gshadow − shadowed group file
/etc/gshadow contains the shadowed information for group accounts. It contains lines with the following colon−separated fields:
• group name
• encrypted password
• comma−separated list of group administrators
• comma−separated list of group members
The group name and password fields must be filled. The encrypted password consists of characters from the 64−character alphabet a thru z, A thru Z, 0 thru 9, \. and /. Refer to crypt(3) for details on how this string is interpreted. If the password field contains some string that is not valid result of crypt(3), for instance ! or *, the user will not be able to use a unix password to log in, subject to pam(7).
This information supersedes any password present in /etc/group.
This file must not be readable by regular users if password security is to be maintained.
/etc/group

/etc/gshadow
