New issue 2885: Document pypy3's use of keyed hash function. https://bitbucket.org/pypy/pypy/issues/2885/document-pypy3s-use-of-keyed-hash-function
Ryan Hileman: The docs claim PyPy ignores hash randomization: http://doc.pypy.org/en/latest/cpython_differences.html#miscellaneous > Hash randomization (-R) is ignored in PyPy. In CPython before 3.4 it has > little point. However, after asking on IRC, it appears pypy3 *does* use SipHash by default (presumably with a randomized key), but still ignores the -R flag (which doesn't matter because it's on by default). mjacob from IRC: > we didn't follow CPython in implementing their first (unsuccessful) attempt > to fix the problem > however we followed CPython in implementing the second attempt to fix the > problem with a cryptographic hash function > (see also sys.hash_info) I think the cpython_differences doc should be updated to say this is not an issue in pypy3 (if this information is correct). _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
