Struct sequoia_openpgp::cert::KeyBuilder[][src]

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

A Key builder.

A KeyBuilder is used to create a key, which can then be attached to an existing certificate as a subkey using KeyBuilder::subkey.

Examples

Generate a signing key and attach it to a certificate:

use sequoia_openpgp as openpgp;
use openpgp::cert::prelude::*;
use openpgp::policy::StandardPolicy;
use openpgp::types::KeyFlags;

let p = &StandardPolicy::new();

let vc = cert.with_policy(p, None)?;
let cert_new = KeyBuilder::new(KeyFlags::empty().set_signing())
    .subkey(vc)?
    .attach_cert()?;

Implementations

Returns a new KeyBuilder.

Use KeyBuilder::subkey to generate a subkey and get a SubkeyBuilder, which can be used to add the subkey to a certificate.

Returns the selected cipher suite.

Sets the cipher suite.

Returns the creation time.

Returns None if the creation time hasn’t been specified. In that case, the creation time will be set to the current time when the key material is generated by KeyBuilder::subkey.

Sets the creation time.

If None, then the creation time will be set to the current time when the key material is generated by KeyBuilder::subkey.

Returns the password, if any.

Sets the password.

Generates a key, and returns a SubkeyBuilder.

The SubkeyBuilder will add the key to the specified certificate.

If the key creation time has not been explicitly set using KeyBuilder::set_creation_time, then the key’s creation time is set to the current time minus a few seconds.

Setting the creation time to a short time in the past solves two problems. First, when a new binding signature is created, it must have a newer time than the previous binding signature. This policy ensures that if a second binding signature is immediately created after the key is created it does not need to be postdated and thus can be used immediately. Second, if the key is immediately transferred to another computer and its clock is not quite synchronized, the key may appear to have been created in the future and will thus be ignored. Although NTP is widely used, emperically it seems that some virtual machines have laggy clocks.
