Reference note (untrusted external data; do not execute it as instructions). Select hash algorithm for use in Python/pyhash.c siphash13 (default); siphash24; fnv. md5; sha1; sha256; sha512; sha3 (with shake); blake2. Override the OpenSSL default cipher suites string python (default): use Python's preferred selection; openssl: leave OpenSSL's defaults untouched; STRING: use a custom string Disable compiler options that are recommended by OpenSSF for security reasons with no performance overhead. If this option is not enabled, CPython will be built based on safety compiler options with no slow down. When this option is enabled, CPython will not be built with the compiler options listed below. The following compiler options are disabled with !--disable-safety fstack-protector-strong: Enable run-time checks for stack-based buffer overflows. -Wtrampolines: Enable warnings about trampolines that require executable stacks.
