Struct sequoia_openpgp::packet::key::Key4

source ·
pub struct Key4<P, R>
where P: KeyParts, R: KeyRole,
{ /* private fields */ }
Expand description

Holds a public key, public subkey, private key or private subkey packet.

Use Key4::generate_rsa or Key4::generate_ecc to create a new key.

Existing key material can be turned into an OpenPGP key using Key4::new, Key4::with_secret, Key4::import_public_cv25519, Key4::import_public_ed25519, Key4::import_public_rsa, Key4::import_secret_cv25519, Key4::import_secret_ed25519, and Key4::import_secret_rsa.

Whether you create a new key or import existing key material, you still need to create a binding signature, and, for signing keys, a back signature before integrating the key into a certificate.

Normally, you won’t directly use Key4, but Key, which is a relatively thin wrapper around Key4.

See Section 5.5 of RFC 4880 and the documentation for Key for more details.

impl<P, R> Key4<P, R>
where P: KeyParts, R: KeyRole,

source

pub fn hash_algo_security(&self) -> HashAlgoSecurity

The security requirements of the hash algorithm for self-signatures.

A cryptographic hash algorithm usually has three security properties: pre-image resistance, second pre-image resistance, and collision resistance. If an attacker can influence the signed data, then the hash algorithm needs to have both second pre-image resistance, and collision resistance. If not, second pre-image resistance is sufficient.

In general, an attacker may be able to influence third-party signatures. But direct key signatures, and binding signatures are only over data fully determined by signer. And, an attacker’s control over self signatures over User IDs is limited due to their structure.

These observations can be used to extend the life of a hash algorithm after its collision resistance has been partially compromised, but not completely broken. For more details, please refer to the documentation for HashAlgoSecurity.

source

pub fn public_cmp<PB, RB>(&self, b: &Key4<PB, RB>) -> Ordering
where PB: KeyParts, RB: KeyRole,

source

This is an alternate implementation of Hash, which never hashes the secret key material.

Creates a new OpenPGP secret key packet for an existing X25519 key.

The ECDH key will use hash algorithm hash and symmetric algorithm sym. If one or both are None secure defaults will be used. The key will have it’s creation date set to ctime or the current time if None is given.

The given private_key is expected to be in the native X25519 representation, i.e. as opaque byte string of length 32. It is transformed into OpenPGP’s representation during import.

pub fn generate_ecc(for_signing: bool, curve: Curve) -> Result<Self>

Generates a new ECC key over curve.

If for_signing is false a ECDH key, if it’s true either a EdDSA or ECDSA key is generated. Giving for_signing == true and curve == Cv25519 will produce an error. Likewise for_signing == false and curve == Ed25519 will produce an error.

source

pub fn generate_dsa(p_bits: usize) -> Result<Self>

Generates a new DSA key with a public modulus of size p_bits.

Note: In order to comply with FIPS 186-4, and to increase compatibility with implementations, you SHOULD only generate keys with moduli of size 2048 or 3072 bits.

source

pub fn generate_elgamal(p_bits: usize) -> Result<Self>

Generates a new ElGamal key with a public modulus of size p_bits.
