Change the password hashing algorithm

Change the password hashing algorithm for user passwords in a Redis Enterprise Software cluster.

Redis Enterprise Software securely stores all user passwords using a cryptographic hash function. The default password hashing algorithm is SHA-256, but PBKDF2 is also supported as of Redis Enterprise Software version 7.8.6-13.

You can change the password hashing algorithm using rladmin or the REST API. When you change the password hashing algorithm, the cluster rehashes the administrator password and passwords for all users, including default users.

Command-line method

To change the password hashing algorithm from the command line, run rladmin cluster change_password_hashing_algorithm:

rladmin cluster change_password_hashing_algorithm PBKDF2

REST API method

You can change the password hashing algorithm using a REST API request:

PATCH /v1/cluster/change_password_hashing_algorithm
{ "algorithm": "PBKDF2" }
