Implementations§

source§

impl TsigAlgorithm

source

pub fn to_name(&self) -> Name

Return DNS name for the algorithm

source

pub fn emit(&self, encoder: &mut BinEncoder<'_>) -> ProtoResult<()>

Write the Algorithm to the given encoder

source

pub fn read(decoder: &mut BinDecoder<'_>) -> ProtoResult<Self>

Read the Algorithm from the given Encoder

source

pub fn from_name(name: Name) -> Self

Convert a DNS name to an Algorithm

source

pub fn mac_data(&self, key: &[u8], message: &[u8]) -> ProtoResult<Vec<u8>>

Available on crate feature dnssec-ring only.

Compute the Message Authentication Code using key and algorithm

Supported algorithm are HmacSha256, HmacSha384, HmacSha512 and HmacSha512_256 Other algorithm return an error.

source

pub fn verify_mac( &self, key: &[u8], message: &[u8], tag: &[u8], ) -> ProtoResult<()>

Available on crate feature dnssec-ring only.

Verifies the hmac tag against the given key and this algorithm.

This is both faster than independently creating the MAC and also constant time preventing timing attacks

source

pub fn output_len(&self) -> ProtoResult<usize>

Available on crate feature dnssec-ring only.

Return length in bytes of the algorithms output

source

pub fn supported(&self) -> bool

Return true if cryptographic operations needed for using this algorithm are supported, false otherwise

§Supported
  • HmacSha256
  • HmacSha384
  • HmacSha512
  • HmacSha512_256
