Hi,

please help me the usage of /etc/default/passwd

and i am planning to change the encrypt method from md5 to SHA512
on /etc/detault/passwd file, will that impact my /etc/passwd file.

or i need to do any changes after modifying the /etc/default/passwd.

and is there any way that i can find which encryption method my current users using in /etc/passwd.

Are you maybe on a Solaris system rather than a Linux system? So far as I know there is no /etc/default/passwd in Linux.

You rarely, if EVER, have come back to post your results or even say thanks over the many years you've been here.

Covered here, since you ask about RHEL often:

And putting "how to find out what is used for linux passwords" into Google pulls up LOTS:

SLES 11 is a commercial, pay-for distro. Paying for it also gets you support from SuSE, so the best thing to do is to call them. Have you? Have you looked IN that file?

This link seems to directly address the original question:

I'm relatively new to SLES, and I've really struggled to get my head
around PAM configuration. Mostly there now, but the biggest hurdle by
far was getting SHA256 hashes on my shadow passwords.

The updated documentation for PAM_UNIX2 points me in the right
direction, but it's not at all clear. Hopefully this will help any
other newcomers with the same issue.

Start with a default config:

*pam-config -c*
then update /etc/default/passwd and change as follows:

CRYPT=SHA256
CRYPT_FILES=SHA256
