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 semantics of each component. For information on the semantics, please see the relevant standards and RFCs.
Use the following include directive to get access to the records and constant macros described in the following sections.
-include_lib("public_key/include/public_key.hrl").
Common non-standard Erlang
