 # Luzifer / password
 
-This project is a rewrite of my former password generator written in Python. The intention is to provide a fast and secure way to generate one or more passwords using a CLI tool, a HTTPs page or a HTTPs API.
+The intention of this project is to provide a fast and secure way to generate one or more passwords using a CLI tool, a HTTPs page or a HTTPs API.
+
+For the security of the passwords there are several assertions:
+
+- The password may not contain pattern found on the keyboard or in alphabet
+- The password must have 3 or 4 different character groups in it depending on whether special characters are requested
+- The password may not have repeating characters
+- The API generator does not transmit or store any data about the generated passwords

 ### Via API
 
 - `/v1/getPassword` - Retrieve a password from the API
-  - `length=20` - Specify the length of the password to generate
+  - `date=true` - Set to `false` no to prepend the date to XKCD-style passwords
+  - `length=20` - Specify the length of the password to generate (the API only supports values between 4 and 128 - for more characters use the CLI)
   - `special=false` - Set to `true` to enable special characters
+  - `xkcd=false` - Set to `true` to enable XKCD-style passwords
