`Attestation.decode`

Decode an attestation

Decodes an attestation without verifying it. Use it to read the audience, issuer, type, or expiry; use Attestation.verify before trusting any claim.

Usage

import * as  from 'mppx/extensions/identity/attestation'
 
declare const : string
 
const  = .() 
.(?..)

  header: { alg?: unknown; kid?: unknown; typ?: unknown }
  signature: Uint8Array
  signingInput: Uint8Array // base64url(header) + '.' + base64url(claims)
} | undefined

Returns undefined when the token is longer than 8192 characters, doesn't have three base64url parts, or its header or claims aren't JSON objects.
