DtlsTicketKeyManager.ticketAad

private

ubyte[] ticketAad(uint  lifetimeSeconds,
           size_t maxEarlyData,  ushort  cipherSuite)

static @safe pure nothrow

Builds the additional authenticated data binding a ticket's cleartext metadata to its ciphertext.

The metadata travels in the clear inside DtlsEncryptedTicket; authenticating it prevents an attacker from altering the lifetime, early-data limit or cipher suite of an issued ticket.

Parameters

`lifetimeSeconds`	Ticket lifetime hint.
`maxEarlyData`	Maximum early data size.
`cipherSuite`	Negotiated cipher suite ID.

Returns

14 bytes of big-endian metadata.
