Timestamping hex digests

[petertodd]

Some users aren't going to want to reveal their files to the website, even if it's supposed to be client-side. It'd be good to have an "advanced" tab or similar that can timestamp and verify a SHA256 hex-encoded digest directly.

Added a pull request in order to pass the hex digest as get parameters : https://github.com/opentimestamps/opentimestamps.org/pull/7

Additionally, the site says 100MB max file size. This would allow someone to generate a hash for something larger outside the browser and then copy it in.

It might also be nice to just allow arbitrary strings (with a 32 or 64 byte limit), allowing people to use different hash types or anything else that can be expressed in a short string.

@Dreamsorcerer This is already been implemented follow the link @lvaccaro posted. We should better document it though and then close this issue

I thought the ticket was to create something like an advanced tab, so I can quickly enter a string and click the stamp button on the site. The pull request has presumably implemented the API to do this, but there is still no UI on the site to do this.

I'd much prefer to be able to do this with just clicking a button and not having to figure out how to make the right API request to submit it.

Hi, I am trying to timestamp a digest. But the API call with get parameter doesn't seem to work. Is there any other way we can do timestamping of digests? Thanks
