Enum sequoia_openpgp::crypto::mpi::Ciphertext

#[non_exhaustive]
pub enum Ciphertext {
    RSA {
        c: MPI,
    },
    ElGamal {

}

An encrypted session key.

Provides a typed and structured way of storing multiple MPIs in PKESK packets.

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

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RSA

RSA ciphertext.

Fields

c: MPI

m^e mod N.

ElGamal

ElGamal ciphertext.

Fields

e: MPI

Ephemeral key.

c: MPI

Ciphertext.

ECDH

Elliptic curve ElGamal public key.

Fields

e: MPI

Ephemeral key.

key: Box<[u8]>

Symmetrically encrypted session key.

Unknown

Unknown number of MPIs for an unknown algorithm.

Fields

mpis: Box<[MPI]>

The successfully parsed MPIs.

rest: Box<[u8]>

Any data that failed to parse.

Implementations

impl Ciphertext

pub fn pk_algo(&self) -> Option<PublicKeyAlgorithm>

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

impl Ciphertext

pub fn parse<R: Read + Send + Sync>( algo: PublicKeyAlgorithm, reader: R ) -> Result<Self>

Parses a set of OpenPGP MPIs representing a ciphertext.

Expects MPIs for a public key algorithm algos ciphertext. See Section 3.2 of RFC 4880 for details.

Trait Implementations

impl Clone for Ciphertext

fn clone(&self) -> Ciphertext

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Ciphertext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Ciphertext

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Hash for Ciphertext

fn hash(&self, hash: &mut dyn Digest)

Updates the given hash with this object.

impl Marshal for Ciphertext

fn serialize(&self, w: &mut dyn Write) -> Result<()>

Writes a serialized version of the object to o.

fn export(&self, o: &mut dyn Write) -> Result<()>

Exports a serialized version of the object to o.

impl MarshalInto for Ciphertext

fn serialized_len(&self) -> usize

Computes the maximal length of the serialized representation.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize>

Serializes into the given buffer.

fn to_vec(&self) -> Result<Vec<u8>>

Serializes the packet to a vector.

fn export_into(&self, buf: &mut [u8]) -> Result<usize>

Exports into the given buffer.

fn export_to_vec(&self) -> Result<Vec<u8>>

Exports to a vector.

impl Ord for Ciphertext

fn cmp(&self, other: &Ciphertext) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Ciphertext

fn eq(&self, other: &Ciphertext) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &Ciphertext) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
