§Packet module

Handles everything in relationship to packets.

Key generation is handled separately as well as signing and verifying with external hashing applied.

use pgp::crypto::{self, sym::SymmetricKeyAlgorithm, hash::HashAlgorithm, public_key::PublicKeyAlgorithm};
use pgp::types::{self, PublicKeyTrait, SecretKeyTrait, CompressionAlgorithm};
use smallvec::*;
use pgp::packet::{Signature, SignatureConfig};

let signing_key = signed_secret_key;
let verification_key = public_key;


let passwd_fn = || String::new();

let now = chrono::Utc::now();

let mut sig_cfg = SignatureConfig::v4(packet::SignatureType::Binary, PublicKeyAlgorithm::RSA, HashAlgorithm::SHA2_256);
sig_cfg.hashed_subpackets = vec![
    packet::Subpacket::regular(packet::SubpacketData::SignatureCreationTime(now)),
    packet::Subpacket::regular(packet::SubpacketData::Issuer(signing_key.key_id())),
];

let signature_packet = sig_cfg
     .sign(&signing_key, passwd_fn, DATA)
     .expect("Should sign");

let mut signature_bytes = Vec::with_capacity(1024);
packet::write_packet(&mut signature_bytes, &signature_packet).expect("Write must succeed");

signature_packet
     .verify(&verification_key, DATA)
     .expect("Failed to validate signature");
