Hi all!
I would like to mention ASN.1 Editor
<http://lipingshare.com/Asn1Editor/> (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
