DerToXmlDoc (String function)
Convert DER encoded data to XML (String class)
[Introduced in Sirius Mods 8.0]
DER (Distinguished Encoding Rules) provide a way to uniquely encode an ASN.1 type value as a string of eight-bit octets.
DerToXmlDoc converts such a string to an XmlDoc.
Syntax
%doc = string:DerToXmlDoc Throws InvalidBerData
Syntax terms
| %doc | An XmlDoc object variable to contain the decoded value of the method object, string. |
|---|---|
| string | A DER encoded string. |
Usage notes
- Currently, no method is available to produce a DER stream from an XmlDoc.
Examples
The PemToString example loads a Longstring with the contents of the base64 encoded CRL (Certificate Revocation List). If that Longstring is %ls below, the following statement converts that string to the XmlDoc whose contents are printed thereafter:
%ls:derToXmlDoc:print
The result is shown in part below:
<Sequence> <Sequence> <Sequence> <ObjectIdentifier>1.2.840.113549.1.1.4</ObjectIdentifier> <Null/> </Sequence> <Sequence> ... <Set> <Sequence> <ObjectIdentifier>2.5.4.8</ObjectIdentifier> <PrintableString>QLD</PrintableString> </Sequence> </Set> ... <UTCTime>20010115162657.000Z</UTCTime> <UTCTime>20010214162657.000Z</UTCTime> <Sequence> <Sequence> <Integer>1</Integer> <UTCTime>19951009233205.000Z</UTCTime> </Sequence> <Sequence> <Integer>3</Integer> <UTCTime>19951201010000.000Z</UTCTime> </Sequence> ...
The ellipses indicate snipped content and are not part of the XmlDoc.
