Convert CRL PEM to XML

See more PEM Examples

Loads a CRL (Certificate Revocation List) from the PEM file format and converts to XML to allow for visual examination and parsing.

Note: This example requires Chilkat v9.5.0.77 or greater.

Ruby

require 'chilkat'

success = false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example requires Chilkat v9.5.0.77 or greater.
pem = Chilkat::CkPem.new()

if (success != true)
    print pem.lastErrorText() + "\n";
    exit
end

numCrls = pem.get_NumCrls()
i = 0

asn = Chilkat::CkAsn.new()
xml = Chilkat::CkXml.new()
while i < numCrls

    # Get the CRL as base64 (multi-line)
    crlBase64 = pem.getEncodedItem("crl","","base64_mime",i)
    if (pem.get_LastMethodSuccess() != true)
        print pem.lastErrorText() + "\n";

    if (success != true)
        print asn.lastErrorText() + "\n";
        exit
    end

    # Convert ASN.1 to XML and load into xml and re-emit for pretty printing..
    xml.LoadXml(asn.asnToXml())
