[][src]Struct sequoia_openpgp::crypto::mpi::ProtectedMPI

pub struct ProtectedMPI { /* fields omitted */ }

Holds a single MPI containing secrets.

The memory will be cleared when the object is dropped. Used by SecretKeyMaterial to protect secret keys.

Implementations

impl ProtectedMPI[src]

pub fn new_point(x: &[u8], y: &[u8], field_bits: usize) -> Self[src]

Creates new MPI encoding an uncompressed EC point.

Encodes the given point on a elliptic curve (see Section 6 of RFC 6637 for details). This is used to encode public keys and ciphertexts for the NIST curves (NistP256, NistP384, and NistP521).

pub fn new_compressed_point(x: &[u8]) -> Self[src]

Creates new MPI encoding a compressed EC point using native encoding.

Encodes the given point on a elliptic curve (see Section 13.2 of RFC4880bis for details). This is used to encode public keys and ciphertexts for the Bernstein curves (currently X25519).

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

Returns the length of the MPI in bits.

Leading zero-bits are not included in the returned size.

pub fn value(&self) -> &[u8][src]

Returns the value of this MPI.

Note that due to stripping of zero-bytes, the returned value may be shorter than expected.

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

Decodes an EC point encoded as MPI.

Decodes the MPI into a point on an elliptic curve (see Section 6 of RFC 6637 and Section 13.2 of RFC4880bis for details). If the point is not compressed, the function returns (x, y). If it is compressed, y will be empty.

Errors

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