Upgrade 
from old version 
to new version

On user login:
•

All new-user passwords are hashed and 
saved using SHA-256.

Existing user passwords remain saved using 
the SHA-1 signature, however:


On first login after the upgrade the SHA-1 
hashed password is automatically replaced 
with SHA-256 hashed password.

Note: After an upgrade to version 8.1.4.J there 
will be still passwords saved with the SHA-1 
signature.
In order not to rely on automatic password 
signature conversion and replacement, and to 
ensure that the system only has SHA-256 hashed 
passwords saved, the administrator should:
Either:
•

Ensure that all the users login to the system at 
least once to ensure automatic replacement of 
SHA-1 hashed passwords with SHA-256 
hashed passwords.

Or:
•

Delete and recreate all users.

The new version accepts certificates 
issued with SHA-1 hashing.

hashing:

warning message TLS certificate
