Struct sequoia_openpgp::parse::stream::DecryptorBuilder

pub struct DecryptorBuilder<'a> { /* private fields */ }

A builder for Decryptor.

This allows the customization of Decryptor, which can be built using DecryptorBuilder::with_policy.

Implementations

impl<'a> DecryptorBuilder<'a>

pub fn buffer_size(self, size: usize) -> Self

Changes the amount of buffered data.

By default, we buffer up to 25 megabytes of net message data (see DEFAULT_BUFFER_SIZE). This changes the default.

Examples

use sequoia_openpgp as openpgp;
use openpgp::parse::{Parse, stream::*};
use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

struct Helper {};
impl VerificationHelper for Helper {
    // ...
}
impl DecryptionHelper for Helper {
    // ...
}

let message =
    // ...

let h = Helper {};
let mut v = DecryptorBuilder::from_bytes(message)?
    .buffer_size(1 << 12)
    .with_policy(p, None, h)?;

pub fn mapping(self, enabled: bool) -> Self

Enables mapping.

If mapping is enabled, the packet parser will create a Map of the packets that can be inspected in VerificationHelper::inspect. Note that this buffers the packets contents, and is not recommended unless you know that the packets are small.

Examples

use sequoia_openpgp as openpgp;
use openpgp::parse::{Parse, stream::*};
use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

struct Helper {};
impl VerificationHelper for Helper {
    // ...
}
impl DecryptionHelper for Helper {
    // ...
}

let message =
    // ...

let h = Helper {};
let mut v = DecryptorBuilder::from_bytes(message)?
    .mapping(true)
    .with_policy(p, None, h)?;

pub fn with_policy<T, H>(
    self,
    policy: &'a dyn Policy,
    time: T,
    helper: H
) -> Result<Decryptor<'a, H>>where
    H: VerificationHelper + DecryptionHelper,
    T: Into<Option<SystemTime>>,

Creates the Decryptor.

Signature verifications are done under the given policy and relative to time time, or the current time, if time is None. helper is the VerificationHelper and DecryptionHelper to use.

Examples

use sequoia_openpgp as openpgp;
use openpgp::parse::{Parse, stream::*};
use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

struct Helper {};
impl VerificationHelper for Helper {
    // ...
}
impl DecryptionHelper for Helper {
    // ...
}

let message =
    // ...

let h = Helper {};
let mut v = DecryptorBuilder::from_bytes(message)?
    // Customize the `Decryptor` here.
    .with_policy(p, None, h)?;
