream (in bytes).

fn stream_position(&mut self) -> Result<u64, Error>

🔬 This is a nightly-only experimental API. (seek_convenience)

Returns the current seek position from the start of the stream.
