Make password hashing algorithm/cost configurable for the
stored passwords of users for the realms that this applies
(native, reserved). Replaces predefined choice of bcrypt with
cost factor 10.
This also introduces PBKDF2 with configurable cost
(number of iterations) as an algorithm option for password hashing
both for storing passwords and for the user cache.
Password hash validation algorithm selection takes into
consideration the stored hash prefix and only a specific number
of algorithnm and cost factor options for brypt and pbkdf2 are
whitelisted and can be selected in the relevant setting.
Limits the scope of the runtime dependency on
BouncyCastle so that it can be eventually removed.
* Splits functionality related to reading and generating certificates
and keys in two utility classes so that reading certificates and
keys doesn't require BouncyCastle.
* Implements a class for parsing PEM Encoded key material (which also
adds support for reading PKCS8 encoded encrypted private keys).
* Removes BouncyCastle dependency for all of our test suites(except
for the tests that explicitly test certificate generation) by using
pre-generated keys/certificates/keystores.
The elasticsearch-users utility had various messages that were
outdated or incorrect. This commit updates the output from this
command to reflect current terminology and configuration.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
