| = Hash password |
| |
| The `hash_password` tool is used to get the jBcrypt hash of a password. This hash |
| can be used in CREATE/ALTER ROLE/USER statements for improved security. |
| |
| This feature can be useful if we want to make sure no intermediate system, logging or |
| any other possible plain text password leak can happen. |
| |
| == Usage |
| |
| hash_password <options> |
| |
| [cols=",",] |
| |=== |
| |
| |-h,--help |Displays help message |
| |
| |-e,--environment-var <arg> |Use value of the specified environment |
| variable as the password |
| |
| |-i,--input <arg> |Input is a file (or - for stdin) to read the |
| password from. Make sure that the whole input including newlines is |
| considered. For example, the shell command `echo -n foobar \| hash_password |
| -i -` will work as intended and just hash 'foobar'. |
| |
| |-p,--plain <arg> |Argument is the plain text password |
| |
| |-r,--logrounds <arg> |Number of hash rounds (default: 10). |
| |=== |
| |
| One of the options --environment-var, --plain or --input must be used. |
