EXAMPLE

    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 avoid password prompt or password in command parameter, pg_md5 can read user name:password pairs from file. It will add all user names and md5 hashed password to pool_passwd authentication file.

     $ cat users.txt


     username1:secretpassword1


     username2:secretpassword1


     $ pg_md5 -m -f /path/to/pgpool.conf -i users.txt


     trying to read username:password pairs from file users.txt


     $ cat /path/to/pool_passwd


     username1:md533314126ba0b187df1e37f5ce6a489a8


     username2:md58ae92c6e1d6a48d80e2583fe715e2b36


    

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


      4d45974e13472b5a0be3533de4666414


     

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