Peppering passwords has been a controversial topic widely discussed in
many stack overflow questions. Having ran my 20+ personal email addresses
through HIBP page the findings are clear: all emails/passwords of mine
that had been leaked fall in the following categories: SQL injections,
mis-configured databases, exposed database admin panels or strayed
database backup files.
And that’s exactly what a pepper value in the hashing process is
protecting from. Breaching the whole server with physical access to the
file system is rather rare nowadays.
According to this NIST document [ Digital Identity Guidelines
Authentication and Lifecycle Management]
https://pages.nist.gov/800-63-3/sp800-63b.html :
“In addition, verifiers SHOULD perform an additional iteration of a key
derivation function using a salt value that is secret and known only to
the verifier.”
So, why not in Django?
