Certificate records Ingela Anderton Andin 2008-02-06 A cert_records.xml

This chapter briefly describes erlang records derived from asn1 specifications used to handle X509 certificates. The intent is to describe the data types and not to specify the meaning of each component for this we refer you to RFC 5280.

Use the following include directive to get access to the records and constant macros (OIDs) described in the following sections.

-include_lib("public_key/include/public_key.hrl").

The used asn1 specifications are available asn1 subdirectory of the application public_key.

Common Data Types

Common non standard erlang data types used to described the record fields in the below sections are defined in public key reference manual or follows here.

oid() - a tuple of integers as generated by the asn1 compiler.

time() = uct_time() | general_time()

uct_time() = {utcTime, "YYMMDDHHMMSSZ"}

general_time() = {generalTime, "YYYYMMDDHHMMSSZ"}

general_name() = {rfc822Name, string()} | {dNSName, string()} | {x400Address, string()} | {directoryName, {rdnSequence, [#AttributeTypeAndValue'{}]}} | | {eidPartyName, special_string()} | {eidPartyName, special_string(), special_string()} | {uniformResourceIdentifier, string()} | {ipAddress, string()} | {registeredId, oid()} | {otherName, term()}

special_string() = {teletexString, string()} | {printableString, string()} | {universalString, string()} | {utf8String, string()} | {bmpString, string()}
