[][src]Struct sequoia_openpgp::serialize::stream::Encryptor

pub struct Encryptor<'a> { /* fields omitted */ }

Encrypts a packet stream.

Implementations

impl<'a> Encryptor<'a>[src]

pub fn for_recipients(
    inner: Message<'a, Cookie>,
    recipients: Vec<Recipient<'a>>
) -> Self
[src]

Creates a new encryptor.

The stream will be encrypted using a generated session key, which will be encrypted using the given passwords, and all encryption-capable subkeys of the given Certs.

Unless otherwise specified, the stream is encrypted using AES256. If aead_algo is None, a SEIP packet is emitted, otherwise the given AEAD algorithm is used.

Key preferences of the recipients are not honored.

Example

use std::io::Write;
extern crate sequoia_openpgp as openpgp;
use openpgp::cert::prelude::*;
use openpgp::types::KeyFlags;
use openpgp::serialize::stream::{
    Message, Encryptor, LiteralWriter,
};
use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

let cert = Cert::from_bytes(
    "-----BEGIN PGP PUBLIC KEY BLOCK-----

     mQENBFpxtsABCADZcBa1Q3ZLZnju18o0+t8LoQuIIeyeUQ0H45y6xUqyrD5HSkVM
     ...
     -----END PGP PUBLIC KEY BLOCK-----"
).unwrap();

// Build a vector of recipients to hand to Encryptor.
let recipients =
    cert.keys().with_policy(p, None).alive().revoked(false)
    // Or `for_storage_encryption()`, for data at rest.
    .for_transport_encryption()
    .map(|ka| ka.key().into())
    .collect();

let mut o = vec![];
let message = Message::new(&mut o);
let encryptor =
    Encryptor::for_recipients(message, recipients)
        .build().expect("Failed to create encryptor");
let mut w = LiteralWriter::new(encryptor).build()?;
w.write_all(b"Hello world.")?;
w.finalize()?;

pub fn with_passwords(
    inner: Message<'a, Cookie>,
    passwords: Vec<Password>
) -> Self
[src]

Creates a new encryptor.

The stream will be encrypted using a generated session key, which will be encrypted using the given passwords, and all encryption-capable subkeys of the given Certs.

Unless otherwise specified, the stream is encrypted using AES256. If aead_algo is None, a SEIP packet is emitted, otherwise the given AEAD algorithm is used.

Key preferences of the recipients are not honored.

Example

use std::io::Write;
extern crate sequoia_openpgp as openpgp;
use openpgp::types::KeyFlags;
use openpgp::serialize::stream::{
    Message, Encryptor, LiteralWriter,
};
let mut o = vec![];
let message = Message::new(&mut o);
let encryptor =
    Encryptor::with_passwords(message,
                              vec!["совершенно секретно".into()])
        .build().expect("Failed to create encryptor");
let mut w = LiteralWriter::new(encryptor).build()?;
w.write_all(b"Hello world.")?;
w.finalize()?;

pub fn add_recipient(self, recipient: Recipient<'a>) -> Self[src]

Adds a recipient.

pub fn add_password(self, password: Password) -> Self[src]

Adds a password.

pub fn sym_algo(self, algo: SymmetricAlgorithm) -> Self[src]

Sets the symmetric algorithm to use.

pub fn aead_algo(self, algo: AEADAlgorithm) -> Self[src]

Enables AEAD and sets the AEAD algorithm to use.

This feature is experimental.

pub fn build(self) -> Result<Message<'a, Cookie>>[src]

Finalizes the encryptor, returning the writer stack.
