+1 to Eric's praise.  Nice idea.

Thanks Richard.  :-)

Even better if you were to open-source the code ;)

That's a conversation I've yet to have with my employer.

David Keeler has done some work on visualizing certs that may be helpful.

I'll take a look.  Thanks.

I notice that % is your wildcard character.  Hopefully this doesn't
indicate a SQL injection risk!

What sort of SQL injection risk are you concerned about?

http://en.wikipedia.org/wiki/SQL_injection
"SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker)"

"to dump the database" is kinda the point of crt.sh.  :-)

All of the data is already public (in the CT logs). I would happily permit searches for "?q=%25" if I had unlimited bandwidth and server performance. (Currently any search that's still running after a minute or two is automatically killed).

Also, the database used by https://crt.sh is a read-only slave, so even if you could inject something like "DROP TABLE certificate", it would fail to execute.

This is outstanding - simple, but totally what people need to start
getting the idea and benefit of CT.

Thanks Eric.  :-)

One high ROI addition might be RSS feeds for search terms. That way, I
could create e.g. an IFTTT alert that emails me whenever a certificate
is publicly logged as being issued for my domains.

Indeed.  It's on the todo list.

    Hi.  I thought folks here might find this useful.  It's a web
    interface that lets you search for certs that have been logged by CT.

    https://crt.sh

    Pronounced "search".  :-)
