Short Description

The aliyunsdkcore package depends on pycrypto>=2.6.1, which is deprecated, unmaintained, and fails to build on Python 3.13+ due to missing internal Python headers (longintrepr.h).

Impact:

• Breaks installations on modern Python versions (3.13+).
• Security risk due to unpatched vulnerabilities in pycrypto.

Suggested Fix:
Replace pycrypto with the maintained fork pycryptodome (API-compatible drop-in replacement).

Reproduction Steps:

1. Install aliyunsdkcore on Python 3.13.
2. Observe build failure due to pycrypto dependency.

Workaround:
Manually install pycryptodome and remove pycrypto, but this should be fixed upstream.

Additional Notes for the Report

• Link to pycrypto deprecation: PyPI
• pycryptodome is the recommended alternative (used by paramiko, google-auth, etc.).
• Example error:

  src/_fastmath.c:33:10: fatal error: longintrepr.h: No such file or directory
  

This change would improve compatibility and security. Thanks for maintaining the SDK!
