Appendix A.  Pseudo-ASN.1 Structures and OIDs

   This section describes data objects used by conforming PKI components
   in an "ASN.1-like" syntax.  This syntax is a hybrid of the 1988 and
   1993 ASN.1 syntaxes.  The 1988 ASN.1 syntax is augmented with 1993
   UNIVERSAL Types UniversalString, BMPString and UTF8String.

   The ASN.1 syntax does not permit the inclusion of type statements in
   the ASN.1 module, and the 1993 ASN.1 standard does not permit use of
   the new UNIVERSAL types in modules using the 1988 syntax.  As a
   result, this module does not conform to either version of the ASN.1
   standard.

   This appendix may be converted into 1988 ASN.1 by replacing the
   definitions for the UNIVERSAL Types with the 1988 catch-all "ANY".

Appendix B.  ASN.1 Notes

   CAs MUST force the serialNumber to be a non-negative integer, that
   is, the sign bit in the DER encoding of the INTEGER value MUST be
   zero - this can be done by adding a leading (leftmost) `00'H octet if
   necessary.  This removes a potential ambiguity in mapping between a
   string of octets and an integer value.

   As noted in section 4.1.2.2, serial numbers can be expected to
   contain long integers.  Certificate users MUST be able to handle
   serialNumber values up to 20 octets in length.  Conformant CAs MUST
   NOT use serialNumber values longer than 20 octets.

   As noted in section 5.2.3, CRL numbers can be expected to contain
   long integers.  CRL validators MUST be able to handle cRLNumber
   values up to 20 octets in length.  Conformant CRL issuers MUST NOT
   use cRLNumber values longer than 20 octets.

Top      Up      ToC       Page 113 
   The construct "SEQUENCE SIZE (1..MAX) OF" appears in several ASN.1
   constructs.  A valid ASN.1 sequence will have zero or more entries.
   The SIZE (1..MAX) construct constrains the sequence to have at least
   one entry.  MAX indicates the upper bound is unspecified.
   Implementations are free to choose an upper bound that suits their
   environment.

   The construct "positiveInt ::= INTEGER (0..MAX)" defines positiveInt
   as a subtype of INTEGER containing integers greater than or equal to
   zero.  The upper bound is unspecified.  Implementations are free to
   select an upper bound that suits their environment.

   The character string type PrintableString supports a very basic Latin
   character set: the lower case letters 'a' through 'z', upper case
   letters 'A' through 'Z', the digits '0' through '9', eleven special
   characters ' = ( ) + , - . / : ? and space.

   Implementers should note that the at sign ('@') and underscore ('_')
   characters are not supported by the ASN.1 type PrintableString.
   These characters often appear in internet addresses.  Such addresses
   MUST be encoded using an ASN.1 type that supports them.  They are
   usually encoded as IA5String in either the emailAddress attribute
   within a distinguished name or the rfc822Name field of GeneralName.
   Conforming implementations MUST NOT encode strings which include
   either the at sign or underscore character as PrintableString.

   The character string type TeletexString is a superset of
   PrintableString.  TeletexString supports a fairly standard (ASCII-
   like) Latin character set, Latin characters with non-spacing accents
   and Japanese characters.

   Named bit lists are BIT STRINGs where the values have been assigned
   names.  This specification makes use of named bit lists in the
   definitions for the key usage, CRL distribution points and freshest
   CRL certificate extensions, as well as the freshest CRL and issuing
   distribution point CRL extensions.  When DER encoding a named bit
   list, trailing zeroes MUST be omitted.  That is, the encoded value
   ends with the last named bit that is set to one.

   The character string type UniversalString supports any of the
   characters allowed by ISO 10646-1 [ISO 10646].  ISO 10646-1 is the
   Universal multiple-octet coded Character Set (UCS).  ISO 10646-1
   specifies the architecture and the "basic multilingual plane" -- a
   large standard character set which includes all major world character
   standards.

Top      Up      ToC       Page 114 
   The character string type UTF8String was introduced in the 1997
   version of ASN.1, and UTF8String was added to the list of choices for
   DirectoryString in the 2001 version of X.520 [X.520].  UTF8String is
   a universal type and has been assigned tag number 12.  The content of
   UTF8String was defined by RFC 2044 [RFC 2044] and updated in RFC 2279
   [RFC 2279].

   In anticipation of these changes, and in conformance with IETF Best
   Practices codified in RFC 2277 [RFC 2277], IETF Policy on Character
   Sets and Languages, this document includes UTF8String as a choice in
   DirectoryString and the CPS qualifier extensions.

   Implementers should note that the DER encoding of the SET OF values
   requires ordering of the encodings of the values.  In particular,
   this issue arises with respect to distinguished names.

   Implementers should note that the DER encoding of SET or SEQUENCE
   components whose value is the DEFAULT omit the component from the
   encoded certificate or CRL.  For example, a BasicConstraints
   extension whose cA value is FALSE would omit the cA boolean from the
   encoded certificate.

   Object Identifiers (OIDs) are used throughout this specification to
   identify certificate policies, public key and signature algorithms,
   certificate extensions, etc.  There is no maximum size for OIDs.
   This specification mandates support for OIDs which have arc elements
   with values that are less than 2^28, that is, they MUST be between 0
   and 268,435,455, inclusive.  This allows each arc element to be
   represented within a single 32 bit word.  Implementations MUST also
   support OIDs where the length of the dotted decimal (see [RFC 2252],
   section 4.1) string representation can be up to 100 bytes
   (inclusive).  Implementations MUST be able to handle OIDs with up to
   20 elements (inclusive).  CAs SHOULD NOT issue certificates which
   contain OIDs that exceed these requirements.  Likewise, CRL issuers
   SHOULD NOT issue CRLs which contain OIDs that exceed these
   requirements.

   Implementors are warned that the X.500 standards community has
   developed a series of extensibility rules.  These rules determine
   when an ASN.1 definition can be changed without assigning a new
   object identifier (OID).  For example, at least two extension
   definitions included in RFC 2459 [RFC 2459], the predecessor to this
   profile document, have different ASN.1 definitions in this
   specification, but the same OID is used.  If unknown elements appear
   within an extension, and the extension is not marked critical, those
   unknown elements ought to be ignored, as follows:

      (a)  ignore all unknown bit name assignments within a bit string;

Top      Up      ToC       Page 115 
      (b)  ignore all unknown named numbers in an ENUMERATED type or
      INTEGER type that is being used in the enumerated style, provided
      the number occurs as an optional element of a SET or SEQUENCE; and

      (c)  ignore all unknown elements in SETs, at the end of SEQUENCEs,
      or in CHOICEs where the CHOICE is itself an optional element of a
      SET or SEQUENCE.

   If an extension containing unexpected values is marked critical, the
   implementation MUST reject the certificate or CRL containing the
   unrecognized extension.

Appendix C.  Examples

   This section contains four examples: three certificates and a CRL.
   The first two certificates and the CRL comprise a minimal
   certification path.

   Section C.1 contains an annotated hex dump of a "self-signed"
   certificate issued by a CA whose distinguished name is
   cn=us,o=gov,ou=nist.  The certificate contains a DSA public key with
   parameters, and is signed by the corresponding DSA private key.

   Section C.2 contains an annotated hex dump of an end entity
   certificate.  The end entity certificate contains a DSA public key,
   and is signed by the private key corresponding to the "self-signed"
   certificate in section C.1.

   Section C.3 contains a dump of an end entity certificate which
   contains an RSA public key and is signed with RSA and MD5.  This
   certificate is not part of the minimal certification path.

   Section C.4 contains an annotated hex dump of a CRL.  The CRL is
   issued by the CA whose distinguished name is cn=us,o=gov,ou=nist and
   the list of revoked certificates includes the end entity certificate
   presented in C.2.

   The certificates were processed using Peter Gutman's dumpasn1 utility
   to generate the output.  The source for the dumpasn1 utility is
   available at <http://www.cs.auckland.ac.nz/~pgut001/dumpasn1.c>.  The
   binaries for the certificates and CRLs are available at
   <http://csrc.nist.gov/pki/pkixtools>.

C.1  DSA Self-Signed Certificate

   This section contains an annotated hex dump of a 699 byte version 3
   certificate.  The certificate contains the following information:
   (a)  the serial number is 23 (17 hex);

Top      Up      ToC       Page 116 
   (b)  the certificate is signed with DSA and the SHA-1 hash algorithm;
   (c)  the issuer's distinguished name is OU=NIST; O=gov; C=US
   (d)  and the subject's distinguished name is OU=NIST; O=gov; C=US
