Functions

func CalculateHmac

func CalculateHmac(key, data []byte, algorithm string) (string, error)

calculates HMAC signature based on a key and digest algorithm supported digest algorithms are: SHA1, 256, 512

Types

type Rsa

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

func (*Rsa) Sign

func (x *Rsa) Sign(hashed []byte) ([]byte, error)

sign hashed data using private key

func (*Rsa) VerifySignature

func (x *Rsa) VerifySignature(hashed, signature []byte) error

verify hashed data using public key

type RsaScheme

type RsaScheme uint

const (
	PKCS1 RsaScheme = 1 + iota // https://en.wikipedia.org/wiki/PKCS_1
	PSS                        // https://en.wikipedia.org/wiki/Probabilistic_signature_scheme
