It's been established that PyCrypto is not maintained. So far, nobody has stepped up to maintain PyCrypto.

It is susceptible to three CVEs, but it is quite possibly vulnerable to more.


It is dangerous to continue using this package, and most people using it are doing so without understanding what they are doing. There are better choices (pycryptodome) and people should be moving to that.

With that in mind, I would like to adopt it in pypi with the goal of having a managed EOL. It would involve a gradually increasing warnings in documentation and installation. I will not maintain the code itself.

It's easiest if the maintainer transfers ownership to me. If not, I'll go through the abandoned projects process:

I've emailed dlitz on Jan 1, 2020 with no response. I'll do that a few more times before proceeding. I expect he's gotten quite a bit of email on this topic over the years.

I'm interested in people's feedback on this.

That sounds like a good plan. Thank you for doing this.

Well ... as long as there is alternatives or github security alerts provides meaningful instructions for replacement, I am also voting for EoL status.

Installing pycrypto should eventually fail and provide information about alternatives like pycryptodome and cryptography.

Thanks for working on this!

amazing idea and a must at this point, as long as pycryptodome will be stable/secure for good amount of time.
nice move @alexdevsec

pycrypto has been unmaintained and already has several CVE's attached to it.

see: pycrypto/pycrypto#301

Proposed alternative is the better-maintained pycryptodome

Will pycrypto be maintained no longer? Now,it is pycryptodome instead?

Hello @alexdevsec ,

I like your initiative; what's the status? I think "nothing happened" for long enough for you to file that pypi abandonment ticket :)

Hello @alexdevsec, thank you for taking the initiative. May I know what is it's current status?

Also, if anyone has used cryptography, does it provide a complete replacement for pycrypto?
