I try to harden the security of my Aruba 2930F switch by disabling SHA-1 and enabling SHA-256.
SW01(config)# password non-plaintext-sha256
SW01(config)# password manager user-name admin sha256 [PASSWORD-STR]
When I try to logon from the client machine running Linux with OpenSSH legacy SHA-1 deactivated, I get:
$ ssh firstname.lastname@example.org
Unable to negotiate with 10.0.16.1 port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1
I did follow the ArubaOS Hardening Guide here but I may had missed something.
the first command is for store password on the switch..
the hardening guide is for Aruba OS Mobility Controller
I not sure it is is possible to change the cipher for SSH on ArubaOS switch...
HW HPE 2530-48 ver YB.16.10.0010
ArubaOS-Switch Hardening Guide for 16.06.pdf p19 shown I can create a user with sha256switch(config)# password manager user-name localadmin sha256 95d30169a59c418b52013315fc81bc99fdf0a7b03a116f346ab628496f349ed5
but I can't find sha256, only sha1 in my switch

How to enable user sha256It is easy to decrypt sha1
Hi! have you tried to first enable password storage as encrypted using SHA-256 through the command password non-plaintext-sha256 ? Me too haven't found the sha256 option.
There is no "password non-plaintext-sha256" command
