pg_md5 - produces encrypted password in md5

pg_md5 [option...] -p

pg_md5 [option...] password

pg_md5 produces encrypted password in md5.

-p
--prompt

Prompt password using standard input.

-m
--md5auth

Produce md5 authentication password to authentication file pool_passwd.

-u your_username
--username=your_username

When producing a md5 authentication password, create the pool_passwd entry for your_username.

-f config_file
--config-file=config_file

Specify the path to the pgpool.conf configuration file.

The following are examples to encrypt your password into md5 hash format for pcp.conf.



    $ pg_md5 -p


    password: [your password]

or



   $ pg_md5 [your password]

pg_md5 can also be used for adding an entry of user name and md5 encrypted password to pool_passwd authentication file.



     $ pg_md5 -m -f /path/to/pgpool.conf -u username -p


     password: [your password]


     $ cat /path/to/pool_passwd 


     username:md55a231fcdb710d73268c4f44283487ba2

To just display the md5 hashed string, not adding an entry to pool_passwd, pass a string concatenating password and user name. For example, if password is "password" and user name is "user", the output would be:



      $ pg_md5 passworduser

Please note that the actual entry to be inserted into pool_passwd should have "md5" on top of the result string. That is: "md54d45974e13472b5a0be3533de4666414".
