pub struct Token {

EWT Authentication Token

Fields

header: Header

payload: Payload

message_hash: [u8; 32]

The hashed value of the message: keccak256(header_json_base64.payload_json_base64)

signature: Vec<u8>

The signature after signing the message to_ethereum_signed(keccak256("{header_base64}.{payload_base64}")) The signature is in the form of {r}{s}{v}{mode} where mode is 01 for Ethereum Signature

token: String

Will result in authentication token string in the format of: {header_base64_encoded}.{payload_base64_encoded}.{signature_base64_encoded} All fields are base64 encoded

Implementations

impl Token

pub fn sign(
    signer: &SecretKey,
    payload: Payload
) -> Result<Self, EwtSigningError>

Signs a payload given a signer account & password. For the Header it uses ETH_HEADER.

Ethereum web token signing of payload with 1 difference: it’s not the JSON string representation that gets signed but the keccak256(payload_json).

pub fn verify(token: &str) -> Result<(Token, VerifyPayload), EwtVerifyError>

pub fn as_str(&self) -> &str

Returns the EWT Token string ready to be used in an Authentication header.

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Token

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Token

The EWT Token string is returned, ready to be used in an Authentication header.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Token> for Token

fn eq(&self, other: &Token) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
