Request for Unix SM3 Algorithm Support

[zhouhaocheng]

Currently, some Chinese operating systems are gradually adopting the SM3 algorithm for system user encryption. The encrypted shadow value is provided below:

testuser:$sm3$wnY86eyUlB5946gU$99LlMr0ddeZNDqnB2KRxn9f30SFCCvMv1WN1cFdsKJ2:19219:0:90:7:35::

The system-auth configuration is as follows:

$ cat /etc/pam.d/system-auth
......
password sufficient pam_unix.so sm3 shadow nullok try_first_pass use_authtok
......

This configuration allows the use of the SM3 algorithm with the shadow file for system user password encryption.
