Implementations

impl Cipher

pub fn new(kind: CipherKind, key: &[u8], iv_or_salt: &[u8]) -> Cipher

Create a new Cipher of kind

• Stream Ciphers initialize with IV
• AEAD Ciphers initialize with SALT

pub fn category(&self) -> CipherCategory

Get the CipherCategory of the current cipher

pub fn kind(&self) -> CipherKind

Get the CipherKind of the current cipher

pub fn tag_len(&self) -> usize

Get the TAG length of AEAD ciphers

pub fn encrypt_packet(&mut self, pkt: &mut [u8])

Encrypt a packet. Encrypted result will be written in pkt

• Stream Ciphers: the size of input and output packets are the same
• AEAD Ciphers: the size of output must be at least input.len() + TAG_LEN

#[must_use]

pub fn decrypt_packet(&mut self, pkt: &mut [u8]) -> bool

Decrypt a packet. Decrypted result will be written in pkt

• Stream Ciphers: the size of input and output packets are the same
• AEAD Ciphers: the size of output is input.len() - TAG_LEN
