Struct sequoia_openpgp::crypto::mpis::MPI

pub struct MPI {
    pub bits: usize,
    pub value: Box<[u8]>,
}

Holds a single MPI.

Fields

bits: usize

Length of the integer in bits.

value: Box<[u8]>

Integer value as big-endian.

Methods

impl MPI

pub fn new(value: &[u8]) -> Self

Creates a new MPI.

This function takes care of leading zeros.

pub fn hash<H: Hash>(&self, hash: &mut H)

Update the Hash with a hash of the MPIs.

impl MPI

pub fn decode_point(&self, curve: &Curve) -> Result<(&[u8], &[u8])>

Dissects this MPI describing a point into the individual coordinates.

Errors

Returns Error::UnsupportedEllipticCurve if the curve is not supported, Error::InvalidArgument if the point is formatted incorrectly.

Trait Implementations

impl Serialize for MPI

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

Writes a serialized version of the packet to o.

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

Serializes the packet to a vector.

impl<'a> Parse<'a, MPI> for MPI

fn from_reader<R: Read>(reader: R) -> Result<Self>

Reads from the given reader.

fn from_file<P: AsRef<Path>>(path: P) -> Result<T>
