Functions ¶

func Algorithms ¶

func Algorithms() map[Algorithm]struct{}

Algorithms returns all the supported Hash Algorithms.

Types ¶

type Algorithm ¶

type Algorithm uint16

Algorithm is used to indicate the hash algorithm used https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-18

const (
	None    Algorithm = 0 // Blacklisted
	MD5     Algorithm = 1 // Blacklisted

	SHA512  Algorithm = 6
	Ed25519 Algorithm = 8
)

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.
