--------------------------------------

Hi [~bosco]

# no, user passwors are *not* affected by this code change, only service user's passwords.
AFAIK regular, non-service user passwords are only hashed by org.apache.ranger.biz.UserMgr.encrypt(String,
String)
# un-affected
# Other places this decryption is taking place (besides the already mentioned service create
and service update) are:
* various places at ranger plugins: 
** org.apache.ranger.plugin.client.BaseClient.login() to obtain loginSubject if kerberos is
used
** to programmatically log in using HTTPBasicAuth from ranger plugins (eg.: AtlasClient#getStatusResponse,
KnoxClient#getTopologyList, ServiceSolarClient#getCollection|Cores|FieldsList) to GET|POST
plugin specific data from the given component's rest api

for a complete list of affected places, see usage of method org.apache.ranger.plugin.util.PasswordUtils.decryptPassword(String)

Best regards,
Endre
