Struct sequoia_openpgp::message::Message[][src]

pub struct Message { /* fields omitted */ }
Expand description

A message.

An OpenPGP message is a structured sequence of OpenPGP packets. Basically, it’s an optionally encrypted, optionally signed literal data packet. The exact structure is defined in Section 11.3 of RFC 4880.

ASCII Armored Messages are wrapped in -----BEGIN PGP MESSAGE----- header and -----END PGP MESSAGE----- tail lines:

-----BEGIN PGP MESSAGE-----

Examples

Creating a Message encrypted with a password.

use std::io::Write;
use openpgp::serialize::stream::{Message, Encryptor, LiteralWriter};

let mut sink = vec![];
let message = Encryptor::with_passwords(
    Message::new(&mut sink), Some("ściśle tajne")).build()?;
let mut w = LiteralWriter::new(message).build()?;
w.write_all(b"Hello world.")?;
w.finalize()?;

Implementations

Returns the body of the message.

Returns None if no literal data packet is found. This happens if a SEIP container has not been decrypted.

Examples

use std::io;
use std::io::Read;
use openpgp::Message;
use openpgp::armor::{Reader, ReaderMode};
use openpgp::parse::Parse;

let data = "yxJiAAAAAABIZWxsbyB3b3JsZCE="; // base64 over literal data packet

let mut cursor = io::Cursor::new(&data);
let mut reader = Reader::new(&mut cursor, ReaderMode::VeryTolerant);

let mut buf = Vec::new();
reader.read_to_end(&mut buf)?;

let message = Message::from_bytes(&buf)?;
assert_eq!(message.body().unwrap().body(), b"Hello world!");

Methods from Deref<Target = PacketPile>

Pretty prints the message to stderr.

This function is primarily intended for debugging purposes.

Returns a reference to the packet at the location described by pathspec.

pathspec is a slice of the form [0, 1, 2]. Each element is the index of packet in a container. Thus, the previous path specification means: return the third child of the second child of the first top-level packet. In other words, the starred packet in the following tree:

        PacketPile
       /     |     \
      0      1      2  ...
    /   \
   /     \
 0         1  ...
       /   |   \  ...
      0    1    2
                *

And, [10] means return the 11th top-level packet.

Note: there is no packet at the root. Thus, the path [] returns None.

Examples

let pile = PacketPile::from(packets);

if let Some(packet) = pile.path_ref(&[0]) {
    // There is a packet at this path.
}

if let None = pile.path_ref(&[0, 1, 2]) {
    // But none here.
}

Returns an iterator over all of the packet’s descendants, in depth-first order.

let mut lit = Literal::new(DataFormat::Text);
lit.set_body(b"test".to_vec());

let pile = PacketPile::from(vec![lit.into()]);

for packet in pile.descendants() {
    assert_eq!(packet.tag(), Tag::Literal);
}

Returns an iterator over the top-level packets.

let mut lit = Literal::new(DataFormat::Text);
lit.set_body(b"test".to_vec());

let pile = PacketPile::from(vec![lit.into()]);

assert_eq!(pile.children().len(), 1);

Converts the PacketPile to a Message.

Converting a PacketPile to a Message doesn’t change the packets; it asserts that the packet sequence is an optionally encrypted, optionally signed, optionally compressed literal data packet. The exact grammar is defined in Section 11.3 of RFC 4880.

Caveats: this function assumes that any still encrypted parts or still compressed parts are valid messages.
