SHA1_init missing when using PyInstaller on OSX

[lordi]

When running the executable generated by PyInstaller, I get the following error message. This only happens on OSX, is it possible that a certain dynamically linked library is not picked up?

(..)
  File "Cryptodome/Cipher/PKCS1_OAEP.py", line 175, in decrypt

I'm getting the same error on OS X Catalina with pycryptodomeex (3.9.0), is any progress made (I cannot find the pyinstaller-bump branch?)

The same here with SHA256_init

[sc0ty]

Have the same issue. I can find the symbol _SHA256_init (with underscore) in Crypto/Hash/_SHA256.cpython-37m-darwin.so

nm -C _SHA256.cpython-37m-darwin.so
0000000000002dc0 s _H
0000000000002810 T _SHA256_copy
0000000000000750 T _SHA256_destroy
00000000000025e0 T _SHA256_digest
00000000000006e0 T _SHA256_init
0000000000002840 T _SHA256_pbkdf2_hmac_assist
0000000000000760 T _SHA256_update
...

On my linux box I have there names without underscore:

nm -C _SHA256.cpython-38-x86_64-linux-gnu.so
0000000000002bb0 T SHA256_copy
00000000000029a0 T SHA256_destroy
0000000000002ae0 T SHA256_digest
0000000000002910 T SHA256_init
0000000000002c50 T SHA256_pbkdf2_hmac_assist
00000000000029b0 T SHA256_update
...

I don't have a mac to investigate the issue in detail right now.

I understand that - unlike in Linux - the compiler on OSX will prepend an underscore to all C symbols: the _SHA256_init symbol appearing in the .so file should not be the real issue.

On the other hand, ctypes is supposed to do the right thing and prepend an underscore to all C symbols it is asked to load, if the underlying platform requires so. It seems that ctypes shipped with pyinstaller is not doing that on OSX.

is there a workaround to this issue?

Have you tried hook-Crypto.py?
https://raw.githubusercontent.com/pyinstaller/pyinstaller/develop/PyInstaller/hooks/hook-Crypto.py

https://pyinstaller.readthedocs.io/en/stable/hooks.html

[cbasnett]

Re-igniting an old issue. The above hook did not work in my situation, switching to pycryptodomex rather than pycryptodome does seem to resolve the issue for me. I'm unsure why and I find myself caring less than I probably should..

Then changing imports from:

from Crypto.x to from Pycrypto.x

May be a fluke but works in my situation.

I am having no issues using pycryptodome or pycryptodomex 3.9.7 on my spouse's Mac which is running High Sierra. Cannot test on Catalina because Apple won't allow her 10-year-old Mac to upgrade. Thank you, Apple!

This issue sounds like something to be taken up with pyinstaller.

[mrguodong]

In my case, I used python 3.8 and got below error after running pyinstaller created MACOS application.

AttributeError: dlsym(0x7fb38d73d410, SHA1_init): symbol not found

Created new conda env with python 3.7. This issue did not occur.

The issue here is that .so loading code (both ctypes/cffi) is finding hashlib's .so first which obviously does not have _SHA1_Init & co exports.
The _sha1.cpython-38-darwin.so file is in the Pyinstaller's root directory and the /Cryptodome/Hash/_sha1.cpython-38-darwin.so is not loaded at all. Same stands for other hashing algorithms

same issue after running Pyinstaller with pycryptodome-3.10.1.
I'm in darwin.aarch64.0 (Apple M1), with python 3.8.2 and I can't downgrade because python is not at all compatible with M1.

[Yomguithereal]

Hello everyone, I have the same issue with the SHA1_init symbol on this project built using pyinstaller. I am using python 3.6.10 on a macOS Catalina.

Here is the full trace bubbling from browser-cookie3 to pbkdf2 to finally pycryptodome:

Tell me if I can help in any way and have a good evening (or night, or day, pick your favorite one :) ).

[eric-burel]

Hi guys, do you have any quickfix for this issue? It seems to be fixed in pyinstaller future version (pyinstaller/pyinstaller#5583) but not yet available.
