RE: Web-based ASN.1 decoding tool available

Hi all,

This one is also nice... 
And somebody could try to use it in online PHP :-) with at least ASN.1 modules 
which are described in PKIX, SMIME RFCs.

Hi Peter,

        
        Have you any free tools which are not the simple dump of asn1 DER/BER 
but which also can read a data according the 1988, 93 ASN.1 Syntax? 
        Like default values from DER...


I'm afraid I do not and I'm not aware of any such tool. To get the default 
values, you would need the actual ASN.1 (which provides the default values) and 
the BER/DER data.

BERViewer, Peter Hesse's web tool, Peter Gutmann's dumpasn1 and others similar 
tools just decode the BER/DER and present it in a "more" human readable form.

Regards,
Aram

                All,
                


                We have recently made available a web-based tool for doing an 
ASN.1 dump.  It 
                

                displays the ASCII HEX and the ASN structure, and when you 
hover over the 
                

                structure, it highlights the relevant portion of the hex. 
(Clicking makes the 
                

                highlight stick.)
                


                Due to PHP’s inefficiency and memory usage during parsing, we 
have limited it 
                

                to files 64K and smaller.  Still, it is useful for displaying 
smaller objects 
                

                when you don’t have dumpasn1 installed or available.
                


                It can be found here: 
http://geminisecurity.com/features-downloads/tools#fd_5
                

                Click on “Click to try the application” under PHPdumpASN.
                


        For Windows, you can also try BERViewer 
<http://homepage.mac.com/aramperez/berviewer.html> 
<http://homepage.mac.com/aramperez/berviewer.html> . I haven’t had time to 
remove the nag dialog box from the Mac version.
