[issue13703] Hash collision security issue

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

I read that the attack cannot be computed with actual computers (it's too expensive) against Python 64 bits. I tried to change str.__hash__ in Python 32 bits to compute the hash in 64 bits and than truncate the hash to 32 bits: it doesn't change anything, the hash values are the same, so it doesn't improve the security.
