Description
I've made a patch for this here
https://github.com/django/django/pull/12553
Which changes the default salt size from ~71 bits to ~131 bits
The rational is that modern guidance suggests a 128 bit minimum on salt sizes
OWASP: https://github.com/OWASP/CheatSheetSeries/blob/master/cheatsheets/Password_Storage_Cheat_Sheet.md#salting
NIST: https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-132.pdf
In the case of NIST this is technically a hard requirement.
