Implementations

impl Mpi

pub fn new(value: mpi_sint) -> Result<Mpi>

pub fn from_binary(num: &[u8]) -> Result<Mpi>

Initialize an MPI number from big endian binary data

pub fn get_bit(&self, bit: usize) -> bool

pub fn set_bit(&mut self, bit: usize, val: bool) -> Result<()>

pub fn less_than_const_time(&self, other: &Mpi) -> Result<bool>

Checks if an Mpi is less than the other in constant time.

Will return Error::MpiBadInputData if the allocated length of the two input Mpis is not the same.

pub fn cmp_const_time(&self, other: &Mpi) -> Result<Ordering>

Compares an Mpi with the other in constant time.

Will return Error::MpiBadInputData if the allocated length of the two input Mpis is not the same.

pub fn eq_const_time(&self, other: &Mpi) -> Result<bool>

Checks equalness with the other in constant time.

pub fn as_u32(&self) -> Result<u32>

pub fn sign(&self) -> Sign

pub fn bit_length(&self) -> Result<usize>

Return size of this MPI in bits

pub fn byte_length(&self) -> Result<usize>

Return size of this MPI in bytes (rounded up)

pub fn divrem(&self, other: &Mpi) -> Result<(Mpi, Mpi)>

Reduce self modulo other

pub fn divrem_int(&self, other: mpi_sint) -> Result<(Mpi, Mpi)>

pub fn modinv(&self, modulus: &Mpi) -> Result<Mpi>

pub fn mod_sqrt(&self, p: &Mpi) -> Result<Mpi>

Returns an integer a such that (a*a) === self (mod p)

The modulus must be prime; computing a square root modulo a composite number is equivalent to factoring the composite.

Calculates Jacobi symbol (self|N)

pub fn mod_exp(&self, exponent: &Mpi, modulus: &Mpi) -> Result<Mpi>

pub fn is_probably_prime<F: Random>(&self, k: u32, rng: &mut F) -> Result<()>

The Miller-Rabin primality test with k rounds. Returns MpiNotAcceptable if self is definitely not prime. If no error is returned, self is prime with a probability of 1 - 1/2^{2k}. See mbedtls_mpi_is_prime.
