check for users blank passwords

Hello,

I have an AIX 5.3 system. I want to check users to see whether there are users with blank passwords but i would prefer to do that without checking /etc/passwd or /etc/security/passwd files.
Also while i was searching the web for a solution i noticed that many people refer to /etc/shadow file. The weird thing is that i cannot find this file in my system. It seems that it doesnt exist.
Is there another possible way to do that without needing to read from passwd files?

Thank you for your attention

NAME
pwconv - convert to shadow account SYNOPSIS
pwconv [-P path] DESCRIPTION
pwconv installs and updates /etc/shadow with information from /etc/passwd. It relies on the special password 'x' in the password field of the account. This value indicates that the password for the user is already in /etc/shadow and should not be modified. If /etc/shadow does not exist, pwconv creates this file, moves the user password to it and creates default aging informations with the help of the values of PASS_MIN_DAYS, PASS_MAX_DAYS and PASS_WARN_AGE from /etc/login.defs. The password field in /etc/passwd is replaced with the special character 'x'. If the /etc/shadow does exist, entries that are in the /etc/passwd file and not in the /etc/shadow file are added to the /etc/shadow file. Accounts, which only exist in /etc/passwd, are added to /etc/shadow. Entries that are in /etc/shadow and not in /etc/passwd are removed from /etc/shadow. All passwords from /etc/passwd are moved to /etc/shadow and replaced with the special character 'x'. pwconv can be used for initial conversion and for updates later. OPTIONS
-P, --path path The passwd and shadow files are located below the specified directory path. pwconv will use this files, not /etc/passwd and /etc/shadow. FILES
passwd - user account information shadow - shadow user account information SEE ALSO
