<h1>2 Public key records</h1>
  
    
  <p>This chapter briefly describes Erlang records derived from asn1
  specifications used to handle public and private keys. The intent
  is to describe the data types and not to specify the meaning of
  each component for this we refer you to the relevant standards and RFCs.</p>

  <p>Use the following include directive to get access to the
  records and constant macros used in the following sections.</p>
  
  <div class="example"><pre> -include_lib("public_key/include/public_key.hrl"). </pre></div>
