Functions

func ContainsString

func ContainsString(val string, vals []string) bool

Check if string is presnt in an array. Would use interface{} but whatever.

func JoinURL

func JoinURL(base, url string) string

func JsonSort

func JsonSort(what string) (string, error)

JsonSort decodes and re-encodes a json string to get a lexical sort on json keys. An error is returned if it's not in fact json.

func NewClock

func NewClock() *clock

func NewMockClock

func NewMockClock(unixNow int64) *mockClock

func ParsePubKey

func ParsePubKey(pubkey string) (crypto.PublicKey, error)

ParsePubKey

func ReadBodyRaw

func ReadBodyRaw(r *rest.Request) ([]byte, error)

func SerializePubKey

func SerializePubKey(key crypto.PublicKey) (string, error)

func UnixMilis

func UnixMilis() int64

func VerifyAuthReqSign

func VerifyAuthReqSign(signature string, pubkey crypto.PublicKey, content []byte) error

VerifyAuthReqSign verifies a SHA256 digested signature for a given public key. The current asymmetric crypto algorithms supported are RSA (PKCS 1.5 signature), ED25519 and ECDSA (DSA is considered obsolete). The signature is fixed to the SHA256 hash algorithm.

Types

type Clock

type Clock interface {
	Now() time.Time
	Forward(secs int64)
}
