Convert BER encoded RSA private key to XML (String class)

[Introduced in Sirius Mods 8.0]

RSAPrivateKeyToXmlDoc converts a string (Longstring) that contains an RSA-generated private key to an XmlDoc. DER (Distinguished Encoding Rules), a subset of BER (Basic Encoding Rules, provide a way to uniquely encode an Abstract Syntax Notation One (ASN.1) type value as a string of eight-bit octets.

Syntax

%doc = string:RSAPrivateKeyToXmlDoc Throws InvalidBerData

Syntax terms

%doc An XmlDoc object variable to contain the decoded value of the method object, string.
string A DER encoded string that contains the contents of a digital certificate.

Usage notes

  • Prior to version 7.7 of Model 204, input to this method that created any element in the result XmlDoc with a text child whose length exceeded 650 characters produced an error. An example of such input is a 4096-bit key (which requires 1024 hex characters). As of version 7.7, the lengths of created text nodes are not restricted.
  • RSAPrivateKeyToXmlDoc is very similar to DerToXmlDoc, except that RSAPrivateKeyToXmlDoc understands the semantics of the private key tags, so it provides more meaningful XML element names.
  • RSAPrivateKeyToXmlDoc is a complete implementation of the PKCS standards for private key syntax.
  • Currently, no method is available to produce a DER stream from an XmlDoc nor to validate the signature on a certificate.

Examples

In the following example, the PemToString method loads Longstring %ls with the contents of an RSA private key. RSAPrivateKeyToXmlDoc then converts the Longstring to an XmlDoc whose contents are printed:

... text to %sl = new raw -----BEGIN RSA PRIVATE KEY----- MIIEogIBAAKCAQEAm6TwmSXt4+lyrhwy9SBq2LVjdTeJ5kUbU9jzmBCfw/NuC1tX YAAdc0UG5DDJYPHkWkYa7+z50SYzmoxKI8PfCLyxSOPeVW9CEhRSyiIIlyjQikIK a0YMeOXVetGiutl/y346yQYltkbQXb1SOogTg07fTRs7NWcQ4Rrcd6DEnSkrHxbv T04Z0MwoSojA+NRyBCMpa+w+R0dzrBNZIT11WOccecYjEyuPSS2ydcdgr/Rp4WKC UHmRulXWQjhEjwqFPRG4f8BkYJGr8lN262M4ti4Z11KV/lYA/lEpYUkmCaY936p4 IoVoQy8GFn7mj50sxwSa446bTvKlVPsySMDK2wIBAwKCAQAZ8NLEMPz7UZMdBLMo ... aQmxZUwUo7em8Ci6dX17AoGAcmpQ5AUj5vMdRnOmiIhLM+jgbbQjBD+52hwbkkIn sZ00cQ5asvdrHt3ziIqN7RMu5okuwdFTdk5IGHTA43qykel0e7wxwADI7qybJXWF rsIve5XyKCD55gAM4W8y4+CLkCv6dPwmkTq4vfdaYr0/NPIvigzUq0NEXFVPJfQc GncCgYEAlFIEKq0mVWLBtZRwNjehKOaWGkVVHJnoWqlBngfamQkOiGvWScQ0MVbw K3U00KpuNHRF5RVy035uoU2tnQDLyG+RmUO7j2+t90MOmgXqiZlTz08uf/fQaprd NzpmjANA/9cT3rwHD31LsjaDXASM5IW0q7h+vhvVLtVkDzDnW5w= -----END RSA PRIVATE KEY----- end text %ls = %sl:pemToString('RSA PRIVATE KEY') %ls:RSAPrivateKeyToXmlDoc:print ...
