  • file (String) —

    • The file

  • hashing (Symbol) (defaults to: :sha256) —

    • An hashing type (md5, sha1, sha256, sha3-256, sha3-512)

  • multisig (Boolean) (defaults to: false) —

    • true if transaction is multisig, false otherwise

  • signed (Symbol) (defaults to: false) —

    • true if apostille is private / transferable / updateable, false if public
