./toolchain.py build pycrypto doesnt work #384

After building python3, openssl and kivy, I want to build pycrypto by typing: ./toolchain.py build pycrypto It spits out the following error:

It looks like the where the pycrypto tar file was being hosted is no longer available. The URL where the file was hosted previously looks dead(?). This is an interesting recipe because it tries to get the tar file from https://ftp.dlitz.net rather than the pypi website like most of the other recipes. A work around is to change the URL manually to where the file is hosted on pypi.

QUICK FIX: Try changing "https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-{version}.tar.gz" to "https://files.pythonhosted.org/packages/60/db/645aa9af249f059cc3a368b118de33889219e0362141e75d4eaf6f80f163/pycrypto-2.6.1.tar.gz" in line 11 of the init.py file of the pycrypto recipe. The init.py file for the pycrypto recipe can be found in /foo/bar/kivy-ios/recipes/pycrypto folder.

SOLUTION IN THE FUTURE: Update the recipe in kivy-ios for pycrypto to grab the proper URL from the get go.

I think pycrypto should be removed. It is deprecated, contains security issues. It must be replaced with pycryptodome.

Thanks guys. I can now install pycrypto but it is still not working correctly. I have a very simple app: from firebase import firebase I run the following command lines:

./toolchain.py build python3 openssl kivy
./toolchain.py build python3 pycrypto
./toolchain.py create kindact ~/Desktop/main
./toolchain.py pip3 install firebase
./toolchain.py pip3 install pycryptodome
./toolchain.py pip3 install python_jwt

When I click the 'Play' button in Xcode, I get the following errors. I assume it has to do with pycrypto. How do I go about this issue?

Closing issue since Firebase module can be replaced by Requests and json as a workaround.
