Nemo

Nemo is a simple dictionary-based passphrase generator written in Go. It can generate "secure" (by the means of length and complexity) passphrases that are still easy to memorize.

Usage

The only requirement to run Nemo successfully is to provide a valid dictionary file. Everything else can be taken from the default values.

The possible command line options are:

Parameter           Description                                                 Default Value
---------------------------------------------------------------------------------------------------------------------------
-d                  whether the generated passphrases have to be distinct from  true
                    each other
-f                  comma separated list of random fill characters              "0,1,2,3,4,5,6,7,8,9,_,!,?"
-fill-before        whether to insert a fill character before or after a word   false
-fill-length-min    minimum length of the random fill insert                    1
-fill-length-max    maximum length of the random fill insert                    3
-i                  the dictionary input file(s)                                "language.dict"
-l                  the separator used to split the input file                  "\n"
-min                minimum passphrase length                                   30
-n                  number of passphrases to generate                           10
-r                  comma separated list of old new characters to replace in    "u\",ue,a\",ae,o\",oe,A\",Ae,O\",Oe,U\",Ue"
                    every dictionary word that is used for an actual passphrase

Where can I find good wordlists / dictionaries?
