LEI in Digital Certificates Best Practice Definition

Table of Contents

As we work closer with Certificate Authorities (CAs) on building LEI information into Digital Certificates a standard implementation schema is necessary. As of February 2019 the following definitions are considered best practice:

 


LEI
DEFINITIONS IMPLICIT TAGS ::= BEGIN

ub-leiRole-length INTEGER ::= 100

Lei     ::= SEQUENCE {
        leiCode         PrintableString(SIZE(20)),
        leiRole [0]     EXPLICIT PrintableString(SIZE(1..ub-leiRole-length))
                        OPTIONAL
         }

EXTENSION       ::= CLASS {
         &id     OBJECT IDENTIFIER UNIQUE,
         &ExtnType }
WITH SYNTAX {
         SYNTAX  &ExtnType,
         IDENTIFIED BY &id
         }

lei     OBJECT IDENTIFIER ::= {1 3 6 1 4 1 5222266 1}

leiExtension    EXTENSION ::= {
         SYNTAX  Lei,
         IDENTIFIED BY lei
         }

Extension ::= SEQUENCE {
         extnId  EXTENSION.&id({ExtensionSet}),
         critical        BOOLEAN DEFAULT FALSE,
         extnValue       OCTET STRING
         (CONTAINING EXTENSION.&ExtnType({ExtensionSet}{@extnId})
                 ENCODED BY der),
         ...
         }

der     OBJECT IDENTIFIER ::=
    {joint-iso-itu-t asn1(1) ber-derived(2) distinguished-encoding(1)}

ExtensionSet    EXTENSION ::= {leiExtension,...}

END
