Show HN: Online ASN1 DER parser and editor
crypto.qkation.comHello HN,
For the last 3 years, I have been working on a tool to help me debug ASN1-encoded data (keys, certificates, Kerberos/CredSSP/SPNEGO/etc data structures, and more) and cryptographic operations.
A few days ago, I shipped a significant feature: ASN1 tree editor. Now it can parse and edit the ASN1 tree directly on the page. I found it very useful and may be helpful for others.
Follow the link and try it. Short manual:
* hold `ctrl` and click on the tree node title to edit;
* hold `ctrl` and move the mouse between nodes to add a new node;
* hold `ctrl` and move the mouse to the start of the node title to remove the node.
A complete user guide with images can be found in my blog post: https://tbt.qkation.com/posts/announcing-crypto-helper-0-16/.
Overall, this tool can also perform many crypto-algorithms and has a JWT debugger. But that's another story :)
