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.
Enjoy! Please send me any feedback.
