Implementations

impl CipherMethod

pub fn parse_method(s: &str) -> Result<Self, ShadowsocksError>

Parse a method name string into a CipherMethod.

pub fn key_size(&self) -> usize

Key size in bytes.

pub fn salt_size(&self) -> usize

Salt/IV size in bytes.

pub fn nonce_size(&self) -> usize

Nonce size in bytes.

pub fn tag_size(&self) -> usize

Authentication tag size in bytes.

pub fn derive_key( &self, password: &[u8], salt: &[u8], ) -> Result<Vec<u8>, ShadowsocksError>

Derive an AEAD subkey from password and salt using HKDF-SHA1.

Uses EVP_BytesToKey(password) as IKM (matching OpenSSL/shadowsocks-rust), truncated to key_size bytes, then HKDF-SHA1 with info=“ss-subkey” per SIP003.
