How to create encrypted password via command line

[Anne Moore]

Hi All
 
Does anyone know of a quick/painless way to create an encrypted {crypt}
password via the command like on Red Hat? I need my users to do this and I
don't want them to have to write much syntax, etc., as that will be too much
for them. I was hoping there was some built-in (or other) method that allows
creating an encrypted password, depending on what the user types in for the
password.
 
Thank you!
