Using Hash Passwords for Improved Security

For iDRAC in 13 th generation servers, you can set user passwords and BIOS passwords using a one way hash format. The user authentication mechanism is not affected (except for SNMPv3 and IPMI) and you can provide the password in plain text format.

With the new password hash feature:
  • You can generate your own SHA256 hashes to set iDRAC user passwords and BIOS passwords. This allows you to have the SHA256 values in the server configuration profile, RACADM, and WSMAN. When you provide the SHA256 password values, you cannot authenticate through SNMPv3 and IPMI.
  • You can set up a template server including all the iDRAC user accounts and BIOS passwords using the current plain text mechanism. After the server is set up, you can export the server configuration profile with the password that has hash values. The export includes the hash values required for SNMPv3 and IPMI authentication.

You can generate the hash password with and without Salt using SHA256.

You must have Server Control privileges to include and export hash passwords.

If access to all accounts is lost, use iDRAC Settings Utility or local RACADM and perform reset iDRAC to default task.

If the iDRAC user account’s password is set with the SHA256 password hash only and not the other hashes (SHA1v3Key or MD5v3Key), then authentication through SNMP v3 and IPMI is not available.
