Re: Web-based ASN.1 decoding tool available

Hi all!
I would like to mention ASN.1
Editor (for Windows) which is not a web-based tool and although it
can't provide default values from DER,
it lets you:
- inspect ASN.1 structures and encapsulate parts of the structures
in a more user-friendly way than simple dump tools;
- edit ASN.1 structures;
- save sub-parts/structures to a new file;
- etc.
It also includes a simple but nice data converter between PEM, HEX and
BASE64 formats.
Best regards,
Ricardo Barroso

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.

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.
