A public key.

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

Note: This enum cannot be exhaustively matched to allow future extensions.

Variants

RSA

RSA public key.

Fields of RSA

e: MPI

Public exponent

n: MPI

Public modulo N = pq.

NIST DSA public key.

Fields of DSA

p: MPI

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

p: MPI

q: MPI

Public point.

ECDSA

NISTs Elliptic curve DSA public key.

Fields of ECDSA

curve: Curve

Fields of Unknown

mpis: Box<[MPI]>

The successfully parsed MPIs.

rest: Box<[u8]>

Any data that failed to parse.

Implementations

impl PublicKey[src]

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.
