Name

pg_md5 -- produces encrypted password in md5

Synopsis

pg_md5 [ option ...] -p

pg_md5 [ option ...] password

Description

pg_md5 produces encrypted password in md5.

Options

-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.
-i input_file --input-file= input_file: Specifies file containing user name and password pairs.

Example

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

    $ pg_md5 -p
    password: [your password]

   $ pg_md5 [your password]
   acbd18db4cc2f85cedef654fccc4a4d8

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".
