Not sure how to solve this. My code works on various machines but not my AWS Lightsail instance.

I tried running the test. The error:

I see you're probably working on it but filing this for tracking purposes.

After encrypt() when I want to decrypt I get a data is not a valid scrypt-encryption block

With the use of f-strings in setup.py, is this project still considered python 2 compatible?

Building wheels for Python 3.10 on Windows is explicitly disabled. Can this be enabled and wheels be published for Python 3.10 on Windows?

I wrote a test to test a function where I use .decrypt(). In this test I use the same MAXTIME (0.5) in encrypt as in the tested function. Despite that I get sometimes "decrypting file would take too long" error.
I tried also to encyrpt with 0.5 and decrypt with 1. I also sometimes got the error.
With 0.2/0.5 This seems to work. At least until now.
Why can this happen? And what is the best practice for the MAX values?

Problem

On aarch64, pip install py-scrypt builds the wheels from source code and then install it. It requires user to have development environment installed on his system. also, it take some time to build the wheels than downloading and extracting the wheels from pypi.

Resolution

On aarch64, pip install py-scrypt should download the wheels from pypi

@holgern, Please let me know your interest on releasing aarch64 wheels. I can help in this.

It appears there is no wheel for macos on python 3.9 in 0.8.18, only 3.5, 3.6, 3.7 and 3.8.

There are wheels for 3.9 for linux and windows, but not macos.

Feel free to close if this is intentionally unsupported

scrypt-0.8.19.tar.gz does not include scrypt-windows-stubs/gettimeofday.c for some reason, causing the installation to fail on windows.

EDIT: probably because the MANIFEST.in only grabs *.h files from that dir.

Whenever I try install scrypt I get this error:
fatal error: 'openssl/aes.h' file not found #include <openssl/aes.h> ^~~~~~~~~~~~~~~ 1 error generated. error: command '/usr/bin/clang' failed with exit code 1

I have installed Openssl (via brew) & ran the folllowing commands:

$ export CFLAGS="-I$(brew --prefix openssl)/include $CFLAGS" $ export LDFLAGS="-L$(brew --prefix openssl)/lib $LDFLAGS"
