Обсуждение: [GENERAL] create trigger in postgres to check the password strength
Hi All,
Is this possible to create trigger in postgres to check the password strength( like char should be min 8 character) while to creating user or role with password.
If it possible can you please share the script with me..

Whoops, accidentally sent this to only Pawan instead of the list:
Hey there, so I would highly suggest you avoid arbitrary password strength policies like that. I wrote a library for my company which we use for password strength estimation, but it is written in Java. I've been thinking about how to port it to pl/pgsql so it could easily be packaged as an extension and used natively in Postgres, but I just haven't had time to get around to that yet. Here it is for reference: https://github.com/ GoSimpleLLC/nbvcxz
If you're actually interested in having an extension which works like the above, and want to work on porting it, i'd be more than happy to jump in and help out where I can. I just don't have the free cycles to do it my self at the moment.
Now on to your original question...Why wouldn't it be possible to create a trigger on your users table to check the password being inserted, raise an error if it does not meet your requirement, or hash it if it does and continue the insert? Seems pretty straight forward other than the complexity of actually estimating how secure a password is.

Thanks Adam, but here the requirement to enforce password polices while creating to the users.
create user abc with password 'Password';
where it will test that the password entered should be according to the company standard, while creation of users.
So please suggest.

Consider using PAM authentication where you can insert any of already existing password strength checks.
Or, maybe, LDAP auth where stuff will be enforced by LDAP server.

Oh sorry, I misunderstood. Didn't realize you meant database users an not an application user table implemented in Postgres. I'll let others answer that then because i'm not aware of a way to do that.
