Struct poseidon252::encrypt::EncryptedData

pub struct EncryptedData { /* fields omitted */ }

Encapsulates an encrypted data

Implementations

impl EncryptedData

pub fn encrypt(
    message: &BlsScalar,
    secret: &BlsScalar,
    nonce: &BlsScalar
) -> Self

Perform the encryption of a given message provided a secret and a nonce

pub fn decrypt(
    &self,
    secret: &BlsScalar,
    nonce: &BlsScalar
) -> Option<BlsScalar>

Decrypt a previously encrypted message, provided the shared secret and nonce used for encryption. If the decryption is not successful, None is returned

Trait Implementations

impl Clone for EncryptedData

fn clone(&self) -> EncryptedData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for EncryptedData

impl Debug for EncryptedData

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

Formats the value using the given formatter.

impl Eq for EncryptedData

impl PartialEq<EncryptedData> for EncryptedData

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

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

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

This method tests for !=.

impl Read for EncryptedData

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl StructuralEq for EncryptedData

impl StructuralPartialEq for EncryptedData

impl Write for EncryptedData

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

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<(), Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writeer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice]) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Write.
