Struct wow_srp::wrath_header::ServerCrypto

pub struct ServerCrypto { /* private fields */ }

Available on crate feature wrath-header only.

Main struct for encryption or decryption.

Created from ProofSeed::into_server_header_crypto.

Handles both encryption and decryption of headers through the ServerEncrypterHalf and ServerDecrypterHalf structs.

Can be split into a ServerEncrypterHalf and ServerDecrypterHalf through the ServerCrypto::split method. This is useful if you have this struct behind a mutex and don’t want to lock both reading and writing at the same time.

Implementations

impl ServerCrypto

pub fn decrypter(&mut self) -> &mut ServerDecrypterHalf

Direct access to the internal ServerDecrypterHalf.

pub fn encrypter(&mut self) -> &mut ServerEncrypterHalf

Direct access to the internal ServerEncrypterHalf.

pub fn encrypt(&mut self, data: &mut [u8])

Raw access to the encryption.

Use either the server Write function, or the server array function.

pub fn write_encrypted_server_header<W: Write>( &mut self, write: W, size: u32, opcode: u16 ) -> Result<()>

Convenience wrapper for ServerEncrypterHalf::write_encrypted_server_header.

Errors

Has the same errors as ServerEncrypterHalf::write_encrypted_server_header.

pub fn encrypt_server_header(&mut self, size: u32, opcode: u16) -> &[u8]

Convenience wrapper for ServerEncrypterHalf::encrypt_server_header.

pub fn decrypt(&mut self, data: &mut [u8])

Raw access to decryption.

Use either the server Read function, or the server array functions.

pub fn read_and_decrypt_client_header<R: Read>( &mut self, reader: R ) -> Result<ClientHeader>

Convenience wrapper for ServerDecrypterHalf::read_and_decrypt_client_header.

Errors

Has the same errors as ServerDecrypterHalf::read_and_decrypt_client_header.

pub fn decrypt_client_header(&mut self, data: [u8; 6]) -> ClientHeader

Convenience wrapper for ServerDecrypterHalf::decrypt_client_header.

Prefer this over directly using Self::decrypt.

pub fn split(self) -> (ServerEncrypterHalf, ServerDecrypterHalf)

Split the ServerCrypto into two parts for use with split connections.

It is intended for the ServerEncrypterHalf to be stored with the write half of the connection and for the ServerDecrypterHalf to be stored with the read half of the connection.

This is not necessary to do unless you actually can split your connections into read and write halves, and you have some reason for not just keeping the crypto together like if you don’t want locking encryption to also lock decryption in a mutex.

Trait Implementations

impl Clone for ServerCrypto

fn clone(&self) -> ServerCrypto

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ServerCrypto

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

Formats the value using the given formatter.

impl Hash for ServerCrypto

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ServerCrypto

fn cmp(&self, other: &ServerCrypto) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ServerCrypto

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

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

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

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

impl PartialOrd for ServerCrypto

fn partial_cmp(&self, other: &ServerCrypto) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
