Re: Web-based ASN.1 decoding tool available

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.

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.
