Holds a public key.

Provides a typed and structured way of storing multiple MPIs (and the occasional elliptic curve) in packets.

Variants

Prime of the ring Zp.

q: MPI

Order of g in Zp.

g: MPI

Public generator of Zp.

y: MPI

Public key g^x mod p.

Elgamal

Elgamal public key.

Fields of Elgamal

Generator of Zp.

y: MPI

Public key g^x mod p.

EdDSA

Public point.

ECDSA

NISTs Elliptic curve DSA public key.

Fields of ECDSA

curve: Curve

Curve we're using.

q: MPI

Public point.

ECDH

Elliptic curve Elgamal public key.

Fields of ECDH

curve: Curve

Curve we're using.

q: MPI

Public point.

hash: HashAlgorithm

Hash algorithm used for key derivation.

sym: SymmetricAlgorithm

Algorithm used w/the derived key.

Unknown

Unknown number of MPIs for an unknown algorithm.

Fields of Unknown

mpis: Box<[MPI]>

The successfully parsed MPIs.

rest: Box<[u8]>

Methods

impl PublicKey[src]

pub fn keygrip(&self) -> Result<Keygrip>[src]

Computes the keygrip.

impl PublicKey[src]

pub fn serialized_len(&self) -> usize[src]

Number of octets all MPIs of this instance occupy when serialized.

pub fn bits(&self) -> Option<usize>[src]

Returns the length of the public key in bits.

For finite field crypto this returns the size of the field we operate in, for ECC it returns Curve::bits().

Note: This information is useless and should not be used to gauge the security of a particular key. This function exists only because some legacy PGP application like HKP need it.

Returns None for unknown keys and curves.

pub fn algo(&self) -> Option<PublicKeyAlgorithm>[src]

Returns, if known, the public-key algorithm for this public key.

impl PublicKey[src]

pub fn parse<T: AsRef<[u8]>>(algo: PublicKeyAlgorithm, buf: T) -> Result<Self>[src]

Parses a set of OpenPGP MPIs representing a public key.

See Section 3.2 of RFC 4880 for details.
