Supported hash algorithms

func (Algorithm) CryptoHash

func (a Algorithm) CryptoHash() crypto.Hash

CryptoHash returns the crypto.Hash implementation for the given HashAlgorithm

func (Algorithm) Digest

func (a Algorithm) Digest(b []byte) []byte

Digest performs a digest on the passed value

func (Algorithm) Insecure

func (a Algorithm) Insecure() bool

Insecure returns if the given HashAlgorithm is considered secure in DTLS 1.2

func (Algorithm) String

func (a Algorithm) String() string

String makes hashAlgorithm printable
