Implementations§

source§

impl<O, N> Tsig<O, N>

source

pub fn new( algorithm: N, time_signed: Time48, fudge: u16, mac: O, original_id: u16, error: TsigRcode, other: O, ) -> Result<Self, LongRecordData>
where O: AsRef<[u8]>, N: ToDname,

Creates new TSIG record data from its components.

See the access methods for an explanation of these components. The function will return an error if the wire format length of the record would exceed 65,535 octets.

source

pub unsafe fn new_unchecked( algorithm: N, time_signed: Time48, fudge: u16, mac: O, original_id: u16, error: TsigRcode, other: O, ) -> Self

Creates new TSIG record data without checking.

§Safety

The caller needs to ensure that the wire format length of the created record will not exceed 65,535 octets.

source

pub fn algorithm(&self) -> &N

Returns a reference to the algorithm name.

TSIG encodes the algorithm used for keys and signatures as a domain name. It does, however, only use the format. No structure is used at all.

source

pub fn time_signed(&self) -> Time48

Returns the Unix time when the signature is created.

Despite its type, this is actually a 48 bit number. The upper 16 bits will never be set.

source

pub fn fudge(&self) -> u16

Return the number of seconds of offset from signing time permitted.

When a signature is checked, the local system time needs to be within this many seconds from time_signed to be accepted.

source

pub fn mac(&self) -> &O

Returns a reference to the bytes value containing the MAC.

source

pub fn mac_slice(&self) -> &[u8]
where O: AsRef<[u8]>,

Returns an octet slice containing the MAC.

source

pub fn into_mac(self) -> O

Converts the record data into the MAC.

source

pub fn original_id(&self) -> u16

Returns the original message ID.

Since the message ID is part of the signature generation but may be changed for a forwarded message, it is included in the TSIG record.

source

pub fn error(&self) -> TsigRcode

Returns the TSIG error.

source

pub fn other(&self) -> &O

Returns a reference to the other bytes.

This field is only used for BADTIME errors to return the server time. Otherwise it is empty.

source

pub fn other_time(&self) -> Option<Time48>
where O: AsRef<[u8]>,

Returns the other bytes as the server time.

If the other bytes field is exactly 6 bytes long, this methods returns it as a u64 representation of the Unix time contained.

source

pub fn is_valid_at(&self, now: Time48) -> bool

Returns whether the record is valid at the given time.

The method checks whether the given time is within fudge seconds of the time_signed.

source

pub fn is_valid_now(&self) -> bool

Returns whether the record is valid right now.

The method checks whether the current system time is within fudge seconds of the time_signed.
