Struct SchmidtSamoaPublicKey 

pub struct SchmidtSamoaPublicKey { /* private fields */ }

Public key for the Schmidt-Samoa primitive.

Implementations

impl SchmidtSamoaPublicKey

pub fn modulus(&self) -> &BigUint

Return the public modulus n = p^2 q.

pub fn max_plaintext_exclusive(&self) -> BigUint

Return a conservative public upper bound for byte-oriented plaintexts.

For n = p^2 q, the private reduction modulus gamma = p q always satisfies gamma > floor(sqrt(n)), so any message below this bound is guaranteed to round-trip through the private map.

pub fn encrypt_raw(&self, message: &BigUint) -> BigUint

Apply the raw public map m^n mod n.

Unlike textbook RSA, the public exponent is the modulus n itself. The inverse map recovers the original message only for values interpreted in the range [0, gamma), where gamma = p q.

pub fn encrypt(&self, message: &[u8]) -> Option<BigUint>

Encrypt a byte string using the conservative public plaintext bound.

pub fn encrypt_bytes(&self, message: &[u8]) -> Option<Vec<u8>>

Encrypt a byte string and return the serialized ciphertext bytes.

pub fn to_key_blob(&self) -> Vec<u8>

Encode the public key in the crate-defined binary format.

pub fn from_key_blob(blob: &[u8]) -> Option<Self>

Decode the public key from the crate-defined binary format.

pub fn to_pem(&self) -> String

Encode the public key in PEM using the crate-defined label.

pub fn to_xml(&self) -> String

Encode the public key as the crate’s flat XML form.

pub fn from_pem(pem: &str) -> Option<Self>

Decode the public key from the crate-defined PEM label.

pub fn from_xml(xml: &str) -> Option<Self>

Decode the public key from the crate’s flat XML form.

Trait Implementations

impl Clone for SchmidtSamoaPublicKey

fn clone(&self) -> SchmidtSamoaPublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchmidtSamoaPublicKey

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

Formats the value using the given formatter.

impl PartialEq for SchmidtSamoaPublicKey

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

Tests for self and other values to be equal, and is used by ==.

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

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