Functions

func DigestAvaMsg

func DigestAvaMsg(msg string) []byte

Same algo as Avax wallet msg is the message, returns the hash of the full msg with prefix

func DoesNotInclude

func DoesNotInclude(strs []string, val string) bool

DoesNotInclude takes a slice of strings and a target string and returns TRUE if the slice does not include the target, FALSE if it does

Example:

x := DoesNotInclude([]string{"cat", "dog", "rat"}, "dog")
> false

x := DoesNotInclude([]string{"cat", "dog", "rat"}, "pig")
> true

func Dump

func Dump(obj interface{}) string

func EnsureFullPath

func EnsureFullPath(path string, mod os.FileMode)

EnsureFullPath ensures a directory exist from the given path.

func EnsurePath

func EnsurePath(path string, mod os.FileMode)

EnsurePath ensures a directory exist from the given path.

func Fatalf

func Fatalf(format string, args ...interface{})

Fatalf formats a message to standard error and exits the program. The message is also printed to standard output if standard error is redirected to a different file.

func FindMatch

func FindMatch(pattern string, data string) [][]string

FindMatch takes a regex pattern and a string of data and returns back all the matches in that string

func Includes

func Includes(strs []string, val string) bool

Includes takes a slice of strings and a target string and returns TRUE if the slice includes the target, FALSE if it does not

Example:

x := Includes([]string{"cat", "dog", "rat"}, "dog")
> true

x := Includes([]string{"cat", "dog", "rat"}, "pig")
> false

func MustGetUser

func MustGetUser() string

MustGetUser establishes current user identity or fail.

func PublicKeyFromAvaMsg

func PublicKeyFromAvaMsg(msg string, avasigcb58 string) (avacrypto.PublicKey, error)

Validate a msg signed with the Avalanche web wallet "Sign Message" feature

func ReadFileBytes

func ReadFileBytes(filePath string) ([]byte, error)

ReadFileBytes reads the contents of a file and returns those contents as a slice of bytes

func SigToRS

func SigToRS(sig mpsecdsa.Signature) (big.Int, big.Int)

Useful for using standard ecdsa funcs that require int args
