An easy method is to use openssl command (MD5):

- run openssl command and type password and its confirmation

$ openssl passwd -1
Verifying - Password:

- create the user without specifying password
$ sudo useradd -c "your user" -m your_user

- change the user (note the single quotes around the encrypted password)

$ sudo usermod -p '$1$mJdspq9o$wZknKGNq433VsXKfK1EAq0' your_user

Useful also when a user wants to change his/her password and this way
can send the sysadmin the encrypted one to run the usermod command
