# [−][src]Enum sequoia_openpgp::crypto::mpis::PublicKey

Holds a public key.

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

## Variants

`RSA`

RSA public key.

### Fields of **RSA**

`DSA`

NIST DSA public key.

### Fields of **DSA**

`ElGamal`

ElGamal public key.

### Fields of **ElGamal**

`EdDSA`

DJBs "Twisted" Edwards curve DSA public key.

### Fields of **EdDSA**

`ECDSA`

NISTs Elliptic curve DSA public key.

### Fields of **ECDSA**

`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**

## Methods

`impl PublicKey`

[src]

`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.
