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

  1. 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.

  2. In the RSAPrivateKeyToXmlDoc example, the PemToString method loads a Longstring with the contents of an RSA private key. If that Longstring is also %ls below, the following statement converts that string to the XmlDoc whose contents are printed below. Compare the XML tags in these results with the tags produced by RSAPrivateKeyToXmlDoc:

    %ls:derToXmlDoc:print

    The result is shown in part below:

    <Sequence> <Integer>0</Integer> <Integer>196482721346 ... ...685825059547</Integer> <Integer>3</Integer> <Integer>327471202244 ... ...832238758867</Integer> <Integer>163032211406 ... ...063864355897</Integer> <Integer>120517730607 ... ...628528150451</Integer> <Integer>108688140937 ... ...709242903931</Integer> <Integer>803451537383 ... ...419018766967</Integer> <Integer>104154110092 ... ...977615354780</Integer> </Sequence>
