psql and md5

[John DeSoi]

Is there a way to provide a md5 password directly to psql? I'm aware of
pgpass but I would like to store a md5 password in some other location
and then use it to execute commands with psql.

Thanks,

Hi

You can always generate the md5 password using perl/php and store the password
in database. I believe the next version of pgsql will have an internal md5
function.

I guess :

Bienvenue dans psql 7.4.2, l'interface interactive de PostgreSQL.

select md5('abcdef');
md5

psql is a client application. It supports md5 as an authentication
method to the server, but the password provided to psql must be plain
text as far as I can tell. My goal here is to store some psql
connection information in something like the pgpass file, but I don't
want to leave passwords without some kind of protection.

Hi,

this would not be very useful. The database you are talking to needs to know
if you know the password and not only the md5-password. If you only need to
tell psql the md5-password, you don't need to know the real one.

Yes, you are right. I did not think the issues through clearly enough
before posting my question.

I have resolved things by using reversible encryption to store the
passwords (blowfish).
