go-fingerprint

This is a simple interface, which wraps github.com/minio/highwayhash to allow fingerprinting for any object that implements the Stringer interface. This allows for server side finger printing of structs created by server request payloads.

func Identify

func Identify(strObjects ...fmt.Stringer) (string, error)

Identify takes the string representation of objects and creates a hash in the form of a uuid if a seed is not provided a random 32 byte key is generated using a timestamp

func SetHashKeyWithSeed

func SetHashKeyWithSeed(s int64)

SetHashKeyWithSeed sets the seed and generates a new 32 key for the internal hash function

type Scanner

type Scanner struct {
    // contains filtered or unexported fields
}

Scanner provides the ability to create a single hash.Hash that can be reused

func NewScanner

func NewScanner() Scanner

NewScanner returns an instance of scanner with the hash initialized using the math/rand package

func (Scanner) Identify

func (sc Scanner) Identify(strObjects ...fmt.Stringer) (string, error)

func (*Scanner) SetHashKeyWithSeed

func (sc *Scanner) SetHashKeyWithSeed(s int64)

SetHashKeyWithSeed sets the seed and generates a new 32 key for the internal hash function note that this is not protected by a mutex for performance reasons

type Stringer

type Stringer string

Stringer is a type alias for the string primitive that allows normal strings to satisfy the fmt.Stringer interface

func (Stringer) String

func (s Stringer) String() string
