Syntax

Delphi

Function TPDFlib.GetCertificateIssuerURLs(Const CertDER: AnsiString): WideString;

Parameters

CertDER	The certificate, DER encoded.

Return values

Addresses	One per line.
Empty string	The certificate names none, or it could not be read.

Remarks

The addresses come from the Authority Information Access extension, access method id-ad-caIssuers (RFC 5280 §4.2.2.1).
