New submission from Christian Heimes: OpenSSL has a function called OPENSSL_ia32cap_loc() to get the processor's capability vector in X86 and X86_64 systems. The information is useful to decide which cipher suite to prefer. For example on machines without AES-NI and CLMUL CPU instructions, ChaCha20 should be prefered over AES-GCM.
https://www.openssl.org/docs/man1.0.2/crypto/OPENSSL_ia32cap_loc.html #27766 just exposes the plain OPENSSL_ia32cap_loc(). A richer API should parse the bit field and expose the bits as structure. ---------- components: Extension Modules messages: 272763 nosy: alex, christian.heimes, dstufft, giampaolo.rodola, janssen priority: normal severity: normal status: open title: ssl: add public API for IA-32 processor capabilities vector type: enhancement versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27768> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
