[jira] [Created] (COUCHDB-2495) Switch PBKDF2 to SHA256

Jan Lehnardt created COUCHDB-2495:
-------------------------------------

             Summary: Switch PBKDF2 to SHA256
                 Key: COUCHDB-2495
                 URL: https://issues.apache.org/jira/browse/COUCHDB-2495
             Project: CouchDB
          Issue Type: Improvement
      Security Level: public (Regular issues)
          Components: Database Core
            Reporter: Jan Lehnardt


We currently use SHA1 for PBKDF2 hashing. While the way SHA1 is used, this doesn’t pose a security issue, it is generally advisable to use a newer hash function, e.g. SHA256. [~kxepal] noted on the user@ list, that this would leave older Erlang versions (R14 and R15) behind, so we can’t do it right now, but we should think about it for the future.
