[jira] [Commented] (COUCHDB-2066) Don't allow stupid storage of passwords

["Jan Lehnardt (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-2066?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13902584#comment-13902584 ] 

Jan Lehnardt commented on COUCHDB-2066:
---------------------------------------

Since 1.3.0, CouchDB uses PBKDF2 for password hashing for user accounts.

CouchDB will accept the old sha+salt format to not break BC, since it was introduced in a minor version update.

Users are discouraged to use the old sha/salt ones though, we just kept the API intact.

What we should do, though, is adding a transparent layer to turn sha+salt-style PWs into pbkdf2 PWs transparently.

I’m not sure how to swing that without a API BC break, and we should run this plan by a proper cryptographer.

> If a password_sha/salt combination is PUT into the _users db, wrap that up in PBKDF2.
