RoboHash

The source code for RoboHash.org.

It basically copy/pastes various robot pictures together, using bits from the SHA hash. It's not perfect, and not entirely secure, but it gives a good gut-check to "Hey, this SHA is wrong."

Install

Just the library:

$ pip install robohash

Or if you also want the web frontend:

$ pip install robohash[web]

Usage

from robohash import Robohash

hash = "whatever-hash-you-want"
rh = Robohash(hash)
rh.assemble(roboset='any')
with open("path/to/new/file.png", "wb") as f:
    rh.img.save(f, format="png")

Robosets

RoboHash comes with five image sets, named "set1", "set2", "set3", "set4" and "set5". Specify which set you want in the assemble() method. Alternatively, specify the string "any", and RoboHash will pick an image set for you, based on the provided hash.

OK, I'll admit I'm a crappy programmer. Compounding this, I wrote this code initially to be internal-only. It's ugly, and could be a LOT nicer.

Sorry about that.

robohash's Issues

Bump the version

Could you release a new version to PyPI, because v1.0.0 is affected by the sorting issue?

Usage Instructions

I've managed to import the Robohash module just fine by creating an arbitrary file.

Does the script run on the fly or does anything need to be compiled or processed first?

Any assistance much appreciated - great library, I'd like to get better at understanding it's usage and hopefully provide more useful feedback.

Thanks,
Mark

image library for color overlay?

haha awesome. Is it in the roadmap to create all the colors from a template?

Incrementing Bgset stops at 2?

I tried to go past bgset2 and i wasn't able to get any images behind my robots

Link not working: https://robohash.org/3f6e64bb.png?bgset=bg3

BTW absolutely love the library, using it my app :)

robohash.org is returning 525, 520, and 500 errors

I can reproduce this by going directly to robohash.org and clicking generate a few times. Maybe Cloudflare is having issues?

One particular IP address crashes, but only on set5

This is weird:

import robohash
rh = robohash.Robohash("65.255.59.74")
rh.assemble(roboset='set5')

Traceback (most recent call last):
File "", line 1, in
File "robohash/robohash.py", line 183, in assemble
roboimg.paste(img,(0,0),img)
File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 1457, in paste
self.im.paste(im, box, mask.im)
ValueError: bad transparency mask

Change the IP address by one digit, change the set, and it works fine.

pip freeze | grep -i robo
robohash==1.0

Am I doing something wrong? Love this program, and it's so helpful in telling when my IP address has changed...

Windows Git Bash uses cp1257 encoding by default, README contains Unicode emoji that doesn't have a mapping in cp1257, hence the error.

Fix is simple, use

Robohash seems to be down again

Hi @e1ven,

Robohash seems to be down at the moment. Could you take a look?

Robohash.org is down

It seems like a dns problem.

ERR_NAME_NOT_RESOLVED

Site's down :(

Can't access robohash.com, anything we can do to help?

Thanks!

set5 isn't being displayed and slower than the other sets

Through the caching the new set5 isnt displayed on the main page.

Besides that, there seems to be an performance-issue.
Generating a hash with set 4 are at average at 1 second. Generating a image for a hash with set5 need up to 10 seconds. Is there a need to resize the images of set5 to decrease response-time?

best regards

JPEG background black - occasionally

http://robohash.org/dsfaasdf.png comes with a white background and http://robohash.org/dsfaasdf.jpeg with a black one (at least it is displayed as such in Safari)

I assume this is not intentional. See:

Robohash website is down

Robohash server is showing invalid SSL certificate:
https://robohash.org/

SVG support

It would be cool

robohash.org is down

Hi @e1ven,

robohash.org seems down again,

Could you please have a look?

I created a .net copy based on SkiaSharp

Excellent work! ♥♥♥♥♥♥♥
I translated to C# 😄

Images and GPL compatibility

I realize this is not your main concern for this package, but is there a chance to get in touch with the artists and ask them to relicense (or dual-license) the images as CC-BY-4.0 to allow for compatibility with GPL-licensed implementations? I wanted to integrate @nimiq's Robohash SVG into my WordPress plugin Avatar Privacy, but it looks like their SVG parts are derived from Zikri Kader's set1. (They might have relicensed them from Zikri, but going with proven provenance PNG icons seems safer.)

Hashes don't work on all sets

These are all the same:
https://www.robohash.org/a42a477e8cbbe37db52bb7175a911ca1?set=set1
https://www.robohash.org/a42a477e8cbbe37db52bb7175a911ca1?set=set2
https://www.robohash.org/a42a477e8cbbe37db52bb7175a911ca1?set=set3

But cats work :)
https://www.robohash.org/a42a477e8cbbe37db52bb7175a911ca1?set=set4

500 errors continue

Similarly to #51, more 500s:

$ curl https://robohash.org/asdf\?size\=32x32
<html><title>500: Internal Server Error</title><body>500: Internal Server Error</body></html>

10% chance of slow response

I've got a page that downloads 10-ish robohash robots. I'm finding that often 1 of the 10 robots will take about a minute to download while the rest are rather quick. Is this normal?

I think robohash is down. Everything ok?

On Apache Server

Hello,

Anyone have tried to run this on apache based system? With mod_wsgi?

URL's are not responding

The API responds with a URL, but the URL is non-responding. I can see robohash.org has the same issue. Pretty sure it worked yesterday.

Version on PyPI is newer than version on GitHub

Here is the page on PyPI:

https://pypi.org/project/robohash/

As you can see, the current version on PyPI is 1.1, which was released on 1 March 2020.

However, here in GitHub, the version in setup.py is 1.0, and the latest commit is in August 2019.

Here be dragons!

Not an issue but I made it so.

I made this...

http://www.robotrak.tk

Site is down.

Please fix.

Example url: https://robohash.org/49c9cd05f52ef04074114811a5e2d942?set=set4&gravatar=hashed&size=75x75

No module named natsort and some tips

Not very friendly to noob,so add sudo pip intsall natsort or other tips please :)
Not sure how to use it, it is a good project

robohash site is down

Error 526: Invalid SSL certificate
e.g. https://www.robohash.org/5d2ccf2d41720bd083f79db98bb9c585?set=set3

robohash is down ?

the site is not accessible at the moment. everything okay ?

Update cat URL

The old URL for the cat/set4 in README is outdated and doesn't work anymore. The new link is https://www.peppercarrot.com/extras/html/2016_cat-generator/ . Would it be possible to update it?

name ’Robohash‘ is not defined

I tried to run it locally. Following the usage instruction, but failed. It said "name ’Robohash‘ is not defined"

Images does not match for the same hash but different sizes

Hello!

For some reason robohash generates different image for a hash when specifying different sizes.

I've tried different sizes and found, that images does not match for 64x and 63x sizes.

Yellow robot:

• https://robohash.org/fd7a4c9e24ae4ed592abba0098c18859395aba2d?size=63x63
• https://robohash.org/fd7a4c9e24ae4ed592abba0098c18859395aba2d?size=64x64

Purple robot:

• https://robohash.org/fd7a4c9e24ae4ed592abba0098c18859395aba2d?size=16x16
• https://robohash.org/fd7a4c9e24ae4ed592abba0098c18859395aba2d?size=65x65
• https://robohash.org/fd7a4c9e24ae4ed592abba0098c18859395aba2d?size=128x128
• ... and all other sizes I've tried.

Thank you.

HTTPS Certificate expired on robohash.org

Hey,

The SSL certificate expired some hours ago.
Could you please fix it ?

Wrong image set

Using https://robohash.org/kitty?set=set4 I am getting a kitty picture like it should:

But if I provide https://robohash.org/kittytit?set=set4 I am getting a robot:

And if I try something close to it like https://robohash.org/kittyt?set=set4 then I'm getting back a kitty again:

Not sure what went wrong there... 😋

Is Robohash (not the website, but the image generator) down?

Hi @e1ven,

I have noticed that all of the requests I've made since at least about 4 hours ago (could have been going on for longer, and I just didn't realise) have returnedd a 522 connection timed out. Wondering if your server is down?

e.g. https://robohash.org/test123

By the way, great project, I absolutely love the different image sets (especially the cats)!

500 Error when submitting a request

I submit a testing request: https://robohash.org/[email protected]?set=set5&bgset=bg2 and get a 500 error, but if I submit https://robohash.org/max@redbullcom?set=set5&bgset=bg2 (without the dot in the email) it works fine
others work fine: https://robohash.org/[email protected]?set=set5&bgset=bg2
Just wanted you to be aware that's all. :-)

Robohash not generating images

Hi e1ven,

2 days ago the robohash script stopped generating images and gives internal service error.
Its in this example link.
http://bloodbanker.org/robohash/test.png?size=50x50

But it is up and running on the homepage in this link.
http://bloodbanker.org/robohash

What could be the possible problem?
