ASN.1

[6] ASN.1 は、データ構造の記述に関する仕様です。多くの ISO/IEC や ITU の国際規格で採用されています。

符号化規則

[7] ASN.1 は抽象構文なので、実際のファイルやネットワークのデータとしては何らかの具体的な符号化方式により表現する必要があります。次の方式が規定されています。

[19] ASN.1 の符号化規則

データ型

[21] ASN.1 のデータ形式

ASN.1の日時形式

応用

[8] ASN.1 は次の場面で使われています。

The ISO/IEC and ITU-T documents use
the 1997 version of ASN.1; while this document uses the 1988 ASN.1
syntax, the encoded certificate and standard extensions are
equivalent.

This appendix 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".

These definitions use the same "ASN.1-like" syntax defined by RFC 5280.

[16] JISC の対応国際規格検索で ISO 3166 を調べるとなぜか JISX5007 (開放型システム間相互接続−オブジェクト識別子の構成) が出てくる。

[17] >>16 JIS X 5007‐1990 は ISO 8824 の MOD 規格で、 ISO 3166 (JISX0304) は単に引用しているだけらしい。 (JISC の検索で出てくるのはへんだけど。。。)
