Struct DetachedVerifierBuilder 

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

A builder for DetachedVerifier.

This allows the customization of DetachedVerifier, which can be built using DetachedVerifierBuilder::with_policy.

Implementations

impl<'a> DetachedVerifierBuilder<'a>

pub fn mapping(self, enabled: bool) -> DetachedVerifierBuilder<'a>

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 {
    // ...
}

let signature =
    // ...

let h = Helper {};
let mut v = DetachedVerifierBuilder::from_bytes(&signature[..])?
    .mapping(true)
    .with_policy(p, None, h)?;

pub fn with_policy<T, H>( self, policy: &'a dyn Policy, time: T, helper: H, ) -> Result<DetachedVerifier<'a, H>, Error>

where H: VerificationHelper, T: Into<Option<SystemTime>>,

Creates the DetachedVerifier.

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 to use. VerificationHelper::check will be called with a MessageStructure containing exactly one layer, a signature group.

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 {
    // ...
}

let signature =
    // ...

let h = Helper {};
let mut v = DetachedVerifierBuilder::from_bytes(&signature[..])?
    // Customize the `DetachedVerifier` here.
    .with_policy(p, None, h)?;
