EchConfigList

Kotlin |Java

public class EchConfigList
extends Object

java.lang.Object
↳	android.net.ssl.EchConfigList

Data used to configure ECH (Encrypted Client Hello) in a TLS handshake.

This object can only be constructed by feeding in the raw bytes of the EchConfigList from a HTTPS DNS record (see https://datatracker.ietf.org/doc/html/rfc460), and may contain multiple EchConfigs.

The general structure starts with the length of the EchConfigList (2 bytes), then each entry in the list contains the following:

Version: 2 bytes
Length of the individual EchConfig: 2 bytes
Contents: unspecified number of bytes

See https://datatracker.ietf.org/doc/draft-ietf-tls-esni for details of the exact structure.

Summary

Public methods
`static EchConfigList`	`fromBytes(byte[] byteArr)` Factory method to construct a new [EchConfigList] from a byte array.
`byte[]`	`toBytes()` Returns the raw byte representation of an EchConfigList.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

fromBytes

public static EchConfigList fromBytes (byte[] byteArr)

Factory method to construct a new [EchConfigList] from a byte array.

The raw bytes from a HTTPS DNS record should be fed directly into this method.

Parameters
`byteArr`	`byte`: This value cannot be `null`.

Returns
`EchConfigList`	This value cannot be `null`.

Throws
`InvalidEchDataException`	if the ECH data is empty, does not contain a length, or has a length mismatch.
`NullPointerException`	if `byteArr` is null.

toBytes

public byte[] toBytes ()

Returns the raw byte representation of an EchConfigList.

Returns
`byte[]`	This value cannot be `null`.
