+Summary: ASN.1 doesn't support undefined length encoding
+
+Description of Problem:
+
+The current ASN.1 class doesn't decode properly objects encoding with
+undefined length encoding (length == 0x80). This was a known issue and is
+not a problem for most structures (like X.509 certificates used in Mono). 
+
+However I just found out that the SPC files provided by VeriSign are
+(a) not binary - they are Unicode
+(b) contains the ASN.1 data in base64
+(c) Use undefined length encoding :(
+
+(a) and (b) aren't much a problem.
+
+
+Current workaround (for Windows users)
+1. Import the SPC file (double-click) in the certificate manager;
+2. Export the new certificate(s) in .DER format;
+3. Execute CER2SPC (Mono or MS version) to construct a SPC file encoded
+"properly" ;-)
