Proposal: HTTP(S) Download Test

Both Gettor and Tor's main website are targets that attract censorship agencies and law enforcement. We should have an automatic way of testing if an HTTP(s) URL is accessible. Given a URL, the probe will download a maximum of maxFetchSize bytes of data, calculate its digest, and return the digest if it exists, time in second to complete the download attempt and error if it exists.

Input

To test an HTTP(S) URL's reachability, send a POST request to

https://HOST/http-state

with a request body of

{
    "url":"http://domain.name/path",
    "maxFetchSize":102400
}

Output

{
    "error":"error reason",
    "sha256":"base64Ofhash",
    "downloadSize":102400,
    "time":0.123
}
