I want to compile an exe with encryption (to prevent "casual" decompiling).
I am able to compile with Pyinstaller v2.1 in one exe file using a spec file, when I don't use encryption.
But, when I add the following line to the .spec file to introduce encryption (pycryptodome ):
block_cipher = pyi_crypto.PyiBlockCipher(key='1234567812345678')
I end up with this error:
File "c:\users\username\test-env\lib\site-packages\Crypto\Util\_raw_api.py", line 151, in c_uint8_ptr
raise TypeError("Object type %s cannot be passed to C code" % type(data))
TypeError: Object type <class 'str'> cannot be passed to C code
The log leading up to the error was:

Seems like it is a problem with the "key" which is class 'str'. I tried to change in the .spec file the key = 'a123456712345678' or u'1234567812345678' but still have the problem.
