publickey().exportKey(format="OpenSSH") failing on python 3.4 about pycrypto HOT 11 OPEN

Any idea when this will be released?

from pycrypto.

Can we please get a release with this fix?

from pycrypto.

Yes, move your project to pycryptodome. It is a drop-in replacement for pycrypto.

python 2.7.8 works with no problems.

+1. Same issue
Python 3.4.0, pycrypto==2.6

Importing OpenSSH keys is also broken on 2.6.1:

This issue will be fixed ver 2.7.1. see below.

I'm not sure. See this: #173

Hi guys, (cc @dlitz )

I'm landing here after getting the same issue:

  File "/usr/lib/python3.6/site-packages/Crypto/PublicKey/RSA.py", line 352, in exportKey
    keystring = ''.join([ struct.pack(">I",len(kp))+kp for kp in keyparts])
  File "/usr/lib/python3.6/site-packages/Crypto/PublicKey/RSA.py", line 352, in <listcomp>
    keystring = ''.join([ struct.pack(">I",len(kp))+kp for kp in keyparts])
TypeError: can't concat str to bytes

Is it possible, either:

• to ship a new version (2.7 ?) in PyPi, since the actual one 2.6.1 is quite out of date
• to backport this fix ab25c6f
  in PyCrypto 2.6.1 ?
• to mark this lib is as unmaintained?

Thanks a lot for your feedback, let me know if I can help

from pycrypto.

Side question: should I move my project under https://github.com/Legrandin/pycryptodome that looks to be actively maintained?

from pycrypto.

@galgalesh Thank your for advice :) good to know there is a drop-in replacement lib!

In a future step, I will probably move to cryptography since it is already a dependency of a dependency of my project and I don't do very much crypto actually.
