View the contents of ASN encoded data


This tool is a JavaScript ASN.1 parser that can decode any DigiStamp timestamp that is in the form of a .p7s file. The timestamping WebApp delivers timestamps in this format automatically.

On the left of the page will be printed a tree representing the hierarchical structure.

Hovering on the tree highlights ancestry (the hovered node and all its ancestors get colored) and the position of the hovered node gets highlighted in the hex dump (hex dump is not currently working here).

Clicking a node in the tree will hide its sub-nodes (collapsed nodes can be noticed because they will become italic).

DigiStamp did not write this tool.

This tool would allow you to view a DigiStamp timestamp that you have in the form of a .p7s file; however this tool requires HTML5's File API to function. Please try using the tool in a different browser such as Google Chrome or Mozilla Firefox.
